English, Scientific journal, In this study, spore heat resistance and growth ability at refrigeration temperatures of Bacillus spp. and Paenibacillus spp. were determined. The spore D90°C of 67.6% (23 of 34 strains) of Bacillus and 73.9% (17 of 23 strains) of Paenibacillus was less than 15 min. The growth abilities of both genera were equivalent at 10°C. However, 71.1% (32 of 45 strains) of Paenibacillus and only 6.3% (3 of 48 strains) of Bacillus cereus group could grow at 4°C. Eight B. cereus strains formed spores with higher heat resistance compared to the other Bacillus strains assessed; however, they did not grow at tempreratures below 10°C. Conversely, four Paenibacillus strains formed spores with heat resistance equivalent to that of the eight B. cereus strains and grew at 6°C or lower. In particular, Paenibacillus sp. JCM13343 formed the highest heat-resistant spores (D90°C = 136.1 min) and grew well at 4°C. These results indicate that Paenibacillus can grow in processed foods during refrigerated storage and has the potential to cause spoilage as well as Bacillus. Therefore, Paenibacillus should be considered as one of the targets for microbiological control in refrigerated processed foods. - Long filamentous state of Listeria monocytogenes induced by sublethal sodium chloride stress poses risk of rapid increase in colony-forming units

English, Scientific journal, In Mitchell's chemiosmotic theory, a proton (H+) motive force across the membrane (Δp), generated by the respiratory chain, drives F1Fo-ATPase for ATP production in various organisms. The bulk-base chemiosmotic theory cannot account for ATP production in alkaliphilic bacteria. However, alkaliphiles thrive in environments with a H+ concentrations that are one-thousandth (ca. pH 10) the concentration required by neutralophiles. This situation is similar to the production of electricity by hydroelectric turbines under conditions of very limited water. Alkaliphiles manage their metabolism via various strategies involving the cell wall structure, solute transport systems and molecular mechanisms on the outer surface membrane. Our experimental results indicate that efficient ATP production in alkaliphilic Bacillus spp. is attributable to a high membrane electrical potential (ΔΨ) generated for an attractive force for H+ on the outer surface membrane. In addition, the enhanced F1Fo-ATPase driving force per H+ is derived from the high ΔΨ. However, it is difficult to explain the reasons for high ΔΨ formation based on the respiratory rate. The Donnan effect (which is observed when charged particles that are unable to pass through a semipermeable membrane create an uneven electrical charge) likely contributes to the formation of the high ΔΨ because the intracellular negative ion capacities of alkaliphiles are much higher than those of neutralophiles. There are several variations in the adaptation to alkaline environments by bacteria. However, it could be difficult to utilize high ΔΨ in the low aeration condition due to the low activity of respiration. To explain the efficient ATP production occurring in H+-less and air-limited environments in alkaliphilic bacteria, we propose a cytochrome c-associated "H+ capacitor mechanism" as an alkaline adaptation strategy. As an outer surface protein, cytochrome c-550 from Bacillus clarkii possesses an extra Asn-rich segment between the region anchored to the membrane and the main body of the cytochrome c. This structure may contribute to the formation of the proton-binding network to transfer H+ at the outer surface membrane in obligate alkaliphiles. The H+ capacitor mechanism is further enhanced under low-aeration conditions in both alkaliphilic Bacillus spp. and the Gram-negative alkaliphile Pseudomonas alcaliphila. - Antmicrobial and antibiofilm activity of sulfated polysaccharides from marine algae against dental plaque bacteria

Japanese, Scientific journal,Morganella psychrotolerans is a novel psychrotrophic histamine producing bacterium and seems to cause histamine fish poisoning (scombroid poisoning). However, there is little information about the occurrence and histamine producing ability of this bacterium for food contamination. To elucidate the contamination status of M. psychrotolerans, we used an MPN-PCR method that can determine bacterial number more sensitive than a traditional plating method. Many kinds of fish samples purchased in Hokkaido and water samples collected in Hakodate area were used in this study. Eighty-five MPN-PCR positive samples were found in total 192 samples (44.3%) and thirty-seven strains of M. psychrotolerans were isolated from the positive samples. It suggests M. psychrotolerans is widely distributed in retail seafood product in Japan. Then the amounts of histamine produced by M. psychrotolerans isolates were investigated. All isolates produced more than 4,000 mg/L (4,000 ppm) of histamine after 48 h incubation at 25℃. Next, the growth and histamine production of M. psychrotolerans (JCM 16473T, strain Mps. 3 from a horse mackerel sample) and Photobacterium phosphoreum NBRC 103031T was compared in the liquid media containing 0.1 or 2.0% NaCl at 4℃. At 0.1% NaCl, histamine concentration produced by M. psychrotolerans was higher than that by P. phosphoreum. It indicates M. psychrotolerans will also become one of the important bacteria associated with histamine-poisoning at refrigeration temperature on seafood, as well as P. phosphoreum.

English, Scientific journal, Growth requirements for maximum production of pediocin Iz3.13 by Pediococcus pentosaceus Iz3.13 were studied. Physical and chemical parameters that enhanced pediocin production included incubation in static broth at 30℃, with an initial pH of 4.5. Optimum nutritional conditions that enhanced pediocin Iz3.13 production were 3.5% Trypticase peptone, 3.5% Phytone peptone or 5.0% Proteose peptone No.3 as nitrogen sources, and glucose or maltose as carbon sources. Supplementing growth media with beef extract and MgCl2 also enhanced production. This study proposes an optimized growth medium containing 5.0% Proteose peptone No.3, 3.5% Phytone peptone, 2.5% glucose, 1.5% MgCl2, 3.0% beef extract and 0.25% K2HPO4. This medium significantly enhanced pediocin Iz3.13 production (5.1 fold increase) as compared to a basal medium. - Comparison and improvement of detection media for sub-lethal injured Clostridium perfringens

Japanese, Clostridium perfringens(ウェルシュ菌)は芽胞形成グラム陽性の偏性嫌気性細菌であり、土壌、河川などの自然界や人、動物の腸管などに広く常在する細菌である。本菌の中にはエンテロトキシンを産生するものが存在し、そのような毒素産生株に汚染された食品を摂取することで食中毒が発生する。食品や環境からC. perfringensを分離する方法はこれまで多数報告されており、そのいくつかは公定法または標準法として採用されている。我が国における食品からのC. perfringens の検出には、3種類の培地、すなわちカナマイシン含有卵黄加CW寒天培地、Tryptose sulfite cycloserine(TSC)寒天培地およびハンドフォード改良寒天培地が食品衛生検査指針(2003)で推奨されており、その中でもカナマイシン含有卵黄加CW寒天培地が平板塗抹法による生菌数測定を行う際に良く利用されている。一方、海外ではTSC寒天培地を推奨している場合が多い。これらの培地は、比較的類似した成分を基礎成分としているが、選択剤として含有する抗生物質の種類と濃度に大きな差異がある。本研究では、我が国でC. perfringens の検出に頻繁に用いられている選択培地での加熱損傷C. perfringens の検出感度および損傷回復剤の効果について検討した。 - Fluorescent in situ hybridization in combination with filter cultivation (FISHFC) method for specific detection and enumeration of viable Clostridium perfringens

Japanese, Scientific journal, The purpose of this study was to develop low cost color indicators of temperature abuse in the cold chain. To develop the indicators, bacterial strain sk22 isolated from commercial cod was used. Strain sk22 can grow and produce acid from carbohydrate at 4℃. Incubating sk22 in modified Oxidation- Fermentation broth at 12℃ (with initial inoculums levels of 106 and 103 CFU/ml) resulted in color changes of 35 and 72 hours respectively. Further, addition of buffer delayed color changes. Therefore by adjusting inoculum levels and/or buffer concentration, timing of color change could be controlled. To make the indicator safe for food use, the suitability of nine pigments and food grade buffers was tested to judge their effects on the color change. Red cabbage pigment was the most suitable one of the tested pigments because color change was clear. Furthermore, addition of food grade ammonium sulfate as a buffer enhanced clarity of color change. - Effect of exogenous methyl jasmonate on lipoxygenase activity in a red alga Porphyra yezoensis

Japanese, Scientific journal, The survival of Listeria monocytogenes IID 581 was determined in filtered sterilized artificial seawater (ASW), natural seawater (NSW) and ultra pure water (UPW) microsoms. L. monocytogenes IID581 maintained the culturable state longer at lower temperature in ASW and NSW. However, the pathogen lost culturability in UPW rapidly at all temperatures examined (5, 10 and 30°C).
The culturability of L. monocytogenes IID 581 cells was determined by spread plate count (TSAYE), and the cell activity was observed under a fluorescence microscope, using the LIVE/DEAD BacLightTM bacteria viability kit. There were significant differences between the results obtained from those two methods at all temperatures (10, 20 and 30°C) in ASW. Greater differences were seen between the above two methods in ASW at higher temperature, while there was little difference between them in UPW. The results indicate that L. monocytogenes IID581 enters a viable but non-culturable (VBNC) state in ASW and both temperature and the concentration of inorganic salts influence the transition to the VBNC state. - Inhibition of Listeria monocytogenes in cold-smoked salmon by Camobacterium piscicola CS526 isolated from frozen surimi

English, Scientific journal, Sardine moist meals were inoculated with Aspergillus oryzae IFO 4202 seed and fermented. Accompanying the growth of the fungus, the chemical composition of the meals significantly changed during incubation. The fermentation contributed to antioxidation of lipids and reduction of histamine. Glucose supplement during fermentation was effective in inhibiting the production of volatile basic nitrogenous compounds. Fermented meals maintained superior quality of the proteins, protecting amino acid residues during incubation. The initial bacterial cell counts in meals were 3×102 CFU/g and reached 108 CFU/g in 72-h incubation. The Gram-negative rod-shaped bacteria, Pseudomonas spp., Moraxella spp. and Acinetobacter spp., were predominant in the initial meals. Gram-positive bacteria, especially Micrococcus spp., gradually became predominant during incubation. Fermentation and glucose supplement enhanced this predominancy of Micrococcus spp. during incubation. Fermentation with Aspergillus oryzae in the presence of glucose was considered to be effective for improvement of the chemical, nutritional and microbiological quality of fish meals. - Comparative sequence analyses of the genes coding for 16S rRNA of Lactobacillus casei-related taxa

YAMAZAKI KOJI
This study was investigated the characterization of bacteriocin-resistant Listeria monocytogenes and the development of inhibition method using bacteriocin (nisin A) against L.monocytogenes in seafood products. Nisin-resistant L.monocytogenes showed that the affinity between the cell surface of the resistant strains and nisin molecule was reduced, compared with those of wild strains. And protein profiles on the cytoplasmic membrane and the structure of peptidoglycan layer of the nisin-resistant strains would be also changed. The combination of nisin A and pectin digests was effective for the control of L.monocytogenes growth in raw salmon roes seasoned with soy-sauce at refrigeration temperature, suggesting that the combination of them will be a promising tool to ensure food safety to L.monocytogenes contamination in seafood.

YAMAZAKI Koji
This study was undertaken to establish a new technology, using anti-listerial peptides, to ensure food safety. Production of an anti-listerial peptide, piscicocin CS526, produced by Carnobacterium maltaromaticum CS526 was regulated with environmental pH. A simple one-step isolation method, based on the adsorption-desorption property to bacterial cells, was developed for piscicocin CS526. A freeze-dried bioactive fermented powder with anti-listerial peptide produced by C.maltaromaticum FS-B was effective for the control of L.monocytogenes in a food model at refrigeration and frozen temperature, suggesting that the fermented powder will be a powerful tool to ensure food safety against L.monocytogenes contamination in foods such as ready-to-eat products.

申請者が水産食品から分離に成功した新規抗菌ペプチド産生菌Carnobacterium piscicola CS526で乳清タンパク質を発酵・粉末化し,これを用いたready-to-eat食品モデル中でのListeria monocytogenesの制御について検討し,Piscicocin CS526含有乳清発酵粉末を挽肉に添加することで,L.monocytogenesの発育を効果的に阻止できることを明らかにした。
また,LImonocytogenesのPiscicocin CS526耐性獲得頻度について調べ,10^<-4>〜10^<-5>の割合でClass IIaバクテリオシンであるPiscicocin CS526耐性菌が出現することを明らかにした。一方・食品中でのPiscicocin CS526耐性L.monocytogenesの制御を考え,様々な抗菌物質に対するPiscicocin CS526耐性菌の交差耐性の有無を調べ,各種抗生物質や食品への添加が許可されている既存の抗菌物質約30種に対して交差耐性のないことを示した。また,耐性株では親株に比べてPiscicocinCS526の細胞吸着量が低下していることを明らかにし,耐性株での細胞膜表面の負電荷領域の減少が耐性獲得の原因のひとつであることを明らかにした。さらに,他の抗菌性物質との併用によりL.monocytogenesのregrowthを阻止できることから耐性獲得が抑制されることを示した。

The purpose of this study was to establish a rapid molecular method for detecting histamine-producing bacteria, the causative agent of scombroid poisoning. The Photobacterium histaminum hdc gene encoding an inducible histidine decarboxylase(HisDcase), that is involved in a large scale excretion of histamine extracellularly, has been cloned by using the N-terminal amino acid sequence of the purified protein. The cloned chromosomal fragment containing the hdc gene was sequenced. Oligonucleotide primers were designed for the PCR amplification of hdc genes of P.histaminum and several other gram-negative histamine-producing bacteria. The optimal PCR conditions for detecting histamine-producing bacteria were evaluated.
Also, the TaqMan PCR assay for rapid detection of bacteria was evaluated, using Salmonella. This system uses the 5' nuclease activity of Taq DNA polymerase which digests an internal fluorogenic probe to monitor the amplification of the target gene. These results indicate that TaqMan is a reliable and rapid method for Salmonella analysis in the food industry.

Using specific region of 16S rRNA gene, RT-PCR method enabled the detection of A.acidoterrestris, a new type of thermoacidophilic spoilage bacterium in acidic beverages. A PCR method for Clostridium perfringens with fluorogenic probes was also developed. Additionally, PCR fragment length typing of the internal spacer region between the 16S and 23S rRNA genes was found to be rapid and reliable to distinguish C.perfringens among clostridia. DNA/RNA extracting methods from food, developed in this study, were proved to be practical.

イカ墨中の抗菌性物質を検索するため,まず様々な種類のイカ墨の抗菌性について比較検討した。その結果,Staphylococcus aureusとS. epidermidisの発育に対して,スルメイカおよびモンゴイカ墨でほぼ同等の発育遅延効果を認めた。しかしヤリイカ墨には発育遅延効果は認められなかった。またこれらスルメイカおよびモンゴイカ墨の抗菌性は,イカ塩辛の熟成初期および中期に優勢となる S. warneri, S. xylosusまたはMicrococcus spp.の発育には影響を示さなかった。
次に,モンゴイカ墨の抗菌特性についてS. epidermidisとS. warneriを指標菌に用い検討した結果,イカ墨濃度3%以上および食塩濃度10%以上の条件下においてその抗菌性が発揮されることが明らかとなった。また作用pHについて検討した結果,イカ塩辛熟成初期と同等のpH6前後では,発育抑制効果が認められたが,pH6.4以上になるとその効果が静菌効果に減弱してしまうことを見出した。しかし,「イカ塩辛黒作り」の熟成期間を通じて優勢となるS. warneriに対してはpH6付近では発育遅延効果は見られず,さらにイカ墨が存在しない場合にはpH7に近づくにつれて発育速度が徐々に低下するのに対して,墨存在下ではいずれのpHにおいても発育速度には変化は見られなかった。
これらのことから,「黒作り」が「赤作り」と比較して,S. warneriが優勢となるより単純な菌相を形成することおよび食中毒菌であるS. aureusが検出されない理由のひとつに,熟成巾におけるpH変動と連動したイカ墨成分のS. warneriに対する増殖促進作用とS. epidermidisに対する増殖抑制作用およびイカ墨成分のS. aureusに対する抗菌作用が上手く発揮されるためと推察した。

低酸性飲料変敗原因菌の迅速検出法を確立するために,まず変敗飲料缶詰から変敗原因菌の分離を試みた結果,至適発育pHが4.0-4.5にあり中性付近では発育できない好酸性菌が新たに分離でき,Bergey's manual of systematic bacteriologyに準拠して同定するとBacillus属に分類された。しかしながら種レベルまで性状が一致するものの記載が認められなかったため,これら細菌の16SリボゾームRNA(rRNA)塩基配列をおよそ1500塩基決定し,DDBJ登録されている類縁菌種の16SrDNA塩基配列と比較した結果,Alicyclobacillus acidoterrestrisと92.5-93.0%,A.acidocardariusと92.3-92.8%のホモロジーを示し,これらの結果から本分離株はいずれもAlicyclobacillus属に分類されたが,種名までは明らかにできなかった。また本分離株とその類縁菌種との系統的関係を,近隣接続法(NJ法)を用いて推定した結果,Alicyclobacillus属と系統的に非常に近い関係にあったが,いずれの分離菌株ともこれまで報告されているAlicyclobacillus属とは異なるクラスターを形成した。これらのことから,本分離菌株が新種の可能性を有していると考えられた。
次に,低酸性飲料変敗原因菌の16SrRNA塩基配列から,迅速検出用プライマー部位を2カ所選定(190Fおよび490R)し,それらの特異性および感度について検討した。その結果,これらプライマーは非常に高い特異性を有しており,また少なくとも100agのDNAが存在すれば検出可能の範囲であることが確認できた。さらに現在,従来法とPCR法を用いた本手法との比較を行っており,平成6年度当初の計画はほぼ達成されたと考えている。

The effect of various concentrations of the addition of squid liver and to "Ika-Shiokara" with 10% salt were examined on the changes of microflora and chemical prooeties of "Ika-Shiokara" and the inoculated pathogenic organism, Staphylococcus aureus.
In the case of the "Ika-Shokara" without the addition of squid liver, the dominant species of S.warneri found in the early stage (2-4days) were replaced by Micrococci in the later stage of ripening.In the case of the sample with 1% squid liver, the dominant microorganism was S.warneri in the early stage, and the Staphylococci including S.warneri were replaced by Micrococci during the later stage of ripening (4-14days).In the case, the quility of "Ika-Shiokara" was decreased with the shift of dominant Staphylococci to Micrococci.In the case of 3% liver addition, among the dominant Staphylococci over the ripening preocess, S.epidermidis were shown to predominated on the last day of sampling.The inoculated S.aurues decreased during the ripening process with the addition of aquid liver 3-6%.The squid ink had a particulaly strong effect, and elongated the period of edibility.
S.epidermidis has never been isolated from "Ika-Shiokara" with the addition of ink, and was therefore isolated without ink.In the in vitro experiments, both S.epidermidis and S.aureus were inhibited by the extracts of heated squid ink.These findings suggest that the addition of squid liver and ink plays important roles in the formation of specific microflora of " Ika-Shiokara", and there are heat stable inhibitory substances in the squid liver and ink.
