Dileep Sai Kumar Palur, Shannon R Pressley, Shota Atsumi
Molecules (Basel, Switzerland), 28, 3, 03 Feb. 2023, [Peer-reviewed], [Invited], [Last author, Corresponding author], [International Magazine]
English, Scientific journal, Human milk oligosaccharides (HMOs) are complex nonnutritive sugars present in human milk. These sugars possess prebiotic, immunomodulatory, and antagonistic properties towards pathogens and therefore are important for the health and well-being of newborn babies. Lower prevalence of breastfeeding around the globe, rising popularity of nutraceuticals, and low availability of HMOs have inspired efforts to develop economically feasible and efficient industrial-scale production platforms for HMOs. Recent progress in synthetic biology and metabolic engineering tools has enabled microbial systems to be a production system of HMOs. In this regard, the model organism Escherichia coli has emerged as the preferred production platform. Herein, we summarize the remarkable progress in the microbial production of HMOs and discuss the challenges and future opportunities in unraveling the scope of production of complex HMOs. We focus on the microbial production of five HMOs that have been approved for their commercialization. - Light-induced production of isobutanol and 3-methyl-1-butanol by metabolically engineered cyanobacteria.

English, Scientific journal, BACKGROUND: Cyanobacteria are engineered via heterologous biosynthetic pathways to produce value-added chemicals via photosynthesis. Various chemicals have been successfully produced in engineered cyanobacteria. Chemical inducer-dependent promoters are used to induce the expression of target biosynthetic pathway genes. A chemical inducer is not ideal for large-scale reactions owing to its high cost; therefore, it is important to develop scaling-up methods to avoid their use. In this study, we designed a green light-inducible alcohol production system using the CcaS/CcaR green light gene expression system in the cyanobacterium Synechocystis sp. PCC 6803 (PCC 6803). RESULTS: To establish the green light-inducible production of isobutanol and 3-methyl-1-butanol (3MB) in PCC 6803, keto-acid decarboxylase (kdc) and alcohol dehydrogenase (adh) were expressed under the control of the CcaS/CcaR system. Increases in the transcription level were induced by irradiation with red and green light without severe effects on host cell growth. We found that the production of isobutanol and 3MB from carbon dioxide (CO2) was induced under red and green light illumination and was substantially repressed under red light illumination alone. Finally, production titers of isobutanol and 3MB reached 238 mg L-1 and 75 mg L-1, respectively, in 5 days under red and green light illumination, and these values are comparable to those reported in previous studies using chemical inducers. CONCLUSION: A green light-induced alcohol production system was successfully integrated into cyanobacteria to produce value-added chemicals without using expensive chemical inducers. The green light-regulated production of isobutanol and 3MB from CO2 is eco-friendly and cost-effective. This study demonstrates that light regulation is a potential tool for producing chemicals and increases the feasibility of cyanobacterial bioprocesses. - Adaptive laboratory evolution for improved tolerance of isobutyl acetate in Escherichia coli.

English, Scientific journal, Previously, Escherichia coli was engineered to produce isobutyl acetate (IBA). Titers greater than the toxicity threshold (3 g/L) were achieved by using layer-assisted production. To avoid this costly and complex method, adaptive laboratory evolution (ALE) was applied to E. coli for improved IBA tolerance. Over 37 rounds of selective pressure, 22 IBA-tolerant mutants were isolated. Remarkably, these mutants not only tolerate high IBA concentrations, they also produce higher IBA titers. Using whole-genome sequencing followed by CRISPR/Cas9 mediated genome editing, the mutations (SNPs in metH, rho and deletion of arcA) that confer improved tolerance and higher titers were elucidated. The improved IBA titers in the evolved mutants were a result of an increased supply of acetyl-CoA and altered transcriptional machinery. Without the use of phase separation, a strain capable of 3.2-fold greater IBA production than the parent strain was constructed by combing select beneficial mutations. These results highlight the impact improved tolerance has on the production capability of a biosynthetic system. - Synthetic Biology Approaches for Improving Chemical Production in Cyanobacteria.

English, Scientific journal, Biological chemical production has gained traction in recent years as a promising renewable alternative to traditional petrochemical based synthesis. Of particular interest in the field of metabolic engineering are photosynthetic microorganisms capable of sequestering atmospheric carbon dioxide. CO2 levels have continued to rise at alarming rates leading to an increasingly uncertain climate. CO2 can be sequestered by engineered photosynthetic microorganisms and used for chemical production, representing a renewable production method for valuable chemical commodities such as biofuels, plastics, and food additives. The main challenges in using photosynthetic microorganisms for chemical production stem from the seemingly inherent limitations of carbon fixation and photosynthesis resulting in slower growth and lower average product titers compared to heterotrophic organisms. Recently, there has been an increase in research around improving photosynthetic microorganisms as renewable chemical production hosts. This review will discuss the various efforts to overcome the intrinsic inefficiencies of carbon fixation and photosynthesis, including rewiring carbon fixation and photosynthesis, investigating alternative carbon fixation pathways, installing sugar catabolism to supplement carbon fixation, investigating newly discovered fast growing photosynthetic species, and using new synthetic biology tools such as CRISPR to radically alter metabolism. - Microbial production of human milk oligosaccharide lactodifucotetraose.

English, Scientific journal, Human milk oligosaccharides (HMOs) are potent bioactive compounds that modulate neonatal health and are of interest for development as potential drug treatments for adult diseases. The potential of these molecules, their limited access from natural sources, and difficulty in large-scale isolation of individual HMOs for studies and applications have motivated the development of chemical syntheses and in vitro enzymatic catalysis strategies. Whole cell biocatalysts are emerging as alternative self-regulating production platforms that have the potential to reduce the cost for enzymatic synthesis of HMOs. Whole cell biocatalysts for the production of short-chained, linear and small monofucosylated HMOs have been reported but those for fucosylated structures with higher complexity have not been explored. In this study, we established a strategy for producing a difucosylated HMO, lactodifucotetraose (LDFT), from lactose and L-fucose in Escherichia coli. We used two bacterial fucosyltransferases with narrow acceptor selectivity to drive the sequential fucosylation of lactose and intermediate 2'-fucosyllactose (2'-FL) to produce LDFT. Deletion of substrate degradation pathways that decoupled cellular growth from LDFT production, enhanced expression of native substrate transporters and modular induction of the genes in the LDFT biosynthetic pathway allowed complete conversion of lactose into LDFT and minor quantities of the side product 3-fucosyllactose (3-FL). Overall, 5.1 g/L of LDFT was produced from 3 g/L lactose and 3 g/L L-fucose in 24 h. Our results demonstrate promising applications of engineered microbial biosystems for the production of multi-fucosylated HMOs for biochemical studies. - Nonphotosynthetic Biological CO2 Reduction.

English, Scientific journal, Alarming changes in environmental conditions have prompted significant research into producing renewable commodities from sources other than fossil fuels. One such alternative is CO2, a determinate greenhouse gas with historically high atmospheric levels. If sequestered, CO2 could be used as a highly renewable feedstock for industrially relevant products and fuels. The vast majority of atmospheric CO2 fixation is accomplished by photosynthetic organisms, which have unfortunately proven difficult to utilize as chassis for industrial production. Nonphotosynthetic CO2 fixing microorganisms and pathways have recently attracted scientific and commercial interest. This Perspective will review promising alternate CO2 fixation strategies and their potential to supply microbially produced fuels and commodity chemicals, such as higher alcohols. Acetogenic fermentation and microbial electrosynthesis are the primary focuses of this review. - Metabolic engineering tools in model cyanobacteria.

English, Scientific journal, Developing sustainable routes for producing chemicals and fuels is one of the most important challenges in metabolic engineering. Photoautotrophic hosts are particularly attractive because of their potential to utilize light as an energy source and CO2 as a carbon substrate through photosynthesis. Cyanobacteria are unicellular organisms capable of photosynthesis and CO2 fixation. While engineering in heterotrophs, such as Escherichia coli, has result in a plethora of tools for strain development and hosts capable of producing valuable chemicals efficiently, these techniques are not always directly transferable to cyanobacteria. However, recent efforts have led to an increase in the scope and scale of chemicals that cyanobacteria can produce. Adaptations of important metabolic engineering tools have also been optimized to function in photoautotrophic hosts, which include Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-Cas9, 13C Metabolic Flux Analysis (MFA), and Genome-Scale Modeling (GSM). This review explores innovations in cyanobacterial metabolic engineering, and highlights how photoautotrophic metabolism has shaped their development. - Electrical-biological hybrid system for CO2 reduction
