Published: May 2012

Ethanol-producing Escherichia coli strain KO11 consumed 99% of the glucose and only 13% of the xylose in a mixture of glucose (60g/L) and xylose (40g/L) during the 72-h fermentation at 30°C. The deletion mutants ΔptsG, ΔmanXYZ, and ΔptsG/manXYZ utilized 42%, 78%, and 35% of the glucose and 50%, 32%, and 32% of the xylose, respectively.

Endogenous ethanol production emerges as a mechanism of nonalcoholic steatohepatitis, obesity, diabetes and auto-brewery syndrome. To identify ethanol-producing microbes in humans, we used the NCBI taxonomy browser and the PubMed database with an automatic query and manual verification. 85 ethanol-producing microbes in human were identified.

Background/aim: Alterations in gut microbiota are associated with the pathogenesis of metabolic diseases, including metabolic-associated fatty liver disease (MAFLD). The aim of this study was to evaluate gut microbiota composition and functionality in patients with morbid obesity with different degrees of MAFLD, as assessed by biopsy.

Subjects/methods: 110 patients with morbid obesity were evaluated by biopsy obtained during bariatric surgery for MAFLD.

Improvement of ethanol and 2,3-butanediol production in Saccharomyces cerevisiae by ATP wasting.

Microb Cell Fact

October 2023

Department of Bioinformatics Engineering, Graduate School of Information Science and Technology, Osaka University, 1-5 Yamadaoka, Suita, Osaka, 565-0871, Japan.

Background: "ATP wasting" has been observed in C metabolic flux analyses of Saccharomyces cerevisiae, a yeast strain commonly used to produce ethanol. Some strains of S. cerevisiae, such as the sake strain Kyokai 7, consume approximately two-fold as much ATP as laboratory strains.

Ethanol-producing dysbiotic gut microbiota could accelerate the progress of non-alcoholic fatty liver disease (NAFLD). Metformin demonstrated some benefits in NAFLD. In the present study, we tested the ability of metformin to modify ethanol-producing gut bacterial strains and, consequently, retard the progress of NAFLD.

Background: Bioconversion of levoglucosan, a promising sugar derived from the pyrolysis of lignocellulose, into biofuels and chemicals can reduce our dependence on fossil-based raw materials. However, this bioconversion process in microbial strains is challenging due to the lack of catalytic enzyme relevant to levoglucosan metabolism, narrow production ranges of the native strains, poor cellular transport rate of levoglucosan, and inhibition of levoglucosan metabolism by other sugars co-existing in the lignocellulose pyrolysate. The heterologous expression of eukaryotic levoglucosan kinase gene in suitable microbial hosts like Escherichia coli could overcome the first two challenges to some extent; however, no research has been dedicated to resolving the last two issues till now.
