High-Throughput Screening of a 2-Keto-L-Gulonic Acid-Producing Gluconobacter oxydans Strain Based on Related Dehydrogenases.

Yue Chen et al.

Frontiers in bioengineering and biotechnology, 7, 385-385 (2020-01-11)

High-throughput screening is a powerful tool for discovering strains in the natural environment that may be suitable for target production. Herein, a novel enzyme-based high-throughput screening method was developed for rapid screening of strains overproducing 2-keto-L-gulonic acid (2-KLG). The screening

Production of 2-keto-L-gulonic acid by metabolically engineered Escherichia coli.

Weizhu Zeng et al.

Bioresource technology, 318, 124069-124069 (2020-09-12)

The 2-keto-L-gulonic acid (2-KLG) is the direct precursor for industrial vitamin C production. The main biosynthetic method for 2-KLG production is the classical two-step fermentation route. However, disadvantages of this method are emerging, including high consumption of energy, difficulties in

Biochemical and mutational analyses of a Trametes pyranose oxidase and comparison of its mutants in breadmaking.

Mengzhu Li et al.

AMB Express, 8(1), 38-38 (2018-03-15)

Pyranose oxidase (POx) is a homotetrameric flavoprotein that catalyzes the oxidation of pyranose-configured sugars at position C-2 to corresponding 2-ketoaldoses. The wide substrate specificity makes POx potential for application in various biotechnological industries. In the present study we reported the

Selective carbon sources influence the end products of microbial nitrate respiration.

Hans K Carlson et al.

The ISME journal, 14(8), 2034-2045 (2020-05-07)

Respiratory and catabolic genes are differentially distributed across microbial genomes. Thus, specific carbon sources may favor different respiratory processes. We profiled the influence of 94 carbon sources on the end products of nitrate respiration in microbial enrichment cultures from diverse

Reconstruction of amino acid biosynthetic pathways increases the productivity of 2-keto-L-gulonic acid in Ketogulonicigenium vulgare-Bacillus endophyticus consortium via genes screening.

Cai-Hui Pan et al.

Journal of industrial microbiology & biotechnology, 44(7), 1031-1040 (2017-03-12)

Defect in the amino acid biosynthetic pathways of Ketogulonicigenium vulgare, the producing strain for 2-keto-L-gulonic acid (2-KGA), is the key reason for its poor growth and low productivity. In this study, five different strains were firstly reconstructed by expressing absent
