Metabolic engineering of acetoin and meso‐2, 3‐butanediol biosynthesis in E. coli [PDF]

Biotechnology Journal, 2010
AbstractThe functional reconstruction of acetoin and meso‐2,3‐butanediol (meso‐2,3‐BD) biosynthetic pathways in Escherichia coli have been explored systematically. Pathway construction involved the in vsivo screening of prospective pathway isozymes of yeast and bacterial origin.

Metabolic engineering of [PDF]

Food Chemistry: X
Post-acidification during storage limits the use of multiple probiotics in fermented dairy products. In this study, the ldh gene was deleted in Lacticaseibacillus paracasei Zhang (LCZ), resulting in 45% reduction in lactic acid production.

Effect of alsD deletion and overexpression of nox and alsS on diacetyl and acetoin production by Lacticaseibacillus casei during milk fermentation

Journal of Dairy Science, 2022
: Diacetyl and acetoin are key aroma components of fermented milk but are produced in low concentrations by starter cultures. In this study, we expressed NADH oxidase, acetolactate synthase, and inactivated acetolactate decarboxylase in ...
