1° L'autoxydationdel'éthyl-2-hexène-2-al, aldéhyde non saturé en α,β et ramifié en α, fournit comme acides caractéristiques: 1° l'éthyl-2-époxy-2,3-hexanoïque; 2° l'éthyl-2-hexène-2-oïque.
stearothermophilus (TKgst) was successfully engineered for the synthesis of aliphatic acyloins with varying carbon backbone lengths (C5−C10) based on protein structure‐guided studies. Efficient TKgst variants were identified with enhanced activities for substrate combinations of aliphatic aldehydes as acceptors together with aliphatic pyruvate homologues as donors. The TKgst single variant L382F was

In one aspect, this invention relates to production of useful fermentation end-products from biomass through simultaneous hydrolysis and fermentation by a microorganism, such as
Clostridium phytofermentans
. The invention also relates to the development of a process for efficient pretreatment and conversion of lignocellulosic biomass to end-products with high conversion efficiency (yield). In another aspect, methods for producing a fermentation end-product by fermenting hexose (C6) and pentose (C5) sugars with a microorganism, such as
Clostridium phytofermentans
are disclosed herein.
Methods, enzymes, recombinant microorganism, and microbial systems are provided for converting polysaccharides, such as those derived from biomass, into suitable monosaccharides or oligosaccharides, as well as for converting suitable monosaccharides or oligosaccharides into commodity chemicals, such as biofuels. Commodity chemicals produced by the methods described herein are also provided. Commodity chemical enriched, refinery-produced petroleum products are also provided, as well as methods for producing the same.
