UNLABELLED BACKGROUND High tolerance to ethanol is a desirable characteristics for ethanologenic strains used in industrial ethanol fermentation. A deeper understanding of the molecular mechanisms underlying ethanologenic strains tolerance of ethanol stress may guide the design of rational strategies to increase process performance in industrial alcoholic production. Many extensive studies h...
BACKGROUND With the increasing global crude oil crisis and resulting environmental concerns, the production of biofuels from renewable resources has become increasingly important. One of the major challenges faced during the process of biofuel production is the low tolerance of the microbial host towards increasing biofuel concentrations. RESULTS Here, we demonstrate that the ethanol toleranc...
BACKGROUND Zymomonas mobilis ZM4 is a capable ethanologenic bacterium with high ethanol productivity and ethanol tolerance. Previous studies indicated that several stress-related proteins and changes in the ZM4 membrane lipid composition may contribute to ethanol tolerance. However, the molecular mechanisms of its ethanol stress response have not been elucidated fully. METHODOLOGY/PRINCIPAL F...
Recently, an in vitro enzymatic cascade was constructed to transform glycerol into the high-value platform chemical pyruvate. However, low activity of dihydroxy acid dehydratase from Sulfolobus solfataricus (SsDHAD) limited efficiency. In this study, reduction pyruvate catalyzed by d-lactate dehydrogenase Pseudomonas aeruginosa PAO1 used assay activities dehydratases. Dihydroxy Paralcaligenes u...
