Environmental and physiological factors affecting the succinate product ratio during carbohydrate fermentation by Actinobacillus sp. 130Z
Actinobacillus sp. 130Z fermented glucose to the major products succinate, acetate, and formate. Ethanol was formed as a minor fermentation product. Under CO2-limiting conditions, less succinate and
1-Cys Peroxiredoxin, a Bifunctional Enzyme with Glutathione Peroxidase and Phospholipase A2 Activities*
TLDR
The results suggest that Ser32 in the GDSWG consensus sequence provides the catalytic nucleophile for the hydrolase activity of aiPLA2, while Cys47 in the PVCTTE consensus sequence is at the active site for peroxidase activity.
Effect of small molecules on the dipalmitoyl lecithin liposomal bilayer: III. Phase transition in lipid bilayer
TLDR
Observations are consistent with the hypothesis that the type of effect induced by an additive on the phase transition profile of the bilayer is related to the position of localization of the additive along the thickness of the Bilayer.
Challenges in Metal Recycling
Metals are, in principle, infinitely recyclable. In reality, metal recycling is generally inefficient and in many cases non-existent. This is due to a number of factors ranging from social behaviour
Continuous production of mixed alcohols and acids from carbon monoxide
TLDR
At low pH values, direct, steady-state fermentation of carbon monoxide to alcohols has been verified and of major significance is the production of butanol from Carbon monoxide in pure culture, which provides a potential mechanism for direct bioconversion of synthesis gas to butanol.
