Fermentation of d-xylose by Clostridium butyricum LMG 1213t1 in chemostats
TLDR
Clostridium butyricum LMG 1213t 1 was able to grow on d -xylose and l -arabinose in a minimal medium and it is proposed that this was caused by an additional ATP expenditure for the active transport of d - xylose across the cell membrane.About:

A comprehensive and quantitative review of dark fermentative biohydrogen production
TL;DR: This review summarizes the work done on pure and defined co-culture dark fermentative BHP since the year 1901 and suggests a Design of Experiments strategy should be preferred for efficient bioprocess development and optimization of BHP aiming at improving medium, cultivation conditions and revealing inhibitory effects.

Extractive fermentation for butyric acid production from glucose by Clostridium tyrobutyricum.
Zetang Wu,Shang-Tian Yang +1 more
TL;DR: Improved performance for extractive fermentation can be attributed to the reduced product inhibition by selective removal of butyric acid from the fermentation broth, which resulted in higher product concentration and product purity.

Construction of xylose-assimilating Saccharomyces cerevisiae
TL;DR: The transformants of S. cerevisiae harboring the resultant plasmids produced xylose reductase constitutively at a rate about 3 times higher than P. stipitis, but could not assimilatexylose due to the deficient conversion of xylitol to xylulose.
Journal ArticleDOI
Advances in biotechnological production of butyric acid
TL;DR: The main metabolic pathways of butyrate production, and possibilities for their control are outlined, and extraction alone or extraction combined with simultaneous stripping of the organic phase into the second aqueous phase (pertraction) seem to be the most suitable methods for on-linebutyrate removal.
Journal ArticleDOI
Two different pathways for D-xylose metabolism and the effect of xylose concentration on the yield coefficient of L-lactate in mixed-acid fermentation by the lactic acid bacterium Lactococcus lactis IO-1.
TL;DR: The results indicate that in L. lactis IO-1 xylose, the bacterium may be catabolized by two different pathways, the phosphoketolase pathway yielding acetate, formate and ethanol, and the pentose phosphate (PP)/glycolytic pathway which convertsxylose to L-lactate only.

Process considerations in the enzymatic hydrolysis of biomass
TL;DR: The processes by which cellulases hydrolyse cellulose are a function of substrate reactivity as well as enzyme activity, and the two must be considered together if an accurate description of biomass saccharification is to be developed as discussed by the authors.

Function of reduced pyridine nucleotide-ferredoxin oxidoreductases in saccharolytic Clostridia
TL;DR: In the two clostridia all catabolic oxidations-reductions are specific for NAD(H) and that the usual NADPH-producing processes such as the glucose 6-phosphate dehydrogenase or malate enzyme reactions are absent.

Biochemical fuel cell utilizing immobilized cells of clostridium butyricum
TL;DR: In this article, the authors applied the hydrogenase system of a microbial cell to the anodic reaction of a biochemical fuel cell and reported the production of hydrogen from glucose by Clostridium butyricum.
