Acidogenic fermentation of lignocellulose–acid yield and conversion of components
TLDR
In this article, a mixed culture of anaerobic microorganisms was used to ferment corn stover to form simple (C2-C6), volatile organic acids, and the yield of acid with respect to material fermented was 84%.Abstract:
Corn stover was fermented with a mixed culture of anaerobic microorganisms to form simple (C2-C6), volatile organic acids. Alkaline pretreatment allowed a greater fermentation of the pectin and hemicellulose than of the cellulose and lignin, but all components were utilized. The percent fermentation of the soluble fraction, hemicellulose, cellulose, and lignin was 79.6, 74.1, 36.9, and 20.9%, respively. The yield of acid (as acetate) with respect to material fermented was 84%.read more

Acidogenic fermentation of corn stover
TL;DR: The data show that acidogenic fermentation can produce useful volatile fatty acids in high yields from a complex lignocellulosic feedstock and could be useful in converting biomass to chemical feedstocks and fuel.

The Maceration of Linen Flax under Anaerobic Conditions
TL;DR: Fractionation and analysis of straw samples showed that 83% of pectic polyuronide present at the start of the ret was degraded by 70 h, whereas 16% of the hemicellulose and none of the cellulose was lost over the same period.

Attack on lignified grass cell walls by a facultatively anaerobic bacterium.
TL;DR: The filamentous, facultatively anaerobic microorganism, designated 7-1, demonstrated various colony and cellular morphologies under different growth conditions; the phenolic acids sinapic, ferulic, and p-coumaric acids as substrates for growth were used more effectively.
