Hydrogen production by fermentative consortia
TL;DR: The different methods used to inhibit the H2-consuming bacteria are analyzed, such as biokinetic control, heat-shock treatment and chemical inhibitors along with their advantages/disadvantages for their application on an industrial scale.

Effects of exogenous fibrolytic enzymes on in vitro ruminal fermentation of substrates with different forage:concentrate ratios
TL;DR: In this article, the effects of three fibrolytic enzymes (xylanase from Trichoderma viride (XYL), endoglucanase from Aspergillus niger (ASP) and Trichodorma longibrachiatum (TR)) on the fermentation of three substrates composed of grass hay:

Influence and strategies for enhanced biohydrogen production from food waste
TL;DR: In this paper, the authors have shown that the use of nanoparticles in fermentation process along with the application of short and cyclic ultrasound is beneficial to increase the process efficiency and the augmentation in ultrasound-assisted process is due to the physical and chemical effects of ultrasound in the medium through the phenomenon of cavitation.

Development and evaluation of empirical equations to predict feed passage rate in cattle
TL;DR: In this paper, a random coefficients model that used each study effect as a random variable was used to select statistically significant input variables to predict rate of passage for all classes of dairy and beef cattle.

Effects of solids and liquid flows on fermentation in continuous cultures. II. Nitrogen partition and efficiency of microbial synthesis.
TL;DR: The effects of varying solids retention time (SRT) and liquid dilution rate (D) on N partition and microbial efficiency were studied in vitro with a dual flow continuous culture system and responses were variable.

Preliminary Observations on the Relationship between Gas Production and Microbial Protein Synthesis in Vitro
TL;DR: The data indicate that the type of carbohydrate and the rate of carbohydrate fermentation influence microbial protein synthesis per unit volume of gas produced, but the relationship between total synthesis and cumulative gas production with carbohydrate mixture as the substrate was linear.
Journal ArticleDOI
A simple continuous culture system for rumen microbial digestion study and effects of defaunation and dilution rates.
TL;DR: Dry matter and cellulose digestibilities and VFA production were depressed by defaunation, and the depressions were more pronounced at higher dilution rates, suggesting a favorable effect of protozoa on rumen microbial digestion in higher producing animals.

Evaluation of a method of measuring fermentation rates and net growth of rumen microorganisms.
Manal Zaki el-Din,K. El-Shazly +1 more
TL;DR: During in vitro incubation of whole ruminal contents, there was a highly significant correlation between the net growth rate values (obtained by using fermentation capacity as an index) and the change in concentration of viable rumen bacteria or total ciliate protozoa.
