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.

Efficiency of rumen microbial growth: influence of some theoretical and experimental factors of YATP.
R.B. Hespell,Marvin P. Bryant +1 more
TL;DR: The data from nutrient-limited continuous culture (chemostat) studies of single or mixed species indicate rumen bacteria have the potential for a low growth maintenance requirement and high cell yields, but cell yields become progressively lower with decreasing growth rate, increasing Me, or both as a greater proport ion of the ATP produced is diverted to maintenance functions.
Journal ArticleDOI
Hydrogen as an intermediate in the rumen fermentation.
TL;DR: It is concluded that hydrogen is a very important intermediate in the rumen production of methane because it correlated more closely with concentration of dissolved hydrogen than with formate.

Interactions between substrate, fermentation end-products, buffering systems and gas production upon fermentation of different carbohydrates by mixed rumen microorganisms in vitro
J. M. W. Beuvink,S. F. Spoelstra +1 more
TL;DR: In this article, the relationship between direct and indirect gas production in relation to fermentation kinetics was studied by incubating glucose, rice starch and cellulose, and the total amount of gas formed was found to be dependent on the composition of the fermentation end-products formed.

Comparison of Maintenance Energy Expenditures and Growth Yields Among Several Rumen Bacteria Grown on Continuous Culture
J B Russell,R.L. Baldwin +1 more
TL;DR: Results showed that relative yield among the bacteria was growth rate dependent, and it is made that maintenance requirements could be a significant determinant of bacterial competition in the rumen.
