Improving Butanol Fermentation To Enter the Advanced Biofuel Market [PDF]

mBio, 2012
ABSTRACT 1-Butanol is a large-volume, intermediate chemical with favorable physical and chemical properties for blending with or directly substituting for gasoline. The per-volume value of butanol, as a chemical, is sufficient for investing into the recommercialization of the classical acetone-butanol-ethanol (ABE) (E. M.

Effect of Racephenicol on Antibiotic Resistance of Lactose-Fermenting Enteric Bacteria in Chickens [PDF]

Antimicrobial Agents and Chemotherapy, 1973
The incidence of lactose-fermenting enteric organisms resistant to chloramphenicol increased from less than 0.1% prior to treatment to more than 90% in two groups of chickens fed racephenicol-supplemented feed at 50 or 140 g/ton for 10 days, whereas controls remained unchanged.

Physiological responses and adaptations to high methane production in Japanese Black cattle

Scientific Reports, 2022
In this study, using enteric methane emissions, we investigated the metabolic characteristics of Japanese Black cattle. Their methane emissions were measured at early (age 13 months), middle (20 months), and late fattening phases (28 months). Cattle with
