Isolation and fermentation characteristics of strains of Butyrivibrio from ruminal ingesta.

Fermentation of xylans by Butyrivibrio fibrisolvens and other ruminal bacteria.

The ability of Butyrivibrio fibrisolvens and other ruminal bacteria (6 species, 18 strains) to ferment a crude xylan from wheat straw or to ferment xylans from larchwood or oat spelts was studied. Liquid cultures were monitored for carbohydrate utilization, cell growth (protein), and fermentation acid production. B. fibrisolvens 49, H17c, AcTF2, and D1 grew almost as well on one or more of the ...

Effects of Ruminal Infusion of Garlic Oil on Fermentation Dynamics, Fatty Acid Profile and Abundance of Bacteria Involved in Biohydrogenation in Rumen of Goats

This study aimed to investigate the effects of ruminal infusion of garlic oil (GO) on fermentation dynamics, fatty acid (FA) profile, and abundance of bacteria involved in biohydrogenation in the rumen. Six wethers fitted with ruminal fistula were assigned to two groups for cross-over design with a 14-d interval. Each 30-d experimental period consisted of a 27-d adaptation and a 3-d sample coll...

Effects of Thyme Essential Oil and Disodium Fumarate on Ruminal Fermentation Characteristics, Microbial Population and Nutrient Flow in a Dual Flow Continuous Culture System

The aim of the present study was to investigate the effects of di-sodium fumarate (DSF) and thyme essential oil (TEO) solely and simultaneously on ruminal fermentation properties and microbial abundance. A dual-flow continuous culture system (DFCC) with eight 1400-mL fermenters was used in a period of 12 d that divided to 9 d for adaptation and 3 d for sampling. Fermenters were fed 100 g d...

Isolation and carbohydrate fermentation tests of Mycoplasma agalactiae and Myeoplasma mycoides subsp.mycoides strains in Iran

Ruminal Methane Emission, Microbial Population and Fermentation Characteristics in Sheep as Affected by Malva sylvestris Leaf Extract: in vitro Study

The objective of this study was to investigate in vitro effect of Malva sylvestris leaf extract (at 0, 25, 50 and 100 µL/30 mL of medium) on sheep ruminal cellulolytic and total viable bacteria growth, protozoa populations, methane production, neutral detergent fiber degradability (NDFD) and fermentation efficiency of oat hay. The addition of Malva sylvestris leaf extract at 25, 50 and 100 µL l...
