Physical degradation of lignified stem tissues by ruminal fungi.

Ruminal bacteria or fungi were selected by the addition of cycloheximide or streptomycin and penicillin, respectively, to ruminal fluid, and the weakening and degradation of lignified tissues in alfalfa and Bermuda grass stems by these treatments and whole ruminal fluid were evaluated in vitro. Dry weight loss in alfalfa was similar for whole ruminal fluid and streptomycin-penicillin treatment,...

Antibiosis between ruminal bacteria and ruminal fungi.

Cellulose digestion, bacterial numbers, and fungal numbers were monitored over time in vitro by using a purified cellulose medium with and without antibiotics (penicillin and streptomycin). All fermentations were inoculated with a 1:10 dilution of whole rumen contents (WRC). Without antibiotics, cellulose digestion was higher (P < 0.01) at 24, 30, 48, and 72 h; fungi had almost disappeared by 2...

Plant Polysaccharide Degradation by Fungi

Plant biomass is the major carbon source for many fungal species. Due to its complex polymeric nature, degradation of this biomass to digestible monomers requires a large range of enzyme activities. With the availability of an increasing number of fungal genomes, new insights into the diversity of fungi with respect to plant biomass degradation have been obtained. Recent progress in this area w...

Ruminal Degradation Kinetics of Wheat Straw Irradiated by High Doses of Electron Beam

This study was conducted to evaluate the effect of electron beam irradiation at doses of 250 and 500 kGy on the chemical composition and ruminal dry matter (DM) and neutral detergent fiber (NDF) degradability of wheat straw. Nylon bags of untreated or irradiated wheat straw were suspended in the rumen of three rams for up to 72 h, and resulting data were fitted to non-linear degradation model t...

Mechanisms of degradation by white rot fungi.

White rot fungi use a variety of mechanisms to accomplish the complete degradation of lignin and a wide variety of environmental pollutants. Both oxidative and reductive reactions are required for the metabolism of both lignin and environmental pollutants. The fungi secrete a family of peroxidases to catalyze both direct and indirect oxidation of chemicals. The peroxidases can also catalyze red...
