Isolation and Identification of Bacterium Degrading the Cellulose in Rrumen of Sheep and Cloning of CelB Gene in R.albus.;

The results showed that the killing rates of Escherichia coli in suspension exposed to the stock solution of garlic solution with vinegar for 10 min,Staphylococcus aureus exposed for 15 min and Candida albicans exposed for 25 min were 100%.

5%(v/v) solution of the lotion had good efficacy in inhibiting Escherichia coli, Candida albicans and Neisseria gonorrhoeae.

Results 5% (v/v) solution of the extract had good efficacy in inhibiting Escherichia coli and Candida albicans.

Use of rpoB and 16S rDNA genes to analyze rumen bacterial diversity of goat using PCR and DGGE;

Isolation of Twelve Strains of Rumen Bacteria and Effect of Propionibacterium Acnes on the Fermentation of Rumen Microorganism;

Objective:To investigate the change of rumen bacteria floras after diets of beef cattle supplemented with 2% fish oil.

The effects of different dietary ratio of concentrate to roughage on rumen fungi growth and fermentation parameters using dual effluent continuous culture system;

In vitro fermentation techniques were used to investigate the attachment on rice straw and fermentation profiles of different concentrate to crude ratio substrates by rumen fungi.

Relatively, rumen fungi had a less number and slower growth rate compared with rumen bacteria.

When changing the ecological factors as temperature, stirring intensity and C /N proportion, this papercarried out the continuous fermination experiment of ruminal microbial flora in an artificial rumen equipment,determinded the rumen bacteria number and VFA output daily, and analyzed the interrelation and regression between thenumber of bacteria and VFA yield.
