Expertise and Research Interests

My current research interests all:rumen and gastrointestinal microbial ecology of animals;metabolism of benzenoid compounds by intestinal bacteria (i.e. phenolics and indolic);the significance of bacteriophages in the rumen ecosystem;ruminal and gastrointestinal microbial degradation of chitin;microbial interaction in the degradation of fiberous feeds and agri-residues;chemical treatment of recalcitrant feeds on the efficiency of ruminal fermentation;use of microbial processes for the production of supplemental feeds for livestock;antimicrobial properties of lactobacilli in cultured dairy foods especially gangliosides;mechanism of growth promotion induced by dietary antibiotics to young animals;probiotics in the diet of young livestock;inhibition of urease activity;microbiological control of animal waste odor;ozonation of livestock waste to reduce environmental pollution;microbial inoculants for ensiled feeds particularly lactobacilli and propionibacterium;microbial phytase for improving phytate phosphorous utilization;ruminal degradation of mycotoxins in feeds particularly DON;enteropathogenic bacteria involved in animal product contamination.
