ABSTRACT
Real-time PCR was conducted to quantify methanogens, bacteria, Fibrobacter succinogenes, Ruminococcus flavefaciens and fungi in rumen fluid incubated in vitro when methane synthesis was inhibited. After 24 h incubation, methanogens in sodium salt of 2-bromoethanesulphonic acid (BES)-added fluids was reduced to 10.4% of control (P<0.01). BES did not significantly influence the number of bacteria and R. flavefaciens. However, the number of F. succinogenes in BES-treated fluid was 50.0% higher than in control (P<0.01). Population density of fungi fell by 61.9% (P<0.01) in comparison with control. Addition with BES changed the rumen microbiota and had a varying influence on different microbes.
