Abstract: Total 54 bacterial isolates were obtained from the rumen of migratory goats of Himachal Pradesh. However, two isolates (CDB 2 and CDB 4) showed maximum enzymatic activity. The isolate CDB 2 showed maximum enzymatic activity at pH 7.0, temperature 40°C, incubation time 96h and yeast extract as the nitrogen source, whereas, isolate CDB 4 showed maximum activity at pH 7.0, temperature 50°C, incubation time 96h and peptone as the nitrogen source. The isolate CDB 2 was identified as Megasphaera species and CDB 4 as Prevotella species on the basis of Bergey’s manual of systematic classification.

INTRODUCTION
Cellulose is the most abundant biopolymer in nature and constitutes a large pool of carbon source for the microorganisms which are responsible for the decomposition of organic matter in soil (Shanker et al., 2011). Cellulose degradation and its subsequent utilizations are important aspect for global carbon sources. The value of cellulose as a renewable energy source has made hydrolysis of this compound as a subject for intense research and industrial interest (Bhat et al., 2000).
The rumen is a unique natural habitat for different microorganisms (bacteria, fungi, protozoans) that has evolved into a complex and efficient system. To degrade cellulose ruminants mostly depend on microorganism but very few species can degrade cellulose (Bryant, 1973). To isolate fibrolytic bacteria and identify their lignocelluloses degrading enzyme system from the rumen of variety of herbivores, considerable efforts have been made over past few decades (Flint et al., 2008; Sharma et al., 2017b).
