Sediment and plant decomposed soil were collected from Bhitarkanika National Park. Soil samples were kept in 70 ํ C to eradicate the moisture. One gram of each soil sample was transferred to aliquot of 9 mL sterle distilled water by vortex mixture at constant speed 4000 rpm for 15min. The soil suspension was inoculated in ISP-2 Medium (Yeast extract: 4g/L, Malt extract powder: 10g/L, Glucose: 4g/L, Agar: 18g/L) in appropriate plate in duplicate. The plates were incubated for 7 days at 28 ํ C . Pure culture actinomycetes strains are stored in ISP-2 medium at 4 ํ C and Glycerol stock was prepred for future use.
Actinomycetes strains were screened for their ability to produce the hydrolytic enzymes: cellulase in a plate assay method using 1% carboxymethyl ccellulase in a basal salt media,respectively, according to [18] at the incubation period, 0.1% Congo red solution was added and counterstained with 1M NaCl for 15-20min. The zone of cellulose hydrolysis was appeared as a clear area around the colony.
