| dc.description | In order to obtain cellulases that improve the detergency of laundry detergent products, two alkalophilic microorganims, Bacillus sp B38-2 and Streptomyces sp S36-2, were isolated from soil and compost by incubating samples in enrichment culture medium containing CMC and Na2CO3 at pH9.6. It was found that they secrete a constitutive extracellular alkaline carboxymethyl cellulase (CMCase) in high quantity. The maximum enzyme activity was observed between 48hr to 72 hr at 30-degrees-C for the Streptomyces and between 72hr to 96hr at 35-degrees-C for the Bacillus. The optimum pH and temperature of the crude enzyme activities ranged from 6.0 to 7.0 at 55-degrees-C for the Streptomyces and 7.0 to 8.0 at 60-degrees-C for the Bacillus. Two crude CMCases activities were termostable at 45-degrees-C for 1hr and the both crude enzyme activities of the Bacillus as of the Streptomyces were stable at pH 5.0 to 9.0 after pH treatments in various buffer solutions at 30-degrees-C for 24hr. | |
