Abstract
A bacterium producing the extracellular xylanase and CMCase was isolated from soil and has been identified as Bacillus sp. The isolate, named Bacillus sp. A-7, was shown to be very similar to Bacillus licheniformis on the basis of its biochemical and physiological properties. The maximum xylanase and CMCase production were obtained when 2.0% (w/v) glucose and 0.3% (w/v) yeast extract were used as carbon source and nitrogen source, respectively. The best mineral conditions for xylanase and CMCase production were 0.1%(w/v) $CaC1_2$. Among the various feedstuffs, 1.0%(w/v) soybean meal was selected for the best xylanase and CMCase production.
