Abstract

|
|
|
A bacterial strain BS-214 producing extracellular pectinase was isolated from soil. The isolated bacterium was identified as a strain of Bacillus so. based on the morphological, biochemical, and physiological characteristics. Cell growth and pectinase activity of Bacillus sp. BS-214 were reached to a mixium in the culture condition of pH 8.5 at 40℃. Production of pectinase by the strain was the highest when polygalacturonic acid was added to culture medium as a carbon source, and its optimal concentration was 1%. Also, yeast extract was used as the best nitrogen source for the production of pectinase by the concentration of 0.25%. Decomposition of a constituent of Edzeworthia papyrifera by the strain was observed by scanning electron microscope.
