PURPOSE:To efficiently improve environmental hygiene by searching for and separating a microorganism capable of decomposing fish scale collagen from soil. CONSTITUTION:A strain separated from soil is purified and subsequently cultured in a liquid culture medium containing sterilized fish scales to afford a culture. A strain having fish collagen decomposing activity is then screened from the resultant culture to afford Xanthomonas albilineans SC-001 strain having the following aerobic bacteriological properties. Morphological findings; Gram-negative bacillus of 0.4 to 0.6X0.9 to 1.2mum size in a single cell or straight- chain form having polar flagella by culturing at 37 deg.C for 24hr. Culture findings; circular, smooth and red colonies by culturing at 37 deg.C for 24hr in a bouillon, agar plate culture medium without growing in a glucose agar culture medium. Physiological findings; reducing ability of nitrates; negative, urease; negative and catalase; positive. Growth range; pH 6-10. Optimum temperature; 37 deg.C. Utilizing glucose without utilizing lactose. Chemical properties; 64.5mol% content of guanine, cytosine, etc. |
