Abstract
|
|
|
|
A bacterial strain, JE-34, producing a high concentration of red pigment was isolated from a sediment in East China Sea. It was identified as Zooshikella sp. JE-34 based on the 16S rRNA gene sequence analysis. The red pigment was purified by solvent extraction and HPLC was identified as prodigiosin-like compound. Nutritional and cultural conditions were optimized for the production of prodigiosin-like pigment in the flask level. Optimal culture conditions were at initial medium pH 6.0~7.0, 30oC and 4 days incubation. For carbon and, nitrogen sources were soluble starch and malt extract.
