一株菌红素产生菌的鉴定及色素组分分析

对分离自腌鱼的高产菌红素(bacterioruberin)的菌株r-fish进行了形态特征、生理生化特性与细胞化学组分的分析以及基于16SrDNA序列的系统发育分析。形态特征、生理生化特性及细胞化学组分的分析结果表明菌株r-fish为球形的嗜盐古菌。基于16SrDNA序列的系统发育结果表明，r-fish与Halobacterium trapanicum NCIMB784菌株的相似性为99．8％，归入Na-trinema属。用TLC法对r-fish的色素进行了分析，r-fish的色素组分包括菌红素(bacteriorubefin)、脱水菌红素(anhydrobacteriorubefin)、双脱水菌红素(bisanhydrobacteriorubeftn)和一未知色素。与Halobacteriumhalobium和Halococcus morrhuae的色素组分相似。

Identification of a bacterioruberin-producing microorganism and analysis of its pigment

A strain r-fish that produces red pigments was isolated from salted fish.Based on its morphological,cultural,physiological and biochemical characteristics,strain r-fish is certainly an coccoid extremely halophilic archaeon.Phylogenetic analysis results indicate that r-fish and Halobacterium trapanicum NCIMB784both belong to the genus of Natrinema at the similarity of99.8%.The red pigments of r-fish were isolated and subjected to TLC analysis.The red pigments of r-fish contained,bacterioruberin,anhydrobacterioruberin,bisanhydrobacterioruberin and an unidentified pigment,similar to the pigment compositions of Halobacterium halobium and Halococcus morrhuae.
