一株中度嗜盐菌新种LYG2#的分离与鉴定
Isolation and Identification of a Moderately Halophilic Bacterium LYG2#
摘要
Abstract
[Objective] To identify a strain LYG2# isolated from Lianyungang Qingkou Salinas.[Method] We identified the strain LYG2# by means of 16S rRNA gene sequence blast,phylogenetic analysis and the determination of physiological and biochemical characteristics.[Result] The bacteria was gram negative,appeared pink and round colony.Strain LYG2# was spiral,the length of the bacteria was from 1.50 to 2.00 μm,and the width was 0.24 μm.The optimum salt concentration,temperature and pH were 9.6%,32℃ and 8.5.By 16S rRNA gene sequence blast,the 16S rDNA of the strain LYG2# and Spiribacter salinus M19-40T showed the highest similarity,was 95.98%.Strain LYG2# was preserved at China General Microbiological Culture Collection Center,the number was CGMCC 1.12136,the GenBank accession number for 16S rDNA of the strain was JQ087461.[Conclusion] The bacteria isolated was a moderately halophilic bacterium,and was a new species of the Spiribacter genus.关键词
