Bacillus vietnamensis sp. nov., a moderately halotolerant, aerobic, endospore-forming bacterium isolated from Vietnamese fish sauce

Five strains of Gram-positive, endospore-forming, moderately halotolerant bacteria were studied taxonomically. Four were isolated from Vietnamese fish sauce and one from the Gulf of Mexico. Phylogenetic analysis based on 16S rRNA gene sequences showed that these strains clustered within the radiatio...

Zusammenfassung:	Five strains of Gram-positive, endospore-forming, moderately halotolerant bacteria were studied taxonomically. Four were isolated from Vietnamese fish sauce and one from the Gulf of Mexico. Phylogenetic analysis based on 16S rRNA gene sequences showed that these strains clustered within the radiation of the genus Bacillus but separately from recognized Bacillus species. DNA G+C composition of the isolates ranged from 43 to 44 mol%. Strains 15-1T and NRRL B-14850 showed high levels of DNA-DNA relatedness (82-100 %) to each other and to the other strains isolated here; they displayed low levels of DNA-DNA relatedness (
