Abstract
Six Gram-stain-positive and rod-shaped strains, designated FJAT-51614T, FJAT-51639T, FJAT-52054T, FJAT-52991T, FJAT-53654T and FJAT-53711T, were isolated from a mangrove ecosystem. The condition for growth among the strains varied (pH ranging 5.0-11.0 and temperature 15-45 °C). These strains showed the highest 16S rRNA gene sequence similarity to the genera Bacillus, Metabacillus and Psychrobacillus. Menaquinone MK-7 (100%) was present in all strains except strain FJAT-51614T, which contained MK-7 (32%) and MK-8 (68%). The major fatty acids (>10%) in strains FJAT-52054T and FJAT-51614T were anteiso-C15 : 0 and iso-C14 : 0. The major fatty acid (>10%) in strain FJAT-53654T was anteiso-C15 : 0, while in strain FJAT-51639T were iso-C15 : 0 and iso-C17 : 0. The major fatty acids in strains FJAT-52991T and FJAT-53711T were iso-C15 : 0 and iso-C16 : 0. The major polar lipids in strains FJAT-51639T, FJAT-52991T and FJAT-51614T were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, while strains FJAT-53711T, FJAT-52054T and FJAT-53654T consist of diphosphatidylglycerol and phosphatidylglycerol. The genome-relatedness values among the present study strains and the closest species were below the recognized cutoff levels for species delineation. The polyphasic analysis comparison results represent six strains as novel species for which the names Bacillus bruguierae sp. nov. (FJAT-51639T=GDMCC 1.3073T=JCM 35615T), Bacillus kandeliae sp. nov. (FJAT-52991T=GDMCC 1.3069T=JCM 35619T), Bacillus yunxiaonensis sp. nov. (FJAT-53711T=GDMCC 1.3068T=JCM 35616T), Metabacillus rhizosphaerae sp. nov. (FJAT-53654T=GDMCC 1.3075T=JCM 35614T), Metabacillus sediminis sp. nov. (FJAT-52054T=GDMCC 1.3074T=JCM 35620T) and Psychrobacillus mangrovi sp. nov. (FJAT-51614T=GDMCC 1.3072T=JCM35478T) are proposed.
期刊介绍:
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
