Description of six novel species sp. nov., sp. nov., sp. nov., sp. nov., sp. nov. and sp. nov., isolated from mangrove ecosystem.

Six Gram-stain-positive and rod-shaped strains, designated FJAT-51614, FJAT-51639, FJAT-52054, FJAT-52991, FJAT-53654 and FJAT-53711, 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 , and . Menaquinone MK-7 (100%) was present in all strains except strain FJAT-51614, which contained MK-7 (32%) and MK-8 (68%). The major fatty acids (>10%) in strains FJAT-52054 and FJAT-51614 were anteiso-C and iso-C. The major fatty acid (>10%) in strain FJAT-53654 was anteiso-C, while in strain FJAT-51639 were iso-C and iso-C. The major fatty acids in strains FJAT-52991 and FJAT-53711 were iso-C and iso-C. The major polar lipids in strains FJAT-51639, FJAT-52991 and FJAT-51614 were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, while strains FJAT-53711, FJAT-52054 and FJAT-53654 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 sp. nov. (FJAT-51639=GDMCC 1.3073=JCM 35615), sp. nov. (FJAT-52991=GDMCC 1.3069=JCM 35619), sp. nov. (FJAT-53711=GDMCC 1.3068=JCM 35616), sp. nov. (FJAT-53654=GDMCC 1.3075=JCM 35614), sp. nov. (FJAT-52054=GDMCC 1.3074=JCM 35620) and sp. nov. (FJAT-51614=GDMCC 1.3072=JCM35478) are proposed.
