ABSTRACT
An aerobic, Gram-stain-positive, endospore-forming, rod-shaped and moderately halophilic strain SKP4-6T, was isolated from shrimp paste (Ka-pi) collected from Samut Sakhon Province, Thailand. Phylogenetic analysis revealed that strain SKP4-6T belonged to the genus Halobacillus and was most closely related to Halobacillus salinus JCM 11546T (98.6â%), Halobacillus locisalis KCTC 3788T (98.6â%) and Halobacillus yeomjeoni KCTC 3957T (98.6â%) based on 16S rRNA gene sequence similarity. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain SKP4-6T and its related species were 18.2-19.3â% and 69.84-84.51â%, respectively, which were lower than the threshold recommended for species delineation. The strain grew optimally at 30-40 °C, at pH 7.0 and with 10-15â% (w/v) NaCl. It contained l-Orn-d-Asp in the cell wall peptidoglycan. The DNA G+C content was 44.8 mol%. The major fatty acids were iso-C15ââ0, anteiso-C15ââ0 and anteiso-C17ââ0. The predominant isoprenoid quinone was MK-7. Phosphatidylglycerol and diphosphatidylglycerol were present as major polar lipids. Based on this polyphasic approach, digital DNA-DNA relatedness and ANI values, strain SKP4-6T represents a novel species of the genus Halobacillus, for which the name Halobacillus fulvus sp. nov. is proposed. The type strain is SKP4-6T (=JCM 32624T=TISTR 2595T).
