Abstract:
A thermophilic, alkaliphilic and catalase-positive bacterium, designated strain HA6 T , was isolated from a hot spring in China. The strain was aerobic and chemo-organotrophic and grew optimally at 60 °C, pH 8.5 and 1.5 % (w/v) NaCl. The cells were Gram-positive rods, forming single terminal endospores. The predominant cellular fatty acids were iso-C 15 : 0 and iso-C 17 : 0 . The cell-wall peptidoglycan contained meso -diaminopimelic acid. The genomic DNA G+C content was 45.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain HA6 T formed a distinct lineage within the family Bacillaceae and was most closely related to Bacillus horti K13 T and Bacillus smithii DSM 4216 T , with sequence similarities of 91.8 and 93.1 %, respectively. On the basis of its physiological and molecular properties, strain HA6 T should be placed in a novel genus and species, for which the name Caldalkalibacillus thermarum gen. nov., sp. nov. is proposed. The type strain of Caldalkalibacillus thermarum is strain HA6 T (=CGMCC 1.4242 T =JCM 13486 T ).
