    摘要:Summary
    A Gram-positive, motile, endospore-forming, irregular rod 0.7-0.9 x 2.5-5.0 μm, halophilic bacterial strain, NTU-101T was isolated from Chigu saltern, previously salt production field in southern Taiwan. The isolate was characterized taxonomically based on biochemical and molecular approaches. It grows optimally at 40°C and in the presence of 5-10 % NaCl. Strain NTU-101T had cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-7 as the predominant menaquinone. Major polar lipids are phosphatidylglycerol, diphosphatidylglycerol and phosphatidylethanolamine. Anteiso-C15:0, Iso-C15:0 and Anteiso-C17:0 as major fatty acids. The DNA G+C content was 37.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed its affiliation to the genus Virgibacillus. DNA-DNA relatedness values between strain NTU-101T and Virgibacillus dokdonensis, and Virgibacillus pantothenticus were 17.5% and 21.5%, respectively. Based on the phenotypic and phylogenetic properties, strain NTU-101T (=BCRC 17637T=CGMCC 1.6496T) was classified as novel strain of Virgibacillus species, for which the name Virgibacillus chiguensis sp. nov. is proposed.
