| Abstract |
A piezotolerant, mesophilic, marine lactic acid bacterium (strain LT20T) was isolated from a deep sub-seafloor sediment core collected at Nankai Trough, off the coast of Japan. Cells were Gram-positive, rod-shaped, non-sporulating and non-motile. The NaCl concentration range for growth was 0-120 g l(-1), with the optimum at 10-20 g l(-1). The temperature range for growth at pH 7.0 was 4-50 degrees C, with the optimum at 37-40 degrees C. The optimum pH for growth was 7.0-8.0. The optimum pressure for growth was 0.1 MPa with tolerance up to 30 MPa. The main cellular phospholipids were phosphatidylglycerols (25 %), diphosphatidylglycerols (34 %) and a group of compounds tentatively identified as ammonium-containing phosphatidylserines (32 %); phosphatidylethanolamines (9 %) were minor components. The fatty acid composition was dominated by side chains of 16 : 0, 14 : 0 and 16 : 1. The G+C content of the genomic DNA was 42 mol%. On the basis of 16S rRNA gene sequence analysis and the secondary structure of the V6 region, this organism was found to belong to the genus Marinilactibacillus and was closely related to Marinilactibacillus psychrotolerans M13-2(T) (99 %), Marinilactibacillus sp. strain MJYP.25.24 (99 %) and Alkalibacterium olivapovliticus strain ww2-SN4C (97 %). Despite the high similarity between their 16S rRNA gene sequences (99 %), the DNA-DNA hybridization levels were less than 20 %. On the basis of physiological and genetic characteristics, it is proposed that this organism be classified as a novel species, Marinilactibacillus piezotolerans sp. nov. The type strain is LT20T (=DSM 16108T=JCM 12337T). |
