Lacihabitans lacunae sp. nov., isolated from a lagoon.

A non-motile, orange-pigmented bacterium, designated strain HME7103T, was isolated from lagoon water in the Republic of Korea. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME7103T formed a lineage within the genus Lacihabitans and family Cytophagaceae. Strain HME7103T was closely related to Lacihabitans soyangensis HME6675T (95.7 % 16S rRNA gene sequence similarity). The major fatty acids of strain HME7103T were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and iso-C15 : 0. The major respiratory quinone was MK-7. The major polyamine was spermidine. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids, one unidentified aminophospholipid and three unidentified polar lipids. The DNA G+C content of strain HME7103T was 40.6 mol%. On the basis of the evidence presented in this study, strain HME7103T represents a novel species within the genus Lacihabitans, for which the name Lacihabitans lacunae sp. nov. is proposed. The type strain is HME7103T (=KCTC 23619T=CECT 7956T).
