Abstract

A rod shaped, Gram-stain positive, non-motile, facultative anaerobic and gelatin hydrolysing bacterium, strain PG1T, was isolated from reclaimed land soil in Kyehwa-do, Republic of Korea. Strain PG1T showed highest 16S rRNA gene sequence similarity (97.4 and 96.5 %, respectively) to Paenibacillus shenyangensis A9T and Paenibacillus hunanensis FeL05T, and clustered closely with the members of the family Paenibacillaceae. DNA–DNA hybridization studies revealed a genomic relatedness of 47 ± 9 % with P. shenyangensis A9T. The predominant fatty acids of strain PG1T were identified to be anteiso-C15:0 (46.7 %) and C16:0 (22.7 %). Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid were found to be the major polar lipids. The genomic DNA G+C content was found to be 47.7 mol%. This polyphasic characterisation of the newly isolated strain PG1T justifies its description as representative of a novel species in the genus Paenibacillus, for which the name Paenibacillus gelatinilyticus sp. nov., (type strain = PG1T = KCTC 33642T = JCM 30624T) is proposed.
