Paenibacillus sp. CMAA1364 Genome sequencing

The bacterial strain CMAA 1364^T, isolated from a rock surface in Admiralty Bay, Antarctic Peninsula, was identified as a new species within the Paenibacillus tibetensis subclade using a polyphasic taxonomic approach. Phylogenetic analysis showed high similarity to Paenibacillus macquariensis and Paenibacillus antarcticus, while chemotaxonomic analysis revealed a profile typical of Paenibacillus species, including MK-7 menaquinone and specific fatty acids. This psychrotolerant strain, growing at 4-37 C, displayed unique characteristics distinguishing it from close relatives, leading to its classification as Paenibacillus seldinae sp. nov., with CMAA 1364^T as the type strain (DSM 104510^T = NRRL B-65466^T).
