Abstract

Bacterial strains MCy10943 and MCy10944 were isolated in 2014 from dried Nepalese soil samples collected in 2013 from Phukot, Kalikot, Western Nepal, and Godawari, Lalitpur, Central Nepal. The novel organisms showed typical myxobacterial growth characteristics, which include swarming colony and fruiting body formation on solid surfaces, and a predatory ability to lyse micro-organisms. The strains were aerobic, mesophilic, chemoheterotrophic and showed resistance to various antibiotics. The major cellular fatty acids common to both organisms were C 2-OH, iso-C, C and iso-C. The G+C content of the genomic DNA was 72–75 mol%. Phylogenetic analysis showed that the strains belong to the family , suborder , order . The 16S rRNA gene sequences of both strains showed 97–98 % similarity to DSM 2261 and DSM 14727, and 96.7–97 % to DSM 2262 and DSM 52716. Polyphasic taxonomic characterization suggested that strains MCy10943 and MCy10944 represent two distinct species of a new genus, for which the names gen. nov., sp. nov. and sp. nov. are proposed. The type strain of is MCy10943 (=DSM 102952=NCCB 100600) while that for is MCy10944 (=DSM 102953=NCCB 100601). In addition, emended descriptions of the genera and , and of the family are provided.
