Abstract

The Gram-stain-negative, aerobic, non-motile, oxidase- and catalase-positive, rod-shaped yellow-coloured bacterial strain MG-N-17 was isolated from a water sample of Lake Fertő/Neusiedler See (Hungary). Results of phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain forms a distinct linage within the family of the phylum , and its closest relatives are DSM 4136 (94.38 %) and DC2a-G7 (91.55 %). The novel bacterial strain prefers a weak alkaline environment and grows optimally between 22–28 °C in the absence of NaCl. The major isoprenoid quinones are MK-10, MK-11, MK-12 and MK-9. The major cellular fatty acids are anteiso-C, C, Cω5 and iso-C. The polar lipid profile contains phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids and four unidentified glycolipids. The assembled draft genome of strain MG-N-17 had 44 contigs with an N50 value 348255 nt, 56.5× genome coverage, total length of 5 910 933 bp and G+C content of 56.9 mol%. Strain MG-N-17 (=DSM 106674=NCAIM B.02643) is proposed as the type strain of a new genus and species in the family , for which the name gen. nov., sp. nov. is proposed.
