Zophobihabitans entericus gen. nov., sp. nov., a new member of the family Orbaceae isolated from the gut of a superworm Zophobas morio.

2021 
A novel bacterial strain, designated IPMB12T, isolated from the gut of the superworm Zophobas morio in Taiwan, was characterized using a polyphasic taxonomic approach. Cells were Gram-stain-negative, facultatively anaerobic, non-motile, coccoid or rod-shaped and formed translucent colonies. Optimal growth occurred at 25-37 °C, pH 9-10, and with 0-2 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences and coding sequences of 92 protein clusters indicated that strain IPMB12T is affiliated with genus in the the family Orbaceae in the class Gammaproteobacteria. Strain IPMB12T was most closely related to Gilliamella mensalis LMG 29880T with a 94.6 % 16S rRNA gene sequence similarity. Strain IPMB12T showed less than 71.6 % average nucleotide identity, less than 71.5 % average amino acid identity and less than 21.2 % digital DNA-DNA hybridization identity compared to the strains of related genera within the family Orbaceae. The major fatty acids of strain IPMB12T were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0 and C14 : 0. The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, one uncharacterized phosphoaminoglycolipid and one uncharacterized aminophospholipid. The major isoprenoid quinone was Q-8. Genomic DNA G+C content of strain IPMB12T was 39.3 mol%. On the basis of phenotypic and genotypic properties and phylogenetic inference, strain IPMB12T represents a novel species of a new genus in the family Orbaceae, for which the name Zophobihabitans entericus gen. nov., sp. nov. is proposed. The type strain is IPMB12T (=BCRC 80908T =LMG 32079T=KCTC 82347T=KACC 22323T).
