Wohlfahrtiimonas larvae sp. nov., isolated from the larval gut of Hermetia illucens (Diptera: Stratiomyidae)

A novel, Gram-negative, facultative anaerobic, motile and short rod-shaped bacterium, strain KBL006T was isolated from the larval gut of Hermetia illucens, Black soldier fly. The 16S rRNA gene sequence of strain KBL006T showed 96.4 % similarity to that of Wohlfahrtiimonas chitiniclastica S5T. Strain KBL006T grew optimally at 30 °C, at pH 8.0 and in the presence of 1–2 % (w/v) NaCl. Oxidase activity and catalase activity were positive. The major fatty acids were C18:1 ω7c, C14:0, and C16:0. The major respiratory quinone was ubiquinone-8 (Q-8). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol, and two phospholipids. The G+C content of the genomic DNA was 45.2 mol%. Based on these polyphasic data, strain KBL006T is considered to represent a novel species in the genus Wohlfahrtiimonas, for which the name Wohlfahrtiimonas larvae sp. nov. is proposed. The type strain is KBL006T (= KACC 16839T = JCM 18424T).
