Frondihabitans cladoniiphilus sp. nov., an actinobacterium of the family Microbacteriaceae isolated from lichen, and emended description of the genus Frondihabitans

A novel actinobacterium, designated strain CafT13T, was isolated from the thallus of the reindeer lichen Cladonia arbuscula sampled in the Austrian Alps (Koralpe). The organism was aerobic, with rod- to irregular-shaped cells (often forming dense clusters of cells when grown in liquid medium), Gram-stain-positive, oxidase-negative, catalase-positive and non-motile. It was able to grow at 1 °C and at low to neutral pH, but not above 30 °C or at high pH. The peptidoglycan type was B2β with ornithine as the diagnostic diamino acid. The menaquinones were MK-7 and MK-8. The polar lipid profile comprised diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, three unidentified glycolipids and one unidentified aminolipid. The predominant fatty acids were C18 : 1, C14 : 0 2-OH, C17 : 1ω9c, C16 : 0 and anteiso-C15 : 0. The mean DNA G+C content of strain CafT13T was 69.0±0.17 mol%. 16S …
