The family Segniliparaceae

Abstract

Segniliparaceae, a family within the order Actinomycetales and suborder Corynebacterineae, comprises the sole genus Segniliparus with two species. The two type strains have been isolated from human sputum and are described to be opportunistic pathogens. They are aerobic, mesophilic, and chemoorganotroph. The most distinctive characteristic is the presence of ultralong C60-C100 mycolic acids. These are non-oxygenated α-mycolates with high levels of cis unsaturation, a feature solely present on Segniliparus species Hong (PLoS One 7:e39017, 2012). The type strain of Segniliparus rotundus is CDC 1076 T (=ATCC BAA-972 T = CIP 108378 T = DSM 44985 T) and of Segniliparus rugosus CDC 945 T (=ATCC BAA-974 T = CIP 108380 T = DSM 45245 T). Of each species, further strains have been isolated, mainly from the human habitat.
