Phylum Actinobacteria, Class Actinobacteria, Subclass Actibacteridae, Order Actynomycetales, Suborder Corynebacterinae, Family
Corynebacteriaceae, Genus Corynebacterium, Corynebacterium terpenotabidum Takeuchi, Sakane, Nihira, Yamada and Imai 1999.
Description is based on a single isolate.
Gram-positive coryneform, irregular short rods, 0.5-0.7/0.6-1.5 µm; some cells are
arranged in a V formation. Non-motile. Non-spore-forming. Tuberculostearic acid is
present. Mycolic acids are produced.
Colonies are grayish-white and rough on PY-BHI agar (Peptone Yeast-Brain Heart
Infusion) at 28 ºC. Aerobic; no anaerobic growth. Thiamin and biotin were required for
growth. Grows in: 0% and 8% NaCl media, but not in 10% NaCl media.
Isolated from soil. It is capable of degrading squalene. Squalene is a naturally abundant linear triterpene (C30 ) and an important
biosynthetic precursor of steroids and triterpenes in many living organisms.

of degrading squalene. Int J Syst Bacteriol 49, 223-229.
Positive results for catalase, Tween 80 hydrolysis, urease & Voges-Proskauer test. Fructose, glucose, mannose, lactate and ethanol
are utilized as carbon sources.
Negative results for aesculin hydrolysis, arginine dihydrolase, cellulose hydrolysis, gelatin hydrolysis, lysine decarboxylase, methyl
red, nitrate reduction, ornithine decarboxylase, oxidase, starch hydrolysis, tyrosine hydrolysis, acid production from: fructose,
galactose, glucose & mannose.
