Isolation and characterization of a novel methylhopanoid from a facultative methylotrophic Corynebacterium sp.
Several compounds such as a methylhopanoid and carotenoids have been isolated and characterized from a facultative methylotrophicCorynebacterium sp., a vitamin B(12) producer. A novel pentacyclic triterpene, 2-methyl-22-hydroxyhopane has been identified by IR,(1)H-and(13)C-NMK and mass spectrometry. During the purification procedure a red pigment has been characterized as a mixture of several carotenoids by TLC and UV-VIS spectroscopy.
