As a result of periodic acid oxidation followed by sodium borohydride reduction, the bacteriohopanepolyols, of unknown structure, from the methylotrophic bacteria Methylococcus capsulatus and 3 Methylomonas species, release a C 30 hopanoid, (22 S )‐hopan‐29‐ol, as major product, and traces of the C 29 hopanoid adiantol. Large amounts of hopanoids with an ethyl side chain are commonly found in almost all types of sediments. It is therefore probable that these are chemical fossils of the hopanoids from ubiquitous methylotrophic bacteria.
