3β‐Methylbacteriohopanepolyol derivatives were isolated from three bacteria, Acetobacter pasteurianus ssp. pasteurianus, Methylococcus capsulatus and Nostoc muscorum , and identified by spectroscopic methods and direct comparison with 3β‐methyldiplopterol and 3β‐methylhopan‐29‐ol synthesized from 22‐hydroxyhopan‐3‐one. The 3β‐methylhopanoid content of A. pasteurianus ssp. pasteurianus could be dramatically increased (up to 60% of the total hopanoid content) by addition of L ‐methionine, the actual methyl donor, to the culture medium.
