In A. vinelandii, the major compound was a novel bacteriohopanepentol ether accompanied by a similar bacteriohopanetetrol derivative: in both compounds, the hopanoids are linked via an ether bond to a carbapseudopentose moiety often found in bacterial hopanoids. In the two Beijerinckiaspecies, diplopterol and 2β-methyldiplopterol were accumulated in much larger amounts than those usually recorded in hopanoid-producing eubacteria, while 2β-methyldiploptene was isolated for the first time from B. mobilis.Whereas in B. mobilisaminobacteriohopanetriol was the only C35hopanoid, the simultaneous presence of bacteriohopanetetrol and aminobacteriohopanetriol in B. indicais a rather unusual feature., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-140-10-2749
