Whilst investigating the intact biohopanoid (bacteriohopanepolyol, BHP) distribution in Holocene sediments from Ace Lake (Antarctica), we have identified the presence of ab- bacteriohopanetetrol in sediments aged up to 9400 years BP.

Previously, this structure has only been observed in species of the nitrogen fixing bacterium Frankia. Its presence here in the sedimentary environment has implications for the interpretation of hopanoid ββ/αβ ratios in the geological record.
