Fig 3. Relative composition (%) of ‘regular’ amino-BHPs.

Fig 3

Distributions of aminotriol, aminotetrol and aminopentol, including their C-3 methylated homologues, where present, are shown for (a) methanotroph cultures including literature data (circles) and data from new cultures of Methylomicrobium, Methylomarinum, and Methylomarinovum (diamonds; this study) and (b) sediments and microbial mats from methane-rich marine settings (HMMV = Håkon Mosby mud volcano; BSCC = Barents Sea carbonate crust; AMV = Amon mud volcano; NZ = New Zealand; GD Golfo Dulce; GoM = Gulf of Mexico; PM = Peru Margin). Methanotroph literature data from [36,42,46,52,83]. aLiterature data from [36,42,83] was based on GC-MS hopanol quantifications after periodic acid treatment. Therefore, it is not possible to distinguish between amino- and non-amino-BHPs with the same number of functional groups. This is especially significant for the Type II aerobic methanotrophic bacteria that are known to synthesise bacteriohopanetetrol. For this reason, the axes of plot (a) are shown as functionality of the BHP-side chain.
