4.4.1.1. Methanotrophic potential of CAB
The present analysis showed that the CAB of Pleuromamma spp. andCalanus spp. were found to have a high proportion of methanol
dehydrogenase genes (mxaF and mxaI) (Figure S2). This may be due to the
presence of Proteobacteria that involves methane oxidation viz.
Beijerinckiaceae, Methylococcaceae Methylocystaceae and
Methylacidiphilaceae (Verrucomicrobia) (Supplementary File-S2)[60].
