Description: |
Oceanic stretches experiencing perpetual darkness and extreme limitation of utilizable organic matter often rely on chemosynthetic carbon (C)-fixation. C-fixation is not limited to carbon-deplete environments alone but might also occur in varying degrees in carbon-replete locales depending on the nature and concentration of utilizable carbon, electron donors and acceptors. The present experiment estimates the differential rates of C-fixation by archaea and bacteria along with the effects of different electron donors. [Source: Journal of Marine Systems]
