Abstract: Gene expression of microbes in anaerobic sediment from the Peru Margin at depths up to 159 metres below the sea floor is analysed: anaerobic metabolism of amino acids, carbohydrates and lipids are seen to be the dominant metabolic processes, and genes associated with cell division are found to be correlated with microbial cell concentration, suggesting that ongoing cell division contributes to biomass turnover.
