Comments P.8 left column : "However, [investigators'] new estimate is higher than the 14 fgC/cell used for the most recent global estimate of microbial biomass (primary source). The estimate of Kallmeyer et al. (primary source) was based on cell volumes determined by fluorescence microscopy for sediment samples from the oligotrophic South Pacific Gyre...A mean value of 14fgC/cell, however, may indicate that cells that live under energy-deprived conditions have a lower cell-specific carbon content than cells that live in environments with higher amounts of available energy from organic matter." fg C=10^-15 grams carbon
