Table 1 Growth properties of the M82 culture incubated at different sulfate concentrations

From: Coexistence and competition of sulfate-reducing and methanogenic populations in an anaerobic hexadecane-degrading culture

Initial sulfate concentration (mM) Hexadecane consumption (mmol) Sulfate consumption (mmol)a Methane production (mmol)b Recovery of hexadecane carbon (%) Maximum specific methane production rate (month−1) (Sulfate reduction + methane production)/hexadecane consumed
