a)Could sulfate reducing bacteria (SRB) grow in the absence of sulfate? b)Since lactate is known to be a preferred substrate by some SRB, use thermodynamic principles. to explore whether the following reaction could occur in an anaerobic digester environment: CH3CHOHCOO- + H2O CH3COO- + CO2 + 2H2 If needed, you can assume lactate and acetate concentrations to be the same, and that the partial pressures of CO2 and CH4 are 0.4 atm and 0.6 atm, respectively
