Single cell protein production was studied in a mixed bacterial culture grown in methane using batch and continuous culture techniques. Overall productivity was found to be higher in the continuous culture which gave a maximum productivity value p = 0.15 g/l/h. Methane and oxygen were consumed in the relation 1 : 1.7. Yield coefficients for methane, oxygen, and ammonium chloride were Y CH 4= 0.90, Y O 2= 0.26, and Y NH 4 Cl= 0.14. The crude protein content of the biomass was 71%.
