Abu-Ruwaida, I. Banat, I. Hamdan] Summary: A continuous culture technique was used to optimize the medium composition and growth conditions of a mixed bacterial culture utilizing methanol. The improved medium resulted in satisfactory growth, high-yield coefficients and gave a product containing reduced polysaccharide concentrations. Optimal growth and biomass yields occurred at pH 6.8 a temperature of 37° C and dissolved oxygen at >20% saturation. The maximum growth rate was 0.58 h−1 and maximum biomass yield 0.48 g g−1. The protein content of the product ranged between 81%-83%, and nucleic acid content between 10%-12%, increasing with growth rate. The amino acid profile of the mixed culture product met and, in some cases, exceeded the UN Food and Agricultural Organization standard, indicating a good source of feed protein.
