Different superscript letters in the same row indicate significant difference between averages (P < 0.05) by Tukey’s test; SEM = Standard error of the mean. Control = basal diet; Pichia Effluent = basal diet + P. pastoris X-33 grown in parboiled rice effluent supplemented with biodiesel glycerol; Pichia YPD = basal diet + P. pastoris X-33 grown in YPD medium.
