Crude glycerol (CG) from biodiesel production is often contaminated with several compounds, including saponified fatty acids (SFAs). Photofermentative growth of Rhodopseudomonas palustris on glycerol leads to hydrogen production; however, R. palustris is inhibited by SFAs. This study examines inhibition of R. palustris by SFAs, finding that, with increasing concentration of SFA, growth rate falls, reaching zero at an SFA concentration of 0.2 mM. Methods for purifying CG were examined, namely (i… CONTINUE READING
