Xylanase and pectinase production by Streptomyces sp. QG-11-3 was stimulated by DL-norleucine, L-leucine, DL-isoleucine, L-lysine monohydrochloride and DL-β-phenylalanine by up to 3.72- and 2.78-fold, respectively, whereas the combination of DL-norleucine, L-leucine and DL-isoleucine synergistically stimulated the xylanase and pectinase production by up to 6.72- and 5.62-fold, respectively. Glycine, DL-norvaline, DL-methionine, and DL-aspartic acid showed no significant stimulatory effect on enzyme production.
