![عکس صفحه اول مقاله: Production of extracellular β-glucosidase by Monascus purpureus on different growth substrates Production of extracellular β-glucosidase by Monascus purpureus on different growth substrates](/preview/png/35997.png)
Various agro-industrial residues in combination with peptone, NH4Cl and/or soy bran were screened as substrates for extracellular β-glucosidase (BGL) production by Monascus purpureus NRRL1992 on submerged fermentations (SmF). Higher BGL production was achieved when the agro-industrial residues were combined with peptone, and the utilization of NH4Cl (inorganic nitrogen source) had not supported high enzyme production. The combination between grape waste and peptone was the best for enzyme production, and was selected as the growth substrate for further investigations. The evaluation of the effects of the medium components on enzyme production showed that the influence of peptone was more important than grape waste. The production of extracellular BGL by M. purpureus was inducible and controlled by carbon (glucose) catabolite repression.
