| Abstract | ||||
| The aim of the present research was to investigate the feasibility of potato chips manufacturing wastes as a cheap substrate for the production of pigments by Monascus purpureus through solid-state fermentation. Maximum red, orange and yellow pigments of 126.5, 204.7 and 322.9 AU/g dry fermented material, respectively was achieved on potato wastes having 67% initial moisture content, 6.5 pH, 1.5mm particle size and supplemented with 2% ammonium sulphate. The optimum fermentation conditions were inoculation rate 140×103 spores /10g dry substrate, incubation period 15 days and fermentation temperature 30 in complete darkness. To the best of our knowledge, this is the first report on pigments production from M.purpureus using potato wastes in solid-state fermentation. | ||||
