Abstract
The fungal pigments are a good alternative to currently used synthetic colourants and / or
natural colourants derived from plant materials. The aim of the present study was to investigate
the feasibility of cassava processing waste as a substrate for production of pigments by
Penicillium Purpurogenum in solid state fermentation (SSF). A pigment yield of 40.13 Colour
Value Units (CVU) / g of dry fermented substrate was achieved by using cassava processing
waste with optimized process parameters such as 50 % initial moisture content, inoculation
with 4.0 ml of spores (25×10 5 spores) / gram of dry substrate and an incubation period of 15
days with 1 % peptone at 30°C,. Thus, utilization of cassava processing waste for red pigment
production in this study could provide the most effective use of natural resources and lead
to technology development for further cost reduction
