Experimentation was also done on eight strains of filamentous fungi, which were known as producers of amylase and glucoamylase for digesting raw starch. Aspergillus oryzae strains showed high efficiency in the removal of COD and TOC, starch hydrolysis and production of fungal biomass in the medium of the synthetic cassava starch processing (SCSP) wastewater containing pure cassava starch. With A. oryzae KCC FOOI0, treatment efficiency obtained 72% (TOC), 81 % (COD), 94 % (starch) and 2.4 gil of biomass after 14-day incubation. The presence of cyanide caused inhibition for the growth of filamentous fungi. The toleration of A. oryzae IFO 30113 to cyanide was associated with its ability to remove cyanide. Ammonia was indicated as the end product of biodegradation of cyanide. Volatilization and microbial metabolism could be considered as...
