Abstract

STARCH is a plant polysaccharide with unique applications in Iran. Its increasing production and processing recently have led to large volumes of industrial effluent as an environmental pollutant. In this study, an AMYLASE producing YEAST is isolated and identified as "Cryptococcus aerius" to investigate some of its characteristics such as its AMYLASE secretion and STARCH digesting patterns, kinetics of AMYLASE complex, and its capability for carotenoid production in dual culture. The results indicate that C.aerius is capable of soluble and raw maize STARCH digestion and assimilation. Raw STARCH digestion is scarce among YEAST species; hence, it is industrially important. C.aerius digests soluble STARCH in the first 10 hours of cultivation and on the basis of AMYLASE secreting patterns, it is therefore categorized with fast growing species on STARCH as carbon source. Non-pathogenicity, digestion of raw STARCH, heat stability of the secreted AMYLASEs complex (>55°C), and the optimum pH level of 5.5- 6 for AMYLASEs complex are the set of properties that make this species capable of use in microbial production on an industrial scale. Absorption of carotenoid extract obtained from DUAL FERMENTATION of C.aerius and Rhodotorula sp. indicates that the quality of CAROTENOIDS produced in DUAL FERMENTATION is the same as that produced from pure Rhodotorula sp culture.
