capability of rhodotorula slooffiae to produce carotenoid

Rhodotorula is characterized by the absence of ballistoconidia, fermentation ability, and starch-like compounds. Biology of the species is not well-identified; Therefore molecular identification is required. Sequence analysis of the D1/D2 region can be used for the identification of the majority of Basidiomycetous species. Carotenoids which are natural pigments can be synthesized by some genera of yeasts such as Rhodotorula. The increase of demand for carotenoids obtained from natural sources has promoted major efforts to recognize potential microbial sources. The aims of this study were to identify a strain isolated from leather wastewater and to investigate its carotenoid production ability. The effect of 2 different medium [Semi-synthetic medium [MMS] and Yeast Malt extract medium [YM]] on biomass and carotenoid production was studied. In this experimental study, Sequence analysis of the D1/D2 region in addition to morphological and biochemical characterization to identify the strain was carried out. To isolate the carotenoid pigment, cells were suspended in acetone and broken using a homogenizer, followed by centrifugation and supernatant was separated; Thus pigments were measured spectrophotometrically at 450 nm using the extinction coefficient E[1%][450]=2500. Identification processes represented strain SG006 as a Rhodotorula slooffiae. The sequence was deposited in the Gene Bank database with accession number JX997835. The results showed that SG006 are able to produce carotenoid and MMS medium promoted carotenoid production. We found that Rhodotorula slooffiae showed the ability to produce carotenoid. However, further work is needed to optimize of the amount of product and to characterize the carotenoids
