Studies concerning the Biosynthesis Capacity of Carotenoid Pigments in Rhodotorula Sp
نویسنده
چکیده
The quantity of extracellular carotenoid pigments in Rhodotorula sp., determined by the absorbance observed at 520 nm, reached a maximum after 4 days, varying between 0,8729 μg/g of dry mass in A2 and 7,5365 μg/g of dry mass in B1.The accumulation of carotenoid pigments in the intra-cellular environment had values between 1,888μg/g of dry mass in B2E and 1.711μg/g of dry

Carotenoid Production by Rhodotorula sp. on Fruit Waste Extract As a Sole Carbon Source and Optimization of Key Parameters
Fruit waste extract was selected as the sole substrate for carotenoid production and the effect of parameters like pH, temperature and agitation have been studied. A two-step simple sequential strategy was employed for the optimization of carotenoid production by Rhodotorula rubra. In the first step, one factor at a time was employed to evaluate the impact of pH on carotenoid production. Th...
متن کاملEvaluation of the Relationship between the Incubation Time and Carotenoid Production in Rhodotorula Slooffiae and R. Mucilaginosa Isolated from Leather Tanning Wastewater
Objective(s): Carotenoids which are naturally synthesized by fungi such as yeasts can act as an antioxidant which is closely related to their ability to decrease the risk of a variety of degenerative diseases. In recent years, the increase of demand for carotenoids obtained from natural sources has promoted major efforts to improve carotenoid production from biological sources such...

Carotenoids are one of the most important and widely distributed pigments in nature and have essential biological functions in organisms. They also impart distinctive and attractive coloration to the breeding animals. Over the past two decades, application of microbial carotenoids has attracted the attention of researchers due to their natural and economic advantages. However, carotenoid prod...

متن کاملImproving carotenoid pigments production in Rhodotorula mucilaginosa using UV irradiation
Rhodotorula yeasts were isolated from various local sources in Damascus, Syria, during 2012 and 2013. Fifty isolates (23 from leaves trees, 13 from different soils, 6 from different meats, 6 from dairy products, 1 pickle and 1 traditional sweet) were identified using API 20C AUX system. Isolated yeasts were classified into three Rhodotorula species: R. mucilaginosa, R. glutinis and R. minuta re...
