Lipid production by Rhodosporidium toruloides Y2 in bioethanol wastewater and evaluation of biomass energetic yield.
The oleaginous yeast Rhodosporidium toruloides Y2 was employed to remove waste nutrients from bioethanol wastewater while simultaneously producing biomass enriched in microbial lipids. Under optimal conditions, the COD degradation ratio, biomass and lipid content reached 72.3%, 3.8 g/l and 34.9%, respectively. For accelerating biomass and lipid accumulation, different feeding strategies of subs...
متن کاملThe Production, Regulation and Extraction of Carotenoids from Rhodosporidium toruloides
Carotenoids are valuable pigments of commercial interest for various health benefits. There is rising demand for natural carotenoids from microorganisms, although the majority of industrially produced carotenoids are currently chemically synthesized. Rhodosporidium toruloides is oleaginous red yeast, which can produce large amounts of carotenoids and lipids simultaneously. It is also able to as...
متن کاملPurification and characterization of a cephalosporin esterase from Rhodosporidium toruloides.
A novel cephalosporin esterase (EC 3.1.1.41) from Rhodosporidium toruloides was purified to gel electrophoretic homogeneity. The enzyme is a glycoprotein with a molecular mass of 80 kDa. Upon deglycosylation, several forms of the enzyme were observed with a molecular mass range between 60 and 66 kDa. The isoelectric point of the enzyme is approximately 5.6, with the pH optimum for activity occu...
متن کاملHigh-density cultivation of oleaginous yeast Rhodosporidium toruloides Y4 in fed-batch culture
Microbial lipid production by the oleaginous yeast Rhorosporidium toruloides Y4 was studied using glucose as carbon source, in order to realize igh-density cell culture. Batch cultures demonstrated that there was little inhibitory effect with a substrate concentration of up to 150 g l−1. Flask ed-batch cultures were run for 25 days and reached a dry biomass and cellular lipid content of 151.5 g...
متن کاملOptimization of culture media for lipid production by Nannochloropsis oculata for Biodiesel production
Background: This study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of Nannochloropsis oculata. Methods: Culture of microalgae was done separately in Walne, F/2, Sato, and TMRL media. In the logarithmic and stationary growth phases, biomass production and lipid accumulat...
