The 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 کاملDual-mode cultivation of Chlorella protothecoides applying inter-reactors gas transfer improves microalgae biodiesel production.
Chlorella protothecoides, a lipid-producing microalga, was grown heterotrophically and autotrophically in separate reactors, the off-gases exiting the former being used to aerate the latter. Autotrophic biomass productivity with the two-reactor association, 0.0249gL(-1)h(-1), was 2.2-fold the value obtained in a control autotrophic culture, aerated with ambient air. Fatty acid productivity was ...
متن کاملEnhanced Vitamin B12 Production using Chlorella vulgaris
Microalgae Chlorella Vulgaris is enriched in vitamin B12 and cobalt ion which is positioned in the center of the vitamin molecule. This study aimed to investigate how different concentrations of cobalt chloride salt affected the vitamin B12 production by utilizing CO2 gas, to assess C. vulgaris biomass. Therefore, Bold’s basal medium used as the medium and 0.5, 1....
متن کاملLipid 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 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...
