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 کاملNew dual-stage pH control fed-batch cultivation strategy for the improvement of lipids and carotenoids production by the red yeast Rhodosporidium toruloides NCYC 921.
The optimal medium pH to produce biomass and fatty acids by the red yeast Rhodosporidium toruloides NCYC 921 is 4.0, and to produce carotenoids is 5.0. Based on this difference, a dual-stage pH control fed-batch cultivation strategy for the enhancement of lipids and carotenoids production by this yeast was studied. The results showed that when the yeast growth phase was conducted at pH 4.0, and...
متن کاملNew at-line flow cytometric protocols for determining carotenoid content and cell viability during Rhodosporidium toruloides NCYC 921 batch growth
Rhodosporidium toruloides NCYC 921 batch growth was monitored as a means to evaluate the yeast biomass potential as a source for the production of carotenoids and other lipids. Carotenoid content, cell viability and size were assessed by multiparameter flow cytometry. The saponifiable lipid fraction was assayed by gas–liquid chromatography. The carotenoid production increased during the station...
متن کاملSelecting low-cost carbon sources for carotenoid and lipid production by the pink yeast Rhodosporidium toruloides NCYC 921 using flow cytometry.
The present work studied low-cost carbon sources for carotenoid and lipid production using the yeast Rhodosporidum toruloides NCYC 921. Carob pulp syrup and sugarcane molasses at different concentrations were used as low-cost carbon sources in R. toruloides batch cultivations. Carob pulp syrup containing a total sugar concentration of 75 g L(-1) induced the highest total fatty acid productivity...
متن کاملConcomitant Production of Lipids and Carotenoids in Rhodosporidium toruloides under Osmotic Stress Using Response Surface Methodology
As a replacement to existing fossil fuels, biofuels, have proven their worth; however, their widespread use is limited due to inconsistent yields, higher costs and poor productivity. An oleaginous yeast, Rhodosporidium toruloides has been reported to accumulate substantial amounts of lipids (that can be converted to biofuels) and therefore, it was selected for study and optimization. Apart from...
