Rhodotorula Strains Isolated from Seawater That Can Biotransform Raw Glycerol into Docosahexaenoic Acid (DHA) and Carotenoids for Animal Nutrition

Due to the overexploitation of industrial fisheries, as principal source fish oil, well increasing replacement synthetic pigments for animal nutrition, we need find sustainable sources these essential nutrient productions. Marine Rhodotorula strains NCYC4007 and NCYC1146 were used determine biosynthesis docosahexaenoic acid (DHA) carotenoids by biotransforming raw glycerol, a waste product biodiesel. To evaluate presence inhibitory substances in both also grown analytical grade glycerol glucose main carbon separately. With showed significant correlation between DHA production intracellular phosphorous concentrations. NCYC1146, new strain genetically described this work, can produce canthaxanthin but only when is source. Then, could synthesize phospholipid, depends on kind NCYC1146. Finally, malate dehydrogenase activity be proxy metabolisms marine Rhodotorula. This first evidence that are capable synthesizing using an alternative low-cost potentially scale their nutrition.
