摘要:
The present invention relates to novel hydroxylases, nucleic acid sequences coding therefore, expression constructs and vectors comprising these sequences, microorganisms transformed therewith, processes for the microbiological hydroxylation of isoprenoids, for example processes for converting beta-carotene into beta-cryptoxanthin and zeaxanthin, or canthaxanthin into astaxanthin.
摘要:
The present invention relates to the field of fungal biotechnology, more particularly to genetic engineering methods for the production of carotenoids in fungal hosts selected from Rhodospordium and Rhodotorula genera.
摘要:
The present invention relates to arecombinant Deinococcus bacterium exhibiting enhanced 2-C-methyl-D-erythritol 4-phosphate/1-deoxy-D-xylulose 5-phosphate (MEP/DXP) pathway, and its use for producing terpene or terpenoid compounds.
摘要:
The invention relates to a process for the enrichment, with carotenoids and proteins, of a biomass of a microalga cultivated under heterotrophic conditions, wherein said microalga is of the Chlorella genus, which comprises culturing said microalga in a minimum medium supplemented with a nitrogen source in organic form, preferably chosen from the group consisting of yeast extract, corn steep liquor, and a combination thereof.
摘要:
The present invention is directed to methods of producing algal biomass and algal cell cultures, and lipid compounds and compositions thereof, including fatty acids, carotenoids and fat soluble vitamins. The present invention is further directed to methods of preparing related food products and industrial and pharmaceutical compositions. In various exemplary embodiments, the methods comprise growing algae in a juice based medium, including a medium that contains natural nitrogen or a medium that is free of chemical additives and preservatives, to produce algal cell cultures, algal biomass, algae derived lipid compounds and compositions, and related products, all that can be certified organic.
摘要:
Methods of obtaining a carotenoid-containing composition were developed, in which degradation of carotenoids is suppressed even though extraction and purification are performed on a culture of microorganism that produces carotenoids including astaxanthin by simple steps using a lower alcohol which is a conventionally known solvent, and the compositions have high astaxanthin content and contain highly pure carotenoids and also have satisfactory crystal properties. Further addition of a simple step that promotes isomerization of astaxanthin successfully improved the carotenoid yield.
