Overexpression of the primary sigma factor gene sigA improved carotenoid production by Corynebacterium glutamicum: Application to production of β-carotene and the non-native linear C50 carotenoid bisanhydrobacterioruberin
Corynebacterium glutamicum shows yellow pigmentation due to biosynthesis of the C50 carotenoid decaprenoxanthin and its glycosides. This bacterium has been engineered for production of various non-native cyclic C40 and C50 carotenoids such as β-carotene, astaxanthin or sarcinaxanthin. In this study, the effect of modulating gene expression more broadly by overexpression of sigma factor genes on...
متن کاملThe isolation and description of two marine micro-organisms with special reference to their pigment production.
Two corynefonn organisms (A 1082 and A 1062) isolated from the skin mucus of Arctic cod, are described in detail. Strain A1032 may be a new species; strain A 1062 is a strain of Corynebacterium erythrogenes. Three carotenoid pigments, all with very similar absorption spectra, were found in both strains. Two of these pigments were identified as neoxanthin and sarcinaxanthin. "he third pigment ha...
متن کاملSelected examples of structure determination of natural carotenoids.
Selected examples of novel types of carotenoids studied in the author's laboratory during the past three years are discussed; including structural elucidation, total synthesis and biosynthetic considerations. Carotenoids of photosynthetic bacteria, particularly the aryl ketone okenone and cross-conjugated carotenals of the rhodopinal series, C50carotenoids of non-photosynthetic bacteria like de...
متن کاملCarotenoids: more than just beta-carotene.
Fruits and vegetables of the human diet contain many of the over 600 carotenoid pigments that have been identified in plants. Led by work with beta-carotene, researchers have constantly been learning more about the metabolism of these compounds in the human body. Research work is now expanding beyond beta-carotene in an effort to understand what happens to all the pigments found in the human di...
متن کاملCarotenoids in ornamental fish farming
The aquaculture industry has grown dramatically in recent years, with a multimillion-dollar market. There are a variety of freshwater fish, marine fish, mollusks, and ornamental fish cultivated in this industry. The pigment and coloring of ornamental fish are important characteristics for marketing. In edible fish, carotenoids are responsible for the pigmentation of body tissue, while in ...
