expression of a bacterial β-carotene hydroxylase in canthaxanthin producing mutant Mucor circinelloides strains
Xanthophylls, primarily hydroxyland keto-derivatives of β-carotene (such as zeaxanthin, β-cryptoxanthin, canthaxanthin, echinenone and astaxanthin) have powerful antioxidant activity. Due to several positive effects on human and animal health, industrial application of xanthophylls shows an increasing tendency. In our previous study, carotenoid biosynthesis of the β-carotene producing zygomycet...
متن کاملNew apocarotenoids and β-carotene cleavage in Blakeslea trispora.
Mixed cultures of strains of opposite sex ("mated" cultures) of Blakeslea trispora contain trisporic acids and other apocarotenoids, some of which mediate the sexual responses of this fungus and other Mucorales. In mated cultures of the wild-type strains F986 and F921 we identified eleven apocarotenoids: two C(18) trisporoids, three C(15) compounds with a monocyclofarnesane skeleton, a C(13) co...
متن کاملExtraction and purification of -carotene from filamentous fungus Mucor azygosporus
-carotene has been used for years as natural food colorants and in cosmetics and healthcare due to their antioxidant property. The production of -carotene by Mucor azygosporus was evaluated, utilizing deproteinized waste whey filtrate. Since pigments are intracellular, their extraction needed after cell cultivation. In this study, different strategies for extraction of -carotene from M. azyg...
متن کاملA new regulatory mechanism controlling carotenogenesis in the fungus Mucor circinelloides as a target to generate β-carotene over-producing strains by genetic engineering
BACKGROUND Carotenoids are natural pigments with antioxidant properties that have important functions in human physiology and must be supplied through the diet. They also have important industrial applications as food colourants, animal feed additives and nutraceuticals. Some of them, such as β-carotene, are produced on an industrial scale with the use of microorganisms, including fungi. The mu...
متن کاملProduction, Purification, and Characterization of Polygalacturonase from Mucor circinelloides ITCC 6025
Mucor circinelloides produced an extracellular polygalacturonase enzyme, the production of which was enhanced when various production parameters were optimized. Maximum polygalacturonase (PGase) activity was obtained in 48 h at 30°C and pH 4.0 with pectin methyl ester (1% w/v) as carbon source and a combination of casein hydrolysate (0.1% w/v) and yeast extract (0.1% w/v) as nitrogen source. Th...
