Light Requirement for the Carotenoids Production by Mucor hiemalis
Objective Fungi produce many different carotenoids and some are attractive in medical and industrial sources. In this work the ability of Mucor hiemalis (PTCC 5292) to produce carotenoids in media with different nitrogenous and carbon sources and incubation with white, yellow, blue and red lights (15W, 220V, E27) against dark-grown were studied. Materials and Method The microorganism cultiva...
متن کاملPlant carotenoids: pigments for photoprotection, visual attraction, and human health.
Plant carotenoids are red, orange, and yellow lipid-soluble pigments found embedded in the membranes of chloroplasts and chromoplasts. Their color is masked by chlorophyll in photosynthetic tissues, but in late stages of plant development these pigments contribute to the bright colors of many flowers and fruits and the carrot root. Carotenoids protect photosynthetic organisms against potentiall...
متن کاملCarotenoids in photosynthesis: absorption, transfer and dissipation of light energy
The functioning of carotenoids in photosynthesis is discussed in relation to the reaction mechanism. The energy transfer process from the allenic carotenoid, fucoxanthin, to chl a was intensively investigated in the newly isolated fucoxanthin-chl a / c protein assembly (FCPA) from a brown alga Dictyota dichotoma. The transfer time was shorter than 3 ps at 15°C. The energy level responsible for ...
متن کاملCarotenoids and their isomers: color pigments in fruits and vegetables.
Fruits and vegetables are colorful pigment-containing food sources. Owing to their nutritional benefits and phytochemicals, they are considered as 'functional food ingredients'. Carotenoids are some of the most vital colored phytochemicals, occurring as all-trans and cis-isomers, and accounting for the brilliant colors of a variety of fruits and vegetables. Carotenoids extensively studied in th...
