in this study, we have investigated the effects of mix of tomato (solanum lycopersicum) & carrot) daucus carota ( and red bell pepper )capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (astronotus ocellatus sp., agassiz, 1831), which are generally white with red patches in the dorsal skin. the fish were fed diets con...

To better understand the evolution of red-green color vision in vertebrates, we inferred the amino acid sequences of the ancestral pigments of 11 selected visual pigments: the LWS pigments of cave fish (Astyanax fasciatus), frog (Xenopus laevis), chicken (Gallus gallus), chameleon (Anolis carolinensis), goat (Capra hircus), and human (Homo sapiens);and the MWS pigments of cave fish, gecko (Gekk...

BACKGROUND Traditional submerged fermentation mainly accumulates intracellular orange pigments with absorption maxima at 470 nm, whereas extractive fermentation of Monascus spp. with Triton X-100 can promote the export of intracellular pigments to extracellular broth, mainly obtaining extracellular yellow pigments with absorption maxima at approximately 410 nm. In this study, a strain of Monasc...

PURPOSE Salamander retinas are known to contain at least three cone pigments and two rod pigments. The purpose of this study was to clone and characterize the visual pigments from salamander cones. METHODS cDNA fragments of cone pigments were amplified from a salamander retina cDNA library by PCR using a pair of primers with consensus for visual pigments. These fragments were cloned and used ...

the anthocyanins of siahe sardasht variety (vitis vinifera l. var. s.s.) were extracted from freezed samples and were purified by adsorption on cation-exchange resin column. individual pigments were separated by tlc on cellulose plates. monomeric anthocyanin content that was determined by ph-differential, was 1740.11±3.58 mgl?1 (based on malvidin 3-glucose). five major pigments were identified ...

The demand for natural colors is increasing day by day due to harmful effects of some synthetic dyes. Bacterial and fungal pigments provide a readily available alternative source of naturally derived pigments. In contrast to other natural pigments, they have enormous advantages including rapid growth, easy processing, and independence of weather conditions. Apart from colorant, bacterial and fu...
