Monascus purpureus C322 was cultivated on well-established production media to yield prevailingly red or orange pigment-rich ethanolic extracts. Once these extracts had been diluted by an overall factor of 50, they were used as such to dye raw wool standard specimens differently premordanted using alum or stannic chloride. Independently of the mordant used, the specimens dyed with the red pigme...

A high percentage of the pigments produced by Talaromyces spp. remains inside the cell, which could lead to a high product concentration inhibition. To overcome this issue an extractive fermentation process, perstraction, was suggested, which involves the extraction of the intracellular products out of the cell by using a two-phase system during the fermentation. The present work studied the ef...

BACKGROUND Monascus mycelia and pigments are promising sources of food and medicine with their potential pharmaceutical values and health-improving functions. Using high cell density fermentation of Monascus spp. to achieve higher mycelium and yellow pigment production is worthy to be researched. In this study, the characteristics and productivity shifting of pigments in high cell density cultu...

neuromelanin (nm) pigment accumulates with age in catecholaminergic neurons in man, and the ventral substantia nigra dopaminergic neurons that are the most vulnerable to degeneration in parkinson's disease (pd) contain the greatest amount of this pigment. in vitro data indicate that nm pigment is formed from the excess cytosolic catecholamine that is not accumulated into synaptic vesicles via t...

Aims: The study’s objective is to isolate, characterize pigment-producing bacteria from marine soil and optimize culture parameters such as pH, temperature, carbon, nitrogen sources enhance the pigment production. obtained was used dye cotton fabrics woollen thread.
 Place Duration of Study: samples were collected Marina beach, Chennai, Tamil Nadu study carried out at Department Animal Bio...

Various factors affecting the yields of luteoskyrin, a hepatotoxic mycotoxin, and related pigments in the liquid medium were studied. Maximal yields of luteoskyrin (0.13% by isolation) and of other pigments were attained in the late phase of the cultivation. The yield of the pigment was increased by supplying malt extract, malonic acid, glutamic acid, or asparagine. A useful material for prepar...

Conformational changes in the extradiscal regions of rhodopsin induced by illumination were investigated by modifying the visual pigment by mild treatment with cyanogen bromide prior to and after light exposure. Light induced an increased yield of cleavage of the Met bond 253-254 and a new cleavage at the Met bond 155-156 of the rhodopsin polypeptide chain. These residues, located at the beginn...

The linoleic acid hydroperoxide obtained by enzymatic peroxidation of linoleic acid was found to react with thiobarbituric acid to yield a red pigment. The optimum pH for the reaction was found to be 4.0. In the early stages of peroxidation of linoleic acid, thiobarbituric acid value, the amount of conjugated diene, oxygen consumption, and peroxide value were in parallel with one another. The d...

A method for isolating nuclei from Xenopus laevis embryos has been developed. This procedure enables the isolation of nuclei, free from contamination with yolk and pigment granules, at all stages of embryoic development. Using this method the nuclear yield is 60--70% of the estimated number of cells in the embryo. The DNA, RNA, histone and non-histone protein content of these nuclei during embr...

the research mainly intends to evaluate performance of strontium aluminum polyphosphate as an eco friendly zinc free anticorrosion pigment in formulation of the protective primer based on epoxy resin. comparing to zinc phosphate, the most effective content of the modified pigment was determined through electrochemical impedance spectroscopy. according to pull-off, the superior sapp incorporated...
