lycopene is a natural and dominant pigment in tomato which today itsextraction enhancement from tomato and tomato products is trying. in this study atfirst wed use pectinase at 25, 30, 35 and 40 ml/kg concentration at 0, 30, 60, 90,120 and 180 effecting time in 55 0c constant temperature incubation. then beforeextraction half of samples were washed with 94% ethanol at 60 0c for 5 second. ithas ...

Background and objective: Pigment production by microorganisms is important due to more rapid growth, higher efficiency, easier extraction, and antimicrobial effects compared to other methods. The aim of the present study is to isolate and identify antibiotic pigment-producing actinomycetes from the soil of the Persian Gulf and to evaluate the antibiotic activity of their pigments in the second...

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...

Microalgae can produce various natural products such as pigments, enzymes, unique fatty acids and vitamin that benefit humans. The objective of the study is to study the bioaccessibility of carotenoids (β-carotene and lycopene) and vitamin E (α- and β-tocopherol) of Nannochloropsis oculata and Chaetoceros calcitrans. Analyses were carried out for both the powdered forms of N. oculata and C. cal...

A novel color control strategy for 3D printing was proposed based on a single channel nozzle with raw material. The basic principle to regulate the pH of extruded line through electrolysis which would result in change pH-sensitive pigments mixed printed materials. Using pulped yam as feedstock and sensitive pigment extracted from purple sweet potato (PPP), process parameters were optimized usin...

Natural products produced by microorganisms are important starting compounds for drug discovery. Secondary metabolites, including antibiotics, have been isolated from different Streptomyces species. The production of these metabolites depends on the culture conditions. Therefore, the development of a new culture method can facilitate the discovery of new natural products. Here, we show that myc...
