In the field of natural pigment production, Monascus sp. is a well known name. These pigments have their applicability as food colorants. In this study, two Monascus sp. namely Monascus purpureus procured from MTCC, Chandigarh, India and Monascus sanguineus isolated inhouse, were compared for pigment production in submerged fermentation. Glycerol was used as sole carbon source and malt extract ...

Melanin pigment from natural sources like microorganisms was an attractive choice for commercial scale production. In this study, marine bacterium capable of melanin production on marine broth/agar was isolated and identified as Pseudomonas sp. (closely related to guinea) on phenotypic characterization. Melanin production activity of the isolate was studied in liquid mediums such as pure marine...

The production of pigments by edible filamentous fungi is gaining attention as a result of the increased interest in natural sources with added functionality in the food, feed, cosmetic, pharmaceutical and textile industries. The filamentous fungus Neurospora intermedia, used for production of the Indonesian food “oncom”, is one potential source of pigments. The objective of the study was to ev...

The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked a...

Although, that the solar energy is important for life continuity, there is need to protect large buildings from these radiations in summer and if the buildings are permitted to take these radiations, the cost of cooling will be too much. One of the most effective methods used to solve this problem is to coat buildings with specific pigments that reflect the solar infrared radiation. This wo...

To identify the role of avitaminosis E in the production of histological lesions and the distribution of an acid-fast pigment in the young cotton rat, weanling animals were maintained on a vitamin E deficient diet for 41 to 179 days. Since the pigment, lipofuscin, cannot be degraded by any cell, including the macrophage, it accumulates linearly with age of the animal and the length of the avita...

The accumulation of N-retinylidene-N-retinylethanolamine (A2E, a toxic by-product of the visual pigment cycle) in the retinal pigment epithelium (RPE) is a major cause of visual impairment in the elderly. Photooxidation of A2E results in retinal pigment epithelium degeneration followed by that of associated photoreceptors. Present treatments rely on nutrient supplementation with antioxidants. 9...

This article considers the technical, technological, and archival aspects of study Old Believer carved works art (icons crosses) Lower Pechora, whose origin is associated with Velikopozhensky Monastery on Pizhma River (currently, Ust-Tsilma District Komi Republic). The reason for hypothesis about local ochre used painting icons, as there are rich deposits in vicinity village Skitskaya (on site ...

photooxidation as an important process, which significantly affects the service life of the polypropylene products, has been the subject of much theoretical and experimental study. pigments used often change the light stabilities of polypropylene. out-door applications of pigmented polypr-opylene are now increasingly developed in products such as artificial grass. the aim of this work is to exa...
