Production and biological activities of yellow pigments from Monascus fungi

World Journal of Microbiology and Biotechnology, 2016
Monascus yellow pigments (MYPs), are azaphilone compounds and one of the three main components of total Monascus pigments (MPs). Thirty-five hydrophilic or hydrophobic MYPs have been identified, with the majority being hydrophobic. Apart from screening special Monascus strains, some advanced approaches, such as extractive and high-cell-density ...

Biological activities of oligoketide pigments of Monascus purpureus

Food Additives & Contaminants, 1999
Rubropunctatin (1), monascorubrin (2), monascin (3) and ankaflavin (4) were purified from the mycelium of Monascus purpureus by flash chromatography on silica gel or reversed phase. Their embryotoxicity towards chicken embryos decreased in the order 2 > 1 > 3 > 4.

Beeturia and the biological fate of beetroot pigments

Pharmacogenetics, 1993
Beeturia, the passage of pink or red urine after the ingestion of beetroot, is said to occur in 10-14% of the population, and is more common in iron deficiency and malabsorption. A specific HPLC assay for betacyanins, the red beetroot pigments, in biological fluids was developed to study the prevalence of this apparent polymorphism in humans, and to ...

Perylene pigment wastewater treatment by fenton-enhanced biological process

Environmental Research, 2020
Polycyclic aromatic hydrocarbons (PAHs) are regarded as priority pollutants owing to their toxic, mutagenic and carcinogenic characteristics. Perylene is a kind of 5-ring PAH with biological toxicity, and classified as a class III carcinogen by the World Health Organization (WHO). Nowadays, some of its derivatives are often used as industrial pigments.

Sources, stability, encapsulation and application of natural pigments in foods

Food reviews international (Print), 2020
In recent years, the replacement of synthetic colorants with natural ones has attracted increasing consumers’ and market interest. Natural colorants include different groups of pigments, many of which possess also pronounced biological potential.

Pigments from Antarctic bacteria and their biotechnological applications

Critical Reviews in Biotechnology, 2021
Pigments from microorganisms have triggered great interest in the market, mostly by their “natural” appeal, their favorable production conditions, in addition to the potential new chemical structures or naturally overproducing strains.

Phototrophic pigment production with microalgae: biological constraints and opportunities

Journal of Phycology, 2014
There is increasing interest in naturally produced colorants, and microalgae represent a bio‐technologically interesting source due to their wide range of colored pigments, including chlorophylls (green), carotenoids (red, orange and yellow), and phycobiliproteins (red and blue).

Biological image segmentation based on object pigmentation

Proceedings of the 1991 IEEE Seventeenth Annual Northeast Bioengineering Conference, 2002
A methodology for segmenting biological images based on object pigmentation is proposed. The object of interest is extracted based on MacAdam's just noticeable difference (see J. Opti. Soc. Am., vol.32, p.247-74, 1942). The method combines pictorial and spectral information, into a single valued total color difference.
