Summary
Filamentous fungi offer a novel source for natural blue pigments. Bikaverin, a fungal metabolite, turns blue with heat treatment and shows potential for food and pharmaceutical applications.
Area of Science:
- Microbiology
- Natural Products Chemistry
- Biotechnology
Background:
- Limited natural blue pigments exist, driving research into microbial sources.
- Current microbial blue pigments include phycocyanin and indigoidine.
- Filamentous fungi are promising for diverse pigment production.
Purpose of the Study:
- To review natural blue pigment production.
- To focus on bikaverin, a fungal pigment from Fusarium species.
- To explore bikaverin's potential applications.
Main Methods:
- Review of existing literature on microbial blue pigments.
- Analysis of bikaverin's properties, including its color change mechanism.
- Assessment of bikaverin's biological activities.
Main Results:
- Bikaverin, a red metabolite, exhibits a blue color upon thermal treatment.
- The mechanism behind bikaverin's heat-induced color change is currently unknown.
- Bikaverin possesses antimicrobial and antiproliferative properties.
Conclusions:
- Bikaverin is a potential source of a novel natural blue pigment.
- Its unique color-changing ability and biological activities suggest applications in food, cosmetics, and pharmaceuticals.

Pigmentation
3.9K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Changes in Skin Color: Clinical Perspectives
3.1K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Bile
2.9K
Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.
