Bacterial pigments are compounds produced by bacteria that can be used to color or stain other materials. They are used in numerous applications, including as industrial operations, medical diagnostics, and food coloring. These astonishing compounds are also used to create unique and attractive colors in fabrics, cosmetics, and other products. The most common type of bacterial pigment is carotenoid, which is responsible for the yellow-orange color. I'll discuss here, a personal favourite Micrococcus luteus a microorganism with the color yellow.
Micrococcus luteus grows beautiful yellow colonies in nutrient agar. Belonging to the family Micrococcaceae this fascinating bacterium is a gram-positive to gram variable, nonmotile, tetrad-arranging, pigmented, saprotrophic coccus bacterium with cells ranging from 0.5 to 3 µm in diameter. M. luteus, an obligate aerobe, is a common component of the natural cutaneous microbiota of mammals and can be found in soil, dust, water, and air.
In terms of hydrophobicity, carotenoids are a group of extremely hydrophobic molecules with little or no solubility in water which usually do not increase with increase in temperature. Shape of the carotenoid molecule depends on isomeric forms (trans and cis) and can thus change properties of carotenoid affecting solubility and absorbability.
Natural carotenoids are secondary metabolites that exhibit antioxidant, anti-inflammatory, and anti-cancer properties. These types of compounds are highly demanded by pharmaceutical, cosmetic, nutr...
In humans, the most relevant biological functions of carotenoids are linked to their antioxidant properties, which directly emerge from their molecular structure. Carotenoids have been used as preservatives in cosmetics and, combined with other antioxidants or algal bioactive substances, also in creams and lotions for sun protection. The main applications of carotenoids are currently as dietary supplements, fortified foods, food color, animal feed and pharmaceuticals and cosmetics.
Carotenoid has gained a reputation amongst researchers for its robust antioxidant capabilities. Carotenoids have gained in popularity not only as nutraceuticals and nutricosmetics, but also as biologically active compounds This review reasons the inevitability of carotenoid fo…
Carotenoids are beneficial for human health. Current study describes the importance, chemical composition and functioning of carotenoids. It is well known that carotenoids support pigments acting in light absorbance mechanisms
Carotenoids are tetraterpene pigments, which exhibit yellow, orange, red and purple colors. Carotenoids are the most widely distributed pigments in nature and are present in photosynthetic bacteria, some species of archaea and fungi, algae, plants, and animals.
