already knew the three main species of symbiotic bacteria did not make carotenoids. She also was pretty sure the aphids didn't get their carotenoids from their diet. Aphids eat by sucking the ...

Carotenoids are pigments in plants, algae, and photosynthetic bacteria. These pigments produce the bright yellow, red, and orange colors in plants, vegetables, and fruits. Carotenoids act as a ...

Some chloroflexi bacteria are also photosynthetic, but produce energy using different types of chlorophyll and different types of carotenoids, which manifest as slightly different colors.

Some microbes in the colon produce carotenoids, which have a prebiotic-like effect and can cause beneficial bacterial changes associated with improved health. The metabolism and absorption of ...

Bacteria grown on a solution of sorghum lignin secrete products like PDC into the surrounding media, which must be separated from the cells (right), which contain carotenoids, yielding two ...

Gold-colored strains of Staphylococcus aureus bacteria, which get their color from antioxidant compounds called carotenoids, tend to cause more disease than colorless strains. Carotenoids also ...

Aphids carry beneficial bacteria but none of their genomes carry any traces of the genes required for creating carotenoids. And aphids that are cured of their hitchhikers don’t lose their colour.

Among the deadliest of resistant bacteria is MRSA, which killed 19,000 Americans in 2005 alone. 14. MRSA’s deadliness comes in part from a class of chemicals known as carotenoids, which MRSA uses to ...
