Description
Manlin Yan and three colleagues work in 2026 with a yellow mutant of the green alga Chlorella that barely makes chlorophyll, a trait that could simplify production of the eye-health pigment lutein. Less green pigment means a purer lutein extract at the end of processing. The team grew the original strain and the mutant under three feeding modes and compared pigments and gene activity.
The mutant's chlorophyll a fell to about a ninth of the original strain's level, and its chlorophyll b nearly vanished. The original strain made lutein fastest when fed both light and carbon, while the mutant did best growing on sugar in the dark. Glucose suited the mutant better than acetic acid. Gene comparisons between the strains traced how the two pigment pathways are regulated together.
