Molecular Regulation of Carotenoid Accumulation Enhanced by Oxidative Stress in the Food Industrial Strain Blakeslea trispora

mycolabadmin

Researchers studied how stressful conditions can make a fungus called Blakeslea trispora produce more carotenoids, which are natural pigments used to color food products. When exposed to chemical stressors like rose bengal or hydrogen peroxide, the fungus produced significantly more carotenoids – up to four times more in some cases. The study identified specific genes and cellular pathways responsible for this increased production, which could help food companies produce natural food colorants more efficiently.

Adaptive laboratory evolution of Blakeslea trispora under acetoacetanilide stress leads to enhanced β-carotene biosynthesis

Scientists used a technique called adaptive laboratory evolution to make a fungus called Blakeslea trispora produce much more beta-carotene, a natural compound that converts to vitamin A in the body and has health benefits. By gradually exposing the fungus to increasing levels of a chemical stressor over 16 months, they helped it evolve to produce 45% more beta-carotene. The adapted fungus showed changes in its genes, physical structure, and fat composition that helped it thrive under stress while making more of this valuable compound.
