Project description:We investigated a novel, simple approach to induce the production of cryptic secondary metabolites in actinomycetes by stimulating the organism with high-intensity monochromatic green light (180 radiation unit). Streptomyces coelicolor A3(2) produces blue antibiotic actinorhodin (ACT) and red antibiotic undecylprodigiosin (RED). Using these two pigment antibiotics as indicators, we found that sporulation acceleration and regulation of the antibiotic production pathways can be induced by using high-intensity monochromatic green LEDs. Therefore, we investigated the immediate response of S. coelicolor A3(2) gene expression to the strong green LED stimulation.
