People's concerns about the use of synthetic additives have doubled the importance of the need for research in the field of production of natural pigments, especially microbial pigments. Therefore, in this study, the spore suspension of Monascus purpureus was treated using ultraviolet light at random times (20, 30, 45, 60 seconds) and intervals (20, 30, 35 cm). Then, six suspicious colonies were selected to study the morphological characteristics and their pigment production and biomass growth were studied as liquid culture. The results showed that ultraviolet light caused morphological changes in Monascus purpureus. Pigment production in treated samples increased significantly compared to wild strain (p
