Abstract

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 M. purpureus. Pigment production in treated samples increased significantly compared to wild strain (p <0. 05). UV6 treatment in red, orange and yellow Pigment production showed a 5, 7, and 2. 8 times increase compared to wild strain significantly, respectively (p<0. 05). Pigment production during the first and second generations in UV3, UV4, UV6, UV7, and UV8 treatments did not show a statistically significant difference with each other: in other words, the treatments were stable significantly (p<0. 05). According to the results, Ultraviolet Light was an effective physical treatment to increase the production of red, orange, and yellow Pigments from the fungus M. purpureus and generally causes lasting changes in the strain.
