| Abstract | ||
| The present communication deals with light quality of different colours (Blue, Green, Red and White) on the growth and synthesis of photosynthetic pigments along with other value added products by the diazotropic blue-green alga Cylindrospermum muscicola MTC-30602. C. muscicola batch cultured for 10 days under controlled culture conditions. All four colours of light were observed to have an impact on the yields of dry biomass, chlorophyll, total carotenoids, phycobilin (c-phycocyanin, c-allophycocyanin, and c-phycoerythrin), total carbohydrate, total protein, and total fat. The results obtained indicated that increased production of biomass (dry weight), chlorophyll-a, total carotenoids, total protein was obtained when illuminated with white light. However, maximum synthesis of total carbohydrate, c-phycocyanin and c-phycoerythrin were observed under the influence of green light while c-allophycocyanin and lipid under the influence of red light. The findings suggested that exposure to various light colours may be in charge of the synthesis of additional naturally occurring compounds with added value, such as photosynthetic pigments. | ||
