Bioremediation of dye removal using algae: A hydroponics approach

An increase in industrialization is taking place and the need for dyes in the food, pharmaceutical, cosmetic, paper, textile, and leather industries continues to rise quickly. The risks of these dyes present in the environment has increased risk to human health. Excessive energy and financial expenses, excessive sludge formation, and chemical handling have all hampered the use of physicochemical treatments. In comparison, the bioremediation technology is a cost-effective, removal-efficient, and environmentally responsible way to address the issue. The impact of dye concentration on Chlorella vulgaris (SSAU 8) and Desertifilum salkilinema (SSAU 7) mixed culture was investigated in this study. These days, indicators including chlorophyll, carotenoids, antioxidant activity, carbohydrates, proteins, phycocyanin, and photosynthetic activity are used to evaluate the dye tolerance of this mixed culture. The results showed that the SSAU 7 and SSAU 8 mixed culture can effectively withstand dye concentrations of upto 20 ppm. Mixed culture with dye treated Oryza sativa is grown hydroponically; one is treated simply with dye, and the other is not. With increased stem length, root length, and germination percentage, these treatments clearly had a good impact on plant growth. These results highlight how mixed culture might improve crop development while reducing the negative ecological effects of dye.
