Optimization of growth conditions of isolated algae from Coastal areas of Andhra Pradesh

Algae are significant members of aquatic ecosystems, with roles in carbon sequestration, nutrient cycling, and other biotechnology applications. The current research involves the isolation, culture, and optimization of the growth of algae collected from three ecologically diverse locations in India—Chirala, Nellore, and Machilipatnam. Water samples were collected and cultured in the laboratory under controlled conditions in different culture media, nutrient compositions, temperatures, PH levels, light intensities, and aeration types. The results indicated significant differences in algal diversity and growth response to environmental factors. Coastal regions (Chirala and Machilipatnam) were found to be richer in species composition than the inland freshwater site (Nellore). The optimal growth was observed at 32°C, PH 7.5, and indirect sunlight, with some species-specific variations. Algal strains cultured in nutrient-rich media exhibited higher biomass accumulation, suggesting their application in biofuel generation and environmental remediation. The research provides significant insights into algal culture optimization for industrial and ecological applications, promoting sustainable biotechnology solutions.
