The objectives of the study were the isolation of Algae determination of physical, chemical and biological characteristics of the samples at intervals of 7 days, 14 days, and 21 days determination of Minimum Inhibitory Concentration (MIC) for fungi strain. The tannery effluent from the leather industry generates indiscriminate removal of organic and inorganic substances along with the discharge of suspended or gas-solids oil and grease, nitrogen-containing compounds, and heavy metals either alone or in their reduced salt form. Spirogyra SPFS2-g isolated from tannery effluent-enriched soil exhibited detoxification of tannery wastewater. The treatment of tannery wastewater with Spirogyra resulted in the reduction of COD, Cr(VI), total suspended solids (TSS), turbidity, Na+, Cl–, and NO3– in the order of 71.80, 100, 36.47, 22.77, 11.69, 27.87 and 62.33%, respectively after 21days of duration. As the bioremediation activity is highly regulated by cell metabolism, which in turn is controlled by media components such as carbon and nitrogen sources and their ratio in addition to other process parameters like pH, incubation temperature and aeration. Thus, in a future, there is a need to conduct process parameter optimization studies to improve the bioremediation efficiency of the isolate. It was recommended that Tannery effluents should be treated with biological methods before discharging to the environment or water bodies because, high salinity can primarily decrease the rate of enzymatic activity of non-halophilic and non-halotolerant organisms, thereby affecting the ecosystem, since salinity can cause dehydration to potential microbes that are not halophilic and halotolerant, wither crops leaves and also affect human health. The industries should employ the use of halophilic microbes in the biological remediation of salinity rather than the use of chemicals which are carcinogenic in nature and can cause other health effects on humans....
