Human dietary deficiency is one of the dismaying questions due to the consumption of modern readymade foods in today’s hectic life pattern. Broad spectrums of the population are enforcing them toward malnutrition or nutritional deficiency in developing or underdeveloped countries. Additional nutritious and balanced food sources must be made available to control this present scenario. However, conventional protein-rich resources would not compensate for the demand for protein-rich food crops with an increase in the raising population. In this context, algae could be the potent higher protein-rich food supplement through carbon allocation to algal biomass generation without hampering the food chain, and soil resources depletion. Realizing the wide-scale adoption, high protein-yielding algal isolates with lowered nucleic acid content and higher chlorophyll content need to be explored considering its toxicity on community health. To this end, the diverse topographical locations of the Kangsabati River have been considered for the isolation of a broad spectrum of algal regimes to examine the quantity of total protein, nucleic acid, and chlorophylls. The present study has depicted that algal isolate DK1 contains the highest protein and chlorophyll content in best on the 12th day indulging 36% protein and 13% chlorophyll where the total nucleic acid amount is very limiting at 0.52%. Moreover, a DK1 alga has shown limited pathogenicity through hemolysin assay toward its acceptance for community usage as a single-cell protein-rich food supplement and alterative nutraceutical.
