It is highly nutritious and serves as an excellent source of protein for feed and food supplementation. The present study was carried out to utilize molasses as an organic additive for Spirulina cultivation. Typically, Spirulina is grown in conventional Zarrouk’s medium, which requires high-quality NaHCO₃. To reduce the cost of the medium, Spirulina was cultivated using CFTRI medium supplemented with different concentrations of molasses (diluted and supernatant). The molasses, being rich in carbon, was expected to enhance Spirulina growth. Growth performance was evaluated using optical density (OD) and chlorophyll-a content. In this study, Spirulina showed good growth in both CFTRI medium and CFTRI medium supplemented with organic molasses.
