Dataset representing growth performance, nutritional assay and biochemical profile of Oscillatoria spp.

Cyanobacteria are regarded as vital constituents of aquatic ecosystems which recently become viable option for bioremediation since it can remove contaminants from polluted water. They possess intriguing metabolic properties and exhibit differential growth patterns. This study elucidates the isolation and identification of two marine and two freshwater indigenous Oscillatoria spp., their growth performance, nutritional composition along with intricate biochemical profiles. Agar streak plate method was used for the isolation, growth curve was determined through chlorophyll content and optical density. Freshwater and marine Oscillatoria spp. were mass cultured in commercial Bold Basal Media and Conway media respectively. Wet biomass was harvested through centrifugation at the early stationary phase of their respective growth curve and oven-dried at 40 °C to determine the nutritional and biochemical profiles. Oscillatoria sp. 2 displayed significantly higher (p ˂ 0.05) chlorophyll-a (22.72 ± 0.04 µg/mL) and OD value (1.87 ± 0.03) in the stationary phase (9th to 11th day) than the other species. Crude protein contents (%) varied from 21.56 ± 0.09 to 56.97 ± 0.03. Crude lipid (%) ranged from 9.07 ± 0.07 to 17.13 ± 0.13 and Crude fiber content (%) showed the range from 7.49 ± 0.15 to 17.04 ± 0.08. Fatty acid and amino acid were also found variable among the species. Present study will contribute to the meticulous selection and characterization of Oscillatoria sp. to utilize it in the rigorous scientific investigations and diverse commercial applications.
