Comparative dataset on productivity, proximate, biochemical and pigment content of marine sp. and freshwater sp. microalgae.

The dataset includes a comparative analysis of sp. and sp. to characterize their productivity, proximate composition, biochemical composition and pigments. Growth data were collected through cell density and optical density and subsequently mass-cultured to utilize biomass for other analyses. The onset of the stationary phase (12 to 18 days) varied between the species. Volumetric productivity, areal productivity, and SGR were also significantly higher ( ˂ 0.05) in sp. whereas, sp. showed significantly higher ( ˂ 0.05) cell duplication time and cell doublings per day (K). sp. showed significantly higher ( ˂ 0.05) protein (42.86±1.13%), carbohydrate (13.56±0.48%) and lipid (27.4 ± 0.69%) content than sp. Significantly higher ( ˂ 0.05) polyunsaturated fatty acids (PUFA) were obtained from both sp. and sp. Non-essential amino acids were prevalent in both microalgae than essential amino acids. Significantly higher ( ˂ 0.05) chlorophyll-a (5.51±0.00), chlorophyll-b (2.27±0.04) and phycobiliprotein (2.32±0.05) were found in sp. Conversely, sp. exhibited higher ( ˂ 0.05) carotenoid content (2.48±0.05). These findings may contribute to the screening and utilization of these microalgae in the aquaculture, pharmaceuticals, and nutraceuticals sectors.
