Effect of pH, temperature and salinity on growth and biochemical parameters of Spirogyra sp.

Abstract

Microalgae are considered as the most promising renewable feedstock for bio-fuel production and bio-refineries, due to their advantages of fast growth, efficient carbon dioxide fixation, not competing for arable lands and potable water. Spirogyra sp. shows potential for the successful bio-fuel production. In the present study, effect of pH, temperature and salinity on growth and biochemical traits like biomass, lipid, carbohydrate, chlorophyll and protein content of Spirogyra sp. were assessed. Most of the traits were found higher in control condition. When Spirogyra sp. is grown at pH 7 higher yield of biomass, lipid, chlorophyll, carbohydrate and protein were seen. When isolated Spirogyra sp. is grown at 25 o
