Many microalgae species can grow in brackish water or seawater, thereby avoiding demand for fresh water (Araujo 2011). Salinity is one of the environmental factors determining accumulation of lipids in algal cells. In this study the growth of Chlorella sp. biomass affected by salinity was investigated (Fig. 5). Algae survived under investigated conditions, but the biomass growth
decreased with a salinity increase. Differences between biomass concentrations were not significant while the salinities used were 35 g l-1 and 40 g l-1 (Fig.5, curves 3, 4) compared to the concentrations obtained when salinity was 30 g l-1 (Fig 5, curves 2)
