B. braunii was able to grow in all the tested concentrations of sodium chloride (17 mM to 85 mM). The biomass
yields increased with increasing concentration of sodium
chloride and maximum biomass was achieved in 17 mM
and 34 mM salinity (Fig. 1). The variation in pH from 8.5 to
9.5 observed during the experimental period was independent of sodium chloride concentration. It was evident from
the data (Fig. 1) that the decrease in phosphate was due to
its utilization by the alga, which was not inXuenced by
salinity concentration.
