WebThe harvesting efficiency is very low at ~11% in the pH range of 6.5–8.5, while it dramatically increases to 83% and 94% with increase in pH to 10.5 and 12.5, respectively [ 37 ]. Similarly, a high harvesting efficiency of 94% was reported for Chlorococcum sp. R-AP13 at pH 12 [ 36 ]. WebBut when the pH of the wastewater was maintained at 7.5 using the phosphate buffer, the growth of E. coli was not affected even in the pres ence of algae, though the algal growth in both the flasks was about the same.
