    2012-11-1 · The algal flocculation efficacy of polyacrylamide grafted starch can be well explored for commercial algal harvesting. The very low dosage (e.g. 0.8 ppm) of the flocculant required is an added advantage as it is not expected to interfere with the product quality of the harvested algal biomass. The harvested algal biomass can be used for industrial applications (e.g. biodiesel production) or for food security (e.g…
