For this project, various extraction methods were used to extract pectin from Pastinaca Sativa and alginate from Macrocystis. These extractions were then dried and used in treating 250mL of manure along with a CaCl2 or FeCl3 coagulant. It was found that CaCl2 was not as effective as FeCl3 in coagulating manure. But the results obtained suggest that pectin and alginate obtained with a simpler extraction method is just as effective as the highly purified and refined pectin and alginate produced for the food industry, in the treatment of CAFO manure. The liquid portion of the manure treatments were tested for the dissolved nutrients of nitrate, ammonia, and phosphorus. Results suggest that, and the polysaccharides obtained by the simpler extraction method are as effective as highly purified polysaccharides. More testing needs to be done to determine effectiveness for binding ammonia. Next steps should include testing the length of time needed for sonication that would yield the highest levels of pectin and alginate. Another next step would be testing the amount of dissolved nutrients in the parsnip and seaweed before extraction.
