    EPA/ September EFFECT OF PHOSPHORUS REMOVAL PROCESSES ON ALGAL GROWTH By Jan Scherfig Peter S. Dixon Richard Appleman Carol A. Justice Project EJH Program Element 1B Project Officer Thomas E. Maloney Pacific Northwest Environmental Research Lab, Environmental Protection Agency Corvallis, Oregon Prepared for OFFICE OF . Lily Racey-Dennis Ap BIOL The Effect of Phosphorus and Carbon on Algal Growth Introduction Algal growth increases with the presence of the great quantities of nitrogen and phosphorus causing the undesirable consequences in the water. Many aquatic areas that are near sources of pollutions from agricultural farming, industrial plants, or even fertilizers, deposit a significant.

    Introduction Calcium Chloride and Calcium Nitrate used as variables. Calcium chloride: used in road salts Calcium nitrate: used in fertilizers Both major runoffs in the region Chlamydomonas and Euglena alga used as experimental subjects. Two types of algae are common algal models 3File Size: KB. Scientists debate the best way to tame toxic algal blooms. But when researchers enriched lakes with both phosphorus and nitrogen, the algal crop ballooned by a factor of The findings hint.

    We hypothesize that an increased nitrogen and phosphorus concentration in water will allow for a higher growth rate of algae and certain types of bacteria that feed on the algae. This will decrease the amount of oxygen available in the environment for other organisms as they : Christina Eyman, Kelli Case, Brya D'Abrosca, Jeremy Kaplan.

Algal growth aqueous factors other than nitrogen and phosphorus; selected biological references [by] Kenneth M. Mackenthun [and] William Marcus Ingram. The hypothesis is there will be greater algal growth in higher concentrations of nitrogen and phosphorus.

Figures 2 and 3 show an approximate increase in the concentrations of nitrogen and phosphorus levels over a period of two weeks. With the exception of cell 4, a decrease in phosphorus and nitrogen levels parallel an increase in algal File Size: 1MB.

Grobbelaar Unit for Limnology, University of the OFS, BloemfonteinSouth Africa (Received 23 February ; revised version received 5 March ; accepted 30 May ) ABSTRACT An adequate supply of nitrogen and phosphorus is Cited by:   Author of Algal growth aqueous factors other than nitrogen and phosphorus, Environmental regulations handbook, Basic concepts in environmental management, Nitrogen and phosphorus in water, Toward a cleaner aquatic environment, The practice of water pollution biology, Biological associated problems in freshwater environments, Limnological aspects of recreational lakes.

Only a few of these elements can be removed from water through treatment at this time. Althrough Goldman () and Skulberg () have implicated magnesium, iron and molybdenum, and other trace elements as limiting factors for algal growth in some waters, most attention has been directed towards nitrogen and phosphorus as limiting by: highest amounts of nitrogen and phosphorus and control growth of the sites.

Therefore, phosphorus is likely to be the limiting nutrient since it returned the greatest algal growth. The East branch site had the greatest increase of chlorophyll a levels on the phosphorus bioassays.

Phosphorus has long been recognized as the controlling factor in plant and algae growth in Wisconsin lakes and streams. In small doses, phosphorus (P) is a good thing. It’s necessary for organisms to grow, which is why farmers apply it to their crops and homeowners apply it to their gardens.

Algae and the Nitrogen Cycle The growth of all organisms depends on the availability of mineral nutrients, and none is more important than nitrogen, which is required in large amounts as an essential component of peptides, proteins, enzymes, chlorophylls, energy-transfer molecules (ATP, ADP), genetic materials (RNA, DNA), and other cellular constituents.

the poorest algal growth in undiluted wastewater was possibly due to a high NH 4 -N concentration of 1, mg L − 1, resulting in an adverse impact on the photosynthesis of S. obliquus. The effect of nutrient conditions on the period of growth phase of N. palea is shown in Appendix A Table S3.

The changed nitrogen and phosphorus concentrations impacted the growth phase of N. palea significantly. As the ambient phosphorus concentration increased from to to mg/L, the growth phase of N. palea lengthened from 13 to 15 to 16 days, respectively; for nitrogen Cited by: 6. Among the selected environmental variables, promotion of the interactive effects of nitrogen and phosphorus together with the optimum total nitrogen/phosphorus mass ratio (between and ) was determined to be the most significant stimulating parameter associated with algal blooming development dominated by non-nitrogen-fixing by: 9.

A HAB can occur in fresh, marine (salt), and brackish (a mixture of fresh and salt) water bodies around the world HABs have occurred in every region of the United States 50% of states report a HAB every year in a freshwater body, and all coastal states report HABs in marine waters HABs are caused by organisms called phytoplankton, some of which can produce toxins 7,8.

The increased availability of these nutrients can disrupt the aquatic biological equilibrium to favour the enhanced growth of aquatic plant File Size: KB. Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils.

Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
