    Thus, assuming optimal growth conditions, and maximum phosphate utilization, the maximum algal crop that could be grown from 1 kg of P would be 1 tonne of wet algae under laboratory conditions or kg in the field. If a cellular content of P in algae is % then 1 kg of P could be distributed among 1 kg of algae (wet weight).   Phosphates are consumed by algae, and held within its cell walls. When algae is present in water, phosphate levels seem lower, because so much of them are already consumed. That being said, when algae is killed by chlorine (or an EPA-Registered algaecide), the phosphates and other micronutrients are released back into the water.

Changes in cell architecture at the electron microscope level have been followed in um during conditions of phosphate starvation and rapid uptake. Cells from day-old cultures were starved of phosphorus for 5 days and then inoculated into a medium containing 10 mg PO 4 /liter. Polyphosphate bodies developed in five different areas of the cells: (1) in ribosomal areas, (2) on strands.

    The wide utilization of algae for food product manufacturing opens alternative ways for food acquisition, protecting both the food supply and the planet’s resources. The sustainability aspects of mass algae production implementation seem to be indisputable regarding . utilization of sewage in the production of algae that would be suitable for animal feeds, fertilizers, and other products (2). Algae may serve in the near future as commercial sources for vitamins. hormones, and antibiotics (3). It has been estimated that, each year, about 5 million tons of algal nutrients.

The effects of various external phosphate concentrations on physiological and cytological aspects of Plectonema boryanum have been studied. boryanum was found to tolerate a wide range of phosphate concentrations, from 1 to mg of phosphate per liter.

Reflecting the proceedings of a International Symposium on the Biochemistry of the Algae and Cyanobacteria, this book covers such topics as algal metabolism, bioenergetics, metabolic control, extracellular products, and aspects of biotechnology. The distinguished contributors review studies with marine macroalgae, as well as microalgae and prokaryotic cyanobacteria (blue-green algae).

Initiated by Indo-German cooperation on large-scale cultivation of microalgae, aspects of production, processing and utilization of the blue-green alga (cyanobacterium) Spirulina platensis were studied with regard to Indian conditions, with the immediate objective of utilizing the algal biomass at rural levels as animal feed.

Thus, simple techniques involving less energy and capital were. - you can’t have one without the other. Phosphates in your pool water are bad news because ortho-phosphate is the major algae food in pools.

Algae can get by, and even proliferate, on just a few basics - food, light and water. When you’re an alga spore, the light and water are pretty easy to come by in a swimming pool but food is a bit more complicated because the pool-owner can control.

"Phosphate removers should not be used to clear an existing algae bloom since the oxidation of algae will release additional orthophosphate. Use them after clearing algae from a pool." In other words, a solid one-two punch to clear an existing algae bloom is to shock with chlorine, and follow it up with a phosphate remover like PR, Glucosephosphate utilization by marine algae.

Blue-green algae have a high protein, iron, and other mineral content which is absorbed when taken orally. Blue-green algae are being researched for their potential effects on the immune system. Abstract. The growth response of Anacystis nidulans to sodium and phosphate was studied in batch culture under controlled laboratory conditions.

Sodium (range=0–10 mg/l) significantly enhanced growth, most notably, after sodium and phosphate starvation. The magnitude of the increase in growth was dependent on the initial cell density, external concentrations of phosphate, sodium, and.

The usage of blue-green algae (BGA) started in early twentieth century, but recent understandings of cellular and metabolic diversities of BGA have given a new hope in wastewater treatment.

One of the studies (Nitrate and phosphate levels positively affect the growth of algae species found in Perry Pond., STEFFII FRIED, BRENDAN MACKIE, and ERIN NOTHWEHR, Biology Department, Grinnell College, Grinnell, IAUSA) he referred to states, "As expected, nitrate and phosphate levels both significantly affected algal growth.

These results are supported by Ryan et al. The organic phosphate is the phosphate that is bound or tied up in autotrophs, waste solids, or other organic materials.

After decomposition, this phosphate can be converted to orthophosphate. Algae and plants are the key elements to passing on phosphates to other living organisms, but their importance in phosphorus cycle is connected mainly to. Algae and cyanobacteria in fresh water T he term algae refers to microscopically small, unicellular organisms, some of which form colonies and thus reach sizes visible to the naked eye as minute green particles.

These organisms are usually finely dispersed throughout the water and may cause considerable turbidity if they attain high densities.Algae - Algae - Evolution and paleontology of algae: Modern ultrastructural and molecular studies have provided important information that has led to a reassessment of the evolution of algae.

In addition, the fossil record for some groups of algae has hindered evolutionary studies, and the realization that some algae are more closely related to protozoa or fungi than they are to other algae.The blue-green algae are most frequently involved in the con­tamination of water supplies, but the greens, the flagellated golden-brown, and the diatoms are also troublesome at times.

Mention may be made of Prymnesium parvum, Gymnodinium veneficum and Microcystis spp. which cause mortality of fish and domestic animals that drink water infested.
