The Algae Bloom Process

3. Algae bloom process the microbes involved in
Algae are a diverse group of photosynthetic microorganisms, which vary from small, single-celled microbes to complex multicellular forms. Though algae bloom is considered as natural phenomena, but nutrient pollution can increase their frequency, duration and intensity. After getting adequate nutrition, the algae can grow rapidly in warm and slow moving water. The rapid increase in number causes the bloom to turn water noticeably green, but other colours can also be observed. The gelatinous coating of some algae helps it to float in water by allowing cells to stick together. Some algae form thick mats to float on the surface. Lake Erie also has a rich diversity of benthic algae.

The mycrocystin toxin was produced by the blue-green algae in the Lake Erie. Phosphorus load from the Maumee river was the main source of nutrients for the cHAB growth in the lake. Again, the agricultural area of the watershed also contributed for the phosphorus load in the lake. Nitrogen loading also helped in the algae bloom during that period. Remote sensing tool using satellites used for detection of the algae bloom at Lake Erie (shown in Figure 3). NOAA (National Oceanic and Atmospheric Administration) Lake Erie Experimental HAB Bulletin and associated Experimental HAB tracker helped to model the algae bloom and comparison with the field …show more content…
There has been very limited research conducted on the cyanotoxins and cyanobacteria produced bioactive compounds. The important research areas are- (a) Modeling tools for predicting and preventing harmful algae blooms, which include all environmental and anthropogenic factors to predict and prevent algae blooms, (b) Mitigation and control strategies for algae bloom after identifying chemical, physical control processes, mitigation processes and economic feasibility, (c) HAB toxin is an emerging research topic, which includes identifying and studying less common mycrocystin producers and studying harmful toxins, e.g. saxitoxin, anatoxin-a, cylindrospermopsin, nodularin. Identifying and evaluating the fate and effects of harmful algae bloom on animal and human health, along with the freshwater ecosystem is very

    The further downstream processes involve separation and washing to obtain pure biodiesel. (Demirbas and Fatih Demirbas 2011) Algae to oil process is simple alternative to produce biofuels. Naturally occurring algal species does not give economically feasible yield for microalgae oil. Thus scientists have developed genetically engineered species of microalgae to maximize the yield of oil produced. The advantages of algae oil are listed in the introduction part which clearly show that advances in algal biofuel production is the need of the…

    Algae contribute to about half of all oxygen production(Chapman, 2013). They are photosynthetic, meaning that they produce their own food from sunlight, water, and nutrients, and are usually found in any water habitat(Smithsonian, 2016). The fact that algae produce oxygen is important because dissolved oxygen is very important to the health about of a water body(Water properties: dissolved oxygen, 2016). Human activity runoff is a major source of water pollution(Runoff, 2016). Runoff can pick up chemicals, fertilizers, spilled gasoline, and other toxic substances from urban, suburban, or large rural areas, and deposit them into the water, which contaminates the water(Runoff, 2016).…

    The joint Genome institute states that Daphnia typically feeds on Algae and Bacteria, they are also an indicator species to environmental change. They occupy a crucial position in food webs. Daphnia also live in both deep lakes and shallow ponds. In the scientific journal Ecology, Etymology and evolution and parasitism in Daphnia by Dieter Ebert 2005 it is stated that Daphnia are asexual. Planktivorous fish feed on Daphnia also Glassworms are known to feed on Daphnia.…

    Next are the two High Rate Ponds, Inner, and Outer, which shallow ponds that are constantly churned with paddles. Most of the algae growth occurs here because all of the nutrients are mixed together, making it easier for algae to get the food they need. By the time the water leaves these ponds, all the contaminates are gone and only algae is left. After those the two ponds go back into one in the Algae Settling Pond. All the algae that has grown settles out to the bottom of this pond, and after all the algae settles the clean water is then drained into another pond.…

    Some abnormal behaviors from species including clown fish and sea snails were observed swimming toward predators. The pH of the solution is lowered by introducing carbon dioxide into the solution. Another great feature about the mesocosm technology other than predicting impact on organisms is that it can be relocated to different ecosystems throughout the world’s oceans. One of these mesocosms was installed in the Swedish Gullmarn Fjord near Kristineberg,…

    This article interested me because it brings some hope that some corals are still able to survive in low pH conditions. It also brings some hope to this issue of ocean acidification. It is crucial that we find ways like new energy sources to stop the pH of ocean decreasing. It is important because corals are very important for other organisms and are a keep component in marine life stability. This just shows that because of carbon dioxide in the atmosphere organisms that are helpful are dying and being negatively affect, thus affecting the food chain and mainly affecting humans.…

    Firstly, “algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment” (Moroney et al. 2009). This is important because excess carbon dioxide in the environment causes warming effects, which is harmful to the atmosphere. Furthermore, algae are an accurate indicator of water pollutants and water quality in general. “Because of their nutritional…

    The biotic changes are what species or organisms remain after a natural or human-caused disturbance; the species diversity such as fish, shellfish, and bird that can be measured. In addition, vegetation such as algae that produces chlorophyll E can determine how much algae is the water (NOAA, 2011). Unfortunately, whether it is a natural or human-caused disturbance, it can result in complete destruction and loss of an estuary habitat permanently disrupting abiotic and biotic…

    Effects of PGPRs on the seeds have been realized first time inoculated with Pseudomonas spp. which was isolated from roots. Various studies have been conducted to figure out the influence of PGPRs on plant but very few have considered parameters of seed germination along with plant growth. Plants inoculated with PGPRs give improved growth and resist these stresses significantly better than the uninoculated plants under stress conditions (Kloepper et al. 2007) They also produce different antibiotic compounds which inhibit the proliferation and propagation of plant pathogens (Mazurier et al.…

    In this study, the effects of both varying temperatures and light intensity upon the photosynthetic rate of spinach leaves were observed. Using the ‘spinach immersion’ technique, the rate of photosynthesis under various conditions was quantified by observing the amount of spinach floating on top of a sodium bicarbonate solution. The sodium bicarbonate solution simultaneously supplied the spinach with carbon dioxide for use in photosynthesis, and caused it to sink. When the leaf underwent photosynthesis and produced oxygen gas, the leaf floated to the surface. It was hypothesized that an increase of either temperature or light intensity would lead to an increased rate of photosynthesis, to a degree.…
