The most frequently repeated environmental concerns are toxic algae blooms, introduction of alien species and issues related to climate change.
Important technical groundwork was done by Professor Thomas Brück and his team at the Algae Cultivation Center of the Technical University of Munich.
Rapid decomposition of dead algae reduces the dissolved oxygen concentration and pH and increases ammonia and carbon dioxide concentrations.
In fact, some of the chemical syntheses that simple plants and algae can accomplish far outstrip human technologies.
To meet this goal, it's been pouring money into algae, sugar and other crops that could become alternatives to fossil fuels.
All water treatments involve the removal of solids(usually by filtration and sedimentation), bacteria, algae and inorganic compounds.
Plants and cyanobacteria(also called blue-green algae), she says,"have evolved highly organized photosynthetic systems for the efficient oxidation of water.".
There is evidence in the scientific literature that some algae and cyanobacteria are capable of absorbing metals into their cells.
(iii) Algae and algal products: This is another apparent oxymoron, yet an opportunity for arid drylands' people.
On these farms, the ocean will be grown not only fish, but also algae, which will be used for food and fuel.
The PNNL technology harnesses algae's energy potential efficiently and incorporates a number of methods to reduce the cost of producing algae fuel.
In addition, it will not promote algae, bacteria or fungi growth, with a life span of 50 years.
Therefore, no scientific basis for assuming that algae and cyanobacteria can play an effective role in the bioremediation of environment polluted by oil.
For example, capture fisheries, algae farms and aquaculture may compete for ocean space in coastal areas.
Algae are grown in drylands in greenhouses or in other devices that prevent evaporation and enable circulation of water.
The chemical culprits are two compounds that are produced by blue-green algae, especially in warm weather(geosmin and methylisoborneol).
One of the species had entire plots that got wiped out, and they were overgrown with algae,” Clements said.
In addition, it will not promote algae, bacteria or fungi growth, with a life span of 50 years.
Algaecides are chemicals that kill algae and blue or green algae, when they are added to water.
These algae were eaten by single-celled micro-organisms, which also grow in salty water and produce a polymer that can be used to manufacture bioplastics.
