Identity of Cyanobacterial Toxins Cyanobacterial toxins are toxins produced by cyanobacteria‚ or blue-green algae. They include neurotoxins (e.g.‚ anatoxins)‚ hepatotoxins (e.g.‚ microcystins)‚ skin irritants and other toxins. Both hepatotoxins and neurotoxins are produced by cyanobacteria commonly found in surface water supplies and therefore appear to be of most relevance to water supplies at present.1-3 However‚ the neurotoxins are relatively unstable and‚ as such‚ are not considered to be as

Cyanobacteria including those that form stromatolites There have been many technological advances that have lead to a greater understanding to the world that we live in‚ especially over the past 50-75 years. Developments in technology such as the light microscope and the transmission electron microscope particularly have made research in the field of bacteria and in this case Cyanobacteria much easier‚ removing barriers and creating a situation where there are barley any limits.

ALGAE Algae are eukaryotic organisms that have no roots‚ stems‚ or leaves but do have chlorophyll and other pigments for carrying outphotosynthesis. Algae can be multicellular or unicellular. Unicellular algae occur most frequently in water‚ especially in plankton.

Premium Algae
Algae are simple organisms that typically produce their own food through photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very

Green algae have many similarities to land plants. It has many variety body types and the multicellular forms do not have cells separated into tissues‚ which is what divides green algae from land plants. Green algae are a very diverse group of freshwater algae. Many green algae form long filaments. The cells stay attached after they divide. Spirogyra can become so numerous they form dense mats of growth in surfaces of ponds‚ which is called pond scum. This pond scum is interesting to see through

need an oil alternative‚ which is both economically friendly‚ and environmentally friendly. Algae farming tends to fall in both of these categories; what’s more‚ it is also efficient. For three very important rationales‚ I stand in a strong affirmation for this bill‚ in which we will fund algae farming. First off‚ Algae farming can be farmed realistically anywhere. There are very few requirements for algae biofuel. All biofuels that are created from land plants have specific soil-quality requirements

take long before we have used up all of what we have become so dependent upon. That is why the world is looking at a new source of energy. A very small and unexpected source that most would not even have considered an option; algae. Using biodiesel fuels harvested from algae is not only helpful for the environment‚ but is a smarter way to produce alternative energy‚ save money‚ create jobs and eliminate America’s dependency on foreign oil. The use of biodiesel fuel has been around since the beginning

used three different species of algae‚ Macrocystis (brown)‚ Plocamium (red) and Ulva (green). Before we conducted anything‚ we first measured the initial oxygen concentration in the water that was used to house each alga. This was done because in the water that we used there happened to be phytoplankton which can respire and photosynthesize. If we didn’t take them into consideration our results would end up skewed. Once that was known we took a piece of each algae that had a surface area of 39.26
