The following table shows some examples of bacterial strains with bioactivity and the sources where they were obtained. (credit: modification of work by National Oceanic and Atmospheric Administration) An algal bloom is a massive population explosion of free-floating, phototrophic organisms, often composed of dinoflagellates, that usually occurs from an influx of nutrients, specifically nitrogen and phosphorus. Some species of algae release toxic compounds into the water. There are many types of algae. However, these are some of the more prominent types: Also called Rhodophyta, it is a distinctive species found in marine as well as freshwater ecosystems. The pigments phycocyanin and phycoerythrin are responsible for the characteristic red colouration of the algae. Get a free home demo of LearnNext. Algae, also called cyanobacteria or blue-green algae, are unicellular or multicellular eukaryotes that obtain nourishment by photosynthesis. Some are harmful to man while others are good for man and environment around. There are two main categories of algae: microscopic single-celled microalgae, and larger, multi-celled macroalgae. Algae are very important because they make much of Earth’s oxygen, which humans and other animals need to breathe. Collectively algae, protozoa, and some lower fungi are frequently referred to as protists (kingdom Protista, also called Protoctista); some are unicellular and others are multicellular.

Algae is one of the most efficient sources for creating biofuels, … Microorganisms play important role in our day today's life. Most of microorganisms are helpful to us. They are helpful in many ways. Some examples... Bio-flocculation, induced by microorganisms such as bacteria, flocculating microalgae, and fungi, can contribute to the accumulation of dense algae, reducing cell dilution, and ultimately increasing harvesting efficiency [79, 80]. It is believed that cyanobacteria are the origins of green land plants. Biological sources of nanoparticles comprise different macroorganisms and microorganisms, such as plants, bacteria, fungi, algae, and seaweed. Algae and protozoa are examples of protists. There are different types of microorganisms like 1. Microorganisms in a hot environment : Algae growing in a hot pool in New Zealand. Some algae, such as seaweed, look like plants. It possesses variable shapes as given in the diagram below: Distribution: Worldwide. Bacteria 2. The term algae implies a variety of plantlike organisms.
