Cyanobacteria have a variety of cell types, cellular structures, and physiological strategies that contribute to their ecological success in the plankton, metaphyton, or periphyton. Diazotrophic cyanobacteria have evolved several strategies with different degrees of complexity to protect their nitrogenase from oxygen, which is present in the surrounding medium and also produced intracellularly. Species are Lyangbia can be used in the preparation of antibiotics. commonly known as "swimmer's itch.". Cyanobacteria are very important organisms for the health and growth of many plants . Cyanobacteria, also known as blue-green algae, blue-green bacteria or Cyanophyta, is a phylum of bacteria that obtain their energy through photosynthesis. It releases oxygen and uses water as an electron-donating substrate, i.e. Cyanobacteria like Spriulina are cultivated in tanks as a protein rich food for fish and other animals. larger cells among the filaments of Nostoc, shown at right. They form symbiotic association with protozoa fungi and plants.The nitrogen fixation species form association with angiosperms.They … They exhibit several types of chromatic adaptation, regulated at transcriptional and postranscriptional levels. Other than this, they are also capable of … Most recent studies have gleaned novel insights into the ecological importance of Antarctic cyanobacteria by applying so-called multi-‘omics’ technologies. They exhibit several types of chromatic adaptation, regulated at transcriptional and postranscriptional levels. Hence, they are of great importance in aquaculture. to house the bacteria, in return for organic nitrogen. They help in the reclamation of alkaline soil. Species of Nostoc and Anabana help in nitrogen fixation. In tropical countries, it may be a very important part of the diet, and was Some plants have evolved to form symbiotic relationships with it, with cyanobacteria residing within the plant roots. involved. Here, we provide a comprehensive description of the attempts to identify mechanisms of PCD and the existence and importance of OCAs based on in silico approaches.
