What Is Characteristics And Economic Importance Of Cyano Bacteria?
Characteristics of Cyano Bacteria: The cyano bacteria are the largest and most diverse group of photogenic bacteria which was previously known as Blue green algae. Cyano bacteria are true prokaryotes. They vary greatly in shape and appearance. They range in diameter from about 1-10 um and may be unicellular, exist and colonies of many shape, or form filaments consisting of trachoma’s surrounded by new mucilaginous sheath. They have normal gram negative type cell wall. They lack flagella and often use gas vesicles to move in the water and many filamentous species have gliding motility. There photosynthesis system closely resembles that of eukaryotes because they have chlorophyll and photo system. They carry out oxygenic photosynthesis. They use water as an electron donor and generate oxygen during photosynthesis. Reserve food material in cyano bacteria is glycogen. Cyano bacteria reproduce by binary fission, fragmentation. In cyano bacteria formoginia, akinetes and heterocyst are presen
