CYANOBACTERIA

CYANOBACTERIA

• Also known as Blue-Green Algae
• Equipped to use the sun's energy to manufacture their own food through photosynthesis
• Tend to proliferate in very slow moving or still fresh water

Microscopic picture

HOW IT REPRODUCES

• There is the vegetative reproduction
• There is asexual reproduction

VEGETATIVE REPRODUCTION

• Fission: Unicellular cyanobacterial cells divide and reproduce by fission
• Fragmentation: filaments break down into small pieces and each piece develops into a new colony
• Hormogonia: filaments break into pieces or trichomes, which are called hormongonia and develop into new filaments

ASEXUAL REPRODUCTION

• Endospore: one or more cell increase in size and their protoplasm divides in many parts to form endospore
• Exospore: these structures are formed in the distal part of the protoplasm
• Akinetes: these are formed close to the heterocysts. Cells increase in size and thick layer is formed around it. They give rise to new filaments

CONTINUED

• 4. Nannocytes: cells may divide into many parts without any change in shape. In so this way so many bodies are formed

IT CAUSES...

• If fish is ingested or water is swallowed while swimming can produce nausea, vomiting fever, and diarrhea
• Eyes can also be irritated
• These systems can be more exacerbated in children

CONTINUED

• This is because the toxin-to-body-weight ratio is higher in children than in adults
• Liver damage can result in children exposed to the toxins

ANTIBIOTICS

• Microcytis aeruginosa
• Aphanizomenon gracile
• Chrisosporum bergii
• Planktothix agradhii

TRANSMISSION

• In warm, nutrient-rich environments, microscopic cyanobacteria can grow quickly
• It starts creating blooms that spread across the water's surface and may become visible

BENEFICIAL

• It contains small amounts of protein, vitamins (including C, E, and folate), beta carotene, and some minerals
• But unless you eat huge amounts of algae, they are a negligible source of nutrients
