CYANOBACTERIA

CYANOBACTERIA

Commonly known as blue-green algae or blue-green bacteria, cyanobacteria is a bacterial phylum that acquires energy through photosynthesis. As a result, the fundamental environmental conditions required for photosynthesis are needed for this type of bacteria to survive. Encompassing marine to terrestrial habitats, this bacterium may be found in a myriad of environments.

TYPES

 

Chroococcales

Two main classes (Chroococcaceae and Entophysalidaceae) consist of this order.

Members of Order Chroococcales even have the subsequent characteristics:

  • A spherical, ovoid or cylindrical cell shape structure
  • As they mature, they coalesce to make colonies that are held together by a slimy matrix
  • They could occur individually following cellular division

 

Other members of Order Chroococcales include:

 

  • Pleurocapsales
  • Aphanocapsa
  • Gloeocapsa
  • Merismopedia
  • Microcystins
  • Pleurocapsa

 

All of them reproduce through multiple fission in addition to releasing endospores. These are just some of the unifying characteristics of Order Pleurocapsales. The main distinctive factor compared to other organisms that also form endospores is that members of Pleurocapsales divide through binary and multiple fission. To release additional endospores, a number of the cells within the mass undergo multiple fission. Encompassing terrestrial and marine environments, this order is additionally composed of a wide range of organisms that may be found in an array of habitats.

 

Order Pleurocapsales members include the following:

 

  • Xenococcus
  • Dermocarpella
  • Pleurocapsa
  • Chroococcidiopsis

 

 

Oscillatoriales

 

Order Oscillatoriales are characterized by filiform blue-green algae, but for some reason, members of this order lack true heterocysts, akinetes, and branching.

 

From freshwater and saline water bodies to terrestrial habitats, members of this order are often found in a myriad of environments.

 

Other traits of this order include:·

 

  • They have threadlike structures
  • They tend to develop multicellular elongated structures

 

Members of Oscillatoriales include:

 

  • Lyngbya
  • Planktothrix
  • Phormidium
  • Microcoleus

 

Nostocales

Order Nostocales’ members have a heterogeneous cellular composition in their trichomes.

Falsely branching in some species is a common trait for this order.

 

A few members of this Order include:

  • Calothrix
  • Anabaena
  • Nostoc
  • Cylindrospermopsis

 

Stigonematales

Members of Order Stigonematales have similarities with Order Nostocales.

Multiseriated filaments with true branching are just some of the other traits related to the order Stigonematales.

 

The following includes the members of this order:

  • Mastigocladus
  • Stigonema

 

Gloebacterales

These organisms can be found in different kinds of environments such as limestone rocks and other aquatic environments. Light-harvesting complexes known as phycobilisomes are consumed gloebacterales.

 

SYMPTOMS

 

Common signs and symptoms include the following:

  • Cold or Fever
  • Diarrhea
  • Vomiting or nausea
  • Weakness
  • Pilo-erection
  • Death

TREATMENT

 

Prevention is always better than looking for a cure.

Water used for drinking and cooking should not contain any toxins. To make sure that such water is clean and free from toxins, you may boil it to ensure safety. However, boiling water is not generally suggested because it could increase the effects of the toxic substances in there.

 

Treating an infection depends on the type of cyanobacteria and infection you have.

 

The following treatments are available:

  • Use of antibiotics
  • Use of medicinal drugs like cholestyramine
  • Vitamins
  • Oxygen therapy
