Bacteria and Cyanophyta Adverse

Adverse Role of Bacteria


  1. Food spoilage. For example, Clostridium botulinum.
  2. The cause disease in humans. For example Mycobacterium tuberculosis (the cause of tuberculosis), Vibrio cholerae (cholera causes or vomiting), Clostridium tetani (tetanus causes), and Mycobacterium leprae (leprosy causes).
  3. The cause of the disease in animals. For example, Bacillus anthracis (cause of anthrax in cattle).
  4. The cause of disease in the crop. For example Pseudomonas solanacearum (cause diseases on tomatoes, capsicum, eggplant, and tobacco), and Agrobacterium tumafaciens (causes tumors in plants).


The role of Cyanophyta Adverse

Cyanophyta are detrimental to humans is actually related to human actions as well. Cyanophyta can live in an environment with high levels of phosphate and nitrogen are high. Phosphate and nitrogen levels are higher in a water environment pollution is often caused by industrial and agricultural waste.

Environmental conditions can thus lead to the growth of Cyanophyta in abundance. Cyanophyta abundance of waters may cover the surface so the sunlight and oxygen needed types of organisms in the water is reduced. In addition, an abundance of Cyanophyta produce toxins that can kill many kinds of fish and other aquatic organisms
