Bioterrorism is use of infectious agents or other harmful biological or biochemical substances i.e. from biological source as weapons of terrorism. It is intentional release or dissemination of biological agents. These agents are bacteria, viruses, fungi, or toxins, and may be in a naturally occurring or a human-modified form.
Fungi are important in various facets. Fungi degrade/ decompose complex plant and animal remains, breaking them down to simpler chemical compounds which on addition increases fertility of the soil. They are also important in industrial fermentation. Some fungi are used in processes aimed at reducing the concentrations and toxicities of waste materials particularly from industrial processes, before releasing waste to environment.
Mycotoxins are defined as natural products from molds that evoke a toxic response when introduced in low concentrations to vertebrates. These are toxic compounds produced as metabolic products by some molds.
They are products of secondary metabolism of molds i.e. part of metabolism that is not essential for cell growth and maintenance of basic cell functions.
