A secondry metabolite which primarily acts as a toxin is
Answers
Roux and Yersin (1888) who first observed the presence of toxin in a disease caused by Corynebacterium diphtheriae. Gaumann (1954) stated "micro-organisms are| pathogenic only if they are toxigenic". He used the term "toxin" and "microbial poison" to denote all substances produced by the pathogens. Therefore, there is a correlation between toxin and development of disease, resulting in the death of hosts. Toxins interrupt the metabolic processes of the living host cells.
Answer:
When secreted those poisonous compounds are known as exotoxins whereas those found in the prokaryotic cell wall are endotoxins. An example of a bacterial secondary metabolite with a positive and negative effect on humans is botulinum toxin synthesised by Clostridium botulinum.
