Explain giving specific fungal species. The penicillins are actually a class of antibiotics. Explain whether penicillins are bacteriostatic or bacteriocidal. Give an example of an important enzyme that is produced from fungi and used in food production. Fungi play two different roles in cheese production, one in an early stage and others in the late stages.
Fungi play important roles in the production of steroids.
Explain whether a single fungus usually produces a steroid drug or not. Name one species in this genus. Amanitin, phalloidins, aflatoxin and ergot compounds are all considered to mycotoxins. What fungi produce these compounds and how do they affect people. Amanitins and phallotoxins are similar in structure and toxicity when injected into mice.
