Penicillium from fungi is mixed with sugar in a fermenter. Fungi grows for about 15-24 hours and then begins to secrete penicillin. The solution is filtered off and is concentrated to give penicillin. Enzymes lipase in biological washing powders are used to break down fats or grease on clothes and protease used to break down proteins such as blood stains.
Microorganisms like Penicillium fungi are grown in fermenters where they produce penicillin. The same process can be used to produce enzymes for biological washing powders. The organisms are grown in a controlled environment within the fermenter, allowing for large-scale production of these substances.
