Production of penicillin antibiotics
In the microbiology industry, penicillin and other antibiotics are very impressive. The annual production of penicillin is approximately 33,000 metric tons, with a market share of over $ 400 million . Annual sales of raw materials on a global scale from four Group Top of penicillin antibiotics, cephalosporin , tetracycline  and erythromycin , 2.4 billion dollars in America have been reported.
In the early 1940s by Alexander Fleming isolated the fungus Penicillium Nvtatvm , respectively. He observed the cellular components autolysis medium Staphylococcus aureus  themselves from ruin. Today, penicillin is produced with better mildew components. The development of submerged culture media, which is a mushroom in aqueous solution, increases the cultivation of large-scale mushrooms through the application of sterilized air.
- Streptomycin  produced by actinomycetes 
- Molasses, corn syrup, sugar industry remnants, and wet corn mills are used to produce penicillin.
- Penny Sylyvm Krysvjnyvm  can produce 100 times more than the medium Fleming.
The main steps in the production of penicillin are:
- Inoculum preparation
- Prepare and sterilize the environment
- Intrauterine insemination
- Compulsory aeration with sterilized air during incubation
- Remove the growth of mold and fungus after fermentation
- Extraction and purification of penicillin
