The document discusses antibiotics, detailing their role as drugs for bacterial infections and their ineffectiveness against viruses. It highlights the discovery of penicillin by Alexander Fleming in 1926 and the subsequent Nobel Prize awarded in 1945 for its development. Furthermore, it outlines the fermentation process used for large-scale antibiotic production while emphasizing the importance of maintaining sterile conditions to prevent contamination.

microorganism that inhibits the grow of
another.

penicillin.
• In 1939, Edward Chain and Howard Florey

15. • Although most antibiotics occur in nature, they
are not normally available in the quantities
necessary for large-scale production.
• Antibiotic For this reason, a fermentation
process was developed. It involves isolating a
desired microorganism, fueling growth of the
culture and refining and isolating the final
antibiotic product. It is important that sterile
conditions be maintained throughout the
manufacturing process, because contamination
by foreign microbes will ruin the fermentation.
