Topic: Historical Timeline of BIO-02 Discoveries
1857: Louis Pasteur demonstrates that fermentation is caused by living microorganisms (Saccharomyces), not spontaneous chemical reactions. This establishes the field of microbiology.
1876: Robert Koch establishes germ theory of disease and develops pure culture techniques. These methods enable all subsequent industrial microbiology.
1928: Alexander Fleming discovers penicillin from Penicillium notatum. Observes mold contaminating bacterial culture plates was dissolving Staphylococcus colonies. Publishes the finding in 1929.
1940s: Howard Florey and Ernst Chain (Oxford University) purify penicillin and demonstrate clinical efficacy. Industrial production begins using Penicillium chrysogenum. Penicillin becomes the first mass-produced antibiotic during World War II (saving millions of lives).
1943: Albert Schatz and Selman Waksman (Rutgers University) discover streptomycin from Streptomyces griseus. First antibiotic effective against tuberculosis (Mycobacterium tuberculosis). Nobel Prize to Waksman in 1952.
1950s-1970s: Golden age of antibiotic discovery from Streptomyces species: tetracycline (1948), erythromycin (1952), vancomycin (1958), and many others. Most modern antibiotics originate from soil actinobacteria.
1972: Jean-François Borel (Sandoz AG) discovers cyclosporin A in extracts from Trichoderma polysporum cultures. First clinical trials in organ transplantation begin in 1978.
1976: Akira Endo (Beecham Research Labs) discovers the first statin — compactin (mevastatin) — from Penicillium citrinum. Lovastatin from Monascus purpureus identified shortly after.
1980s: Cyclosporin A approved for clinical use in organ transplantation (1983, US FDA). Revolutionizes transplant medicine — 5-year kidney survival rates approximately double.
1987: Lovastatin (Mevacor) approved by FDA as the first commercial statin. Begins the era of statin therapy for cardiovascular disease prevention.
1996: First Bt transgenic crops (Bt maize, Bt cotton) approved for commercial cultivation in the USA. Bt cotton introduced in India in 2002; now covers >90% of cotton acreage.
