BIOXII10: MICROBES IN HUMAN WELFARE

Ernest chain and Howard Florey's contribution was:
1 Discovery of Streptokinase
2 Discovery of DNA sequence
3 Establishing the potential of penicillin as an effective antibiotic
4 Production of genetically engineered insulin
Explanation:
Penicillin was the first antibiotic to be discovered by Alexander Fleming (1928). He found that fungus Penicillium notatum or its extract could inhibit the growth of bacterium Staphylococcus aureus. However, its full potential as an effective antibiotic was established much later by Ernst Chain and Howard Florey. This antibiotic was extensively used to treat American soldiers wounded in the World War II. Fleming, Chain and Florey were awarded the Nobel prize in 1945, for this discovery.

Identify the bacteria and fungi which was growing on in the culture plate which were plated by Alexander Fleming?
1 Staphylococci, Penicillium notatum
2 Streptococci, Penicillium notatum
3 Staphylococci, Saccharomyces cerevisiae
4 Streptococci, Saccharomyces cerevisiae
Explanation:
Alexander Fleming while working on Staphylococci bacteria, observed a mould growing in one of his unwashed culture plates around which Staphylococci could not grow. \(\mathrm{He}\) found out that it was due to a chemical produced by the mould and he named it Penicillin after the mould Penicillium notatum
