| OtherInfo | One of the first two women to be elected a Fellow of the Royal Society.
Distinguished as a biochemist particularly in the field of bacterial metabolism with her publication Bacterial Metabolism (1930) becoming a standard textbook for microbiologists.
Basing her work mainly on the study of "resting" bacteria she was able, with Quastel, to throw new light on the metabolism of anaerobic organisms. Later she discovered the enzyme hydrogenase, which activates molecular hydrogen, and studied its reactions. She showed that Bact coli can develop an enzyme (hydrogenlyase) which decomposes formic acid to carbon dioxide and hydrogen, and was led by this discovery to contribute further to the general problem of adaptive enzymes.
Advanced knowledge of bacterial deamination. |
