In 1927 he changed over to physics and took his doctor's degree in 1928 under Professor Enrico Fermi. He served in the Italian Army in 1928 and 1929.

REVIEW

Thermostable enzymes and their industrial application: a review

Md. Fakruddin

Enzymes produced by hyperthermophilic microorganisms are stable at high temperature. Most of the hyperthermophiles are Archaea but there are two groups of bacteria: Thermotogales and Aquificales. Activity of thermostable enzymes can be at temperature close to the organism's growth temperature or at above the organism's growth temperature or can be below the organism's optimum growth temperature.
