Thermolabile triose phosphate isomerase in a psychrophilic Clostridium.It was found that a psychrophilic Clostridium contains a triose phosphate isomerase which is very labile at moderate temperatures. An investigation showed that the optimal growth temperature of the psychrophile was between 15 and 20 deg C. No growth occurred at 25 deg C. The thermostability of the glycolytic enzymes in the cell-free extracts of Clostridium sp. strain 69 was studied. The data obtained show that the triose phosphate isomerase is quite labile at moderate temperatures. The instability of the enzyme is sufficient to explain the low maximum growth temperature of the psychrophile.
