Tetracuccus soyae is halo-tolerant, gram-positive, and tetrad forming cocci which, is considered to be a lactic acid bacterium. When grown under aerobic conditions, the catalase activity of Tc. soyae is strengthened.The present investigation was undergaken in order to study factors affecting its catalase activity, and the type and characteristics of the catalase.The following results were obtained : 1. The catalase of Tc. soyae is of a hem-type and sensitive to hem poisons, cyanide and azide, but insensitive to a metal chelate compound EDTA.2. Both sugar concentration and metal ion (Fe, Mn) did not affect its catalase activity strongly.3. Relationship between the catalase activity and the utilization of glycerol was not observed.4. The optimum pH and the optimum temperature for the catalase are within ranges of 6-8,and 55-60℃. Its enzyme is halotoletant.
