In the present paper, some experiments are described on enzyme systems of Bacterial Viruses. The purified high concentrated S. gallinarum (Akita strain) phage (abbrebiated Sg Bp) was used as enzyme preparation, and the enzymatic activity of Bacterial Viruses was widely reserched by Warburg apparatus, Thurnberg tube, Absorption spectrum and other enzymatic methods. The findings obtained are summarized as follows.I) We have made clear with the absorption spectrum analysis the catalase activity of Sg phage is taken place by the Hematin like substance, but it is very difficult to prove the catalase activity is to be the activity of phages itself or hosts itself.2) It appears that Sg phage has no enzymatic activity e.g. Raspiratory enzymes, Enzymes in Carbonhydrate metabolism (contains Enzymes in TCA Cycle), Transacetylase, Transaminase, Desmolase, Amino Acid Oxydase, Amino Acid Decarnoxylase etc.
