Abnormal fermentation in natto production (without mucilage) was investigated and the cause was recognized as phage infection. The existence or non-existence of phages was ascertained in various commercial natto and phage infections were recognized only in bad or in no mucilage-forming natto products. When phages were mixed with B. natto and incubated, the inhibition of mucilage formation was confirmed. The phages which invade B. natto are also found extensively in nature, in natto producing factories, in soil, in sewage sludge, etc.Twenty one strains of B. natto phage which were isolated were classified by host range into 4 groups and serologically into 3 groups. These isolated phages were designated as PN and some properties of the PN-3,PN-6,PN-19 phages were examined.
