The reduction of TTC (2,3,5-triphenyltetrazolium chloride) to TPF (triphenylformazan) in submerged soils was investigated. In terms of nmol TPF per g of dry soil per 30 min, the amounts of TTC reduction in soils after 1 to 28 day incubation under submerged conditions at 30℃ in the dark were 0-749 for the Nagano sample and 0-216 for the Nyuzen sample, indicating and increase with the time of incubation. γ-Ray irradiation with cobalt 60 at a dose of 3 Mrad which almost completely sterilized soil microorganisms decreased TPF formation in the Nagano and Nyuzen samples by 62 and 57%, respectively. After γ-ray irradiation a linear correlation between the assay time and the amount of TPF was observed. The rate of enzymatic TPF formation in the Nagano sample after γ-ray irradiation was the same as that of the Nyuzen sample. The estimated percentages of TTC reduction in submerged soils were 68-76% for dehydrogenase activities and 24-32% for highly reducing substances.
