Abstract
The aim of the study was to clear the effect of inactivation of Verticillium dahliae and Fusarium oxyporum f. sp. melonis of crops pathogenic fungi under methophilic (35°C) and thermophilic (55°C) temperatures using batchwise anaerobic digesters. The time required for a 90% reduction of viable counts of a population of microorganisms or a decrease by log10 (T90) of Verticillium dahliae was 7.7 days at 35°C and 0.6 days at 55°C, respectively. The T90 value of Fusarium oxyporum f. sp. melonis was 0.5 days at 35°C. However, Fusarium oxyporum f. sp. melonis could not be detected after 15 minutes at 55°C. As a result, it was clear that thermophilic digestion was more effective in inactivating Verticillium dahliae and Fusarium oxyporum f. sp. melonis than methophilic digestion.
