A biofertilizer is a substance that holds beneficial microorganisms for plant growth in a carrier material. To demonstrate the effect of -sterilization, the survival of the was monitored to assess the shelf life of biofertilizers. As biofertilizer carriers, five kinds of typical Japanese soil-based materials were used. Following the sterilization of carrier materials by -irradiation or autoclaving, was inoculated into each material. The biofertilizer was stored for 12 months at 4C or 30C. After storage, viable inoculants in the biofertilizer were enumerated. Results indicated that inoculant density after storage was greater than the initial density in biofertilizers made from sterilized carriers, whereas it decreased significantly in biofertilizers made from non-sterilized carriers. -sterilization was superior to autoclave sterilization in enhancing inoculant survival in some cases.

The Effect of -sterilization of biofertilizer's carrier on bacterial inoculants survival

Biofertilizer is a substance that holds beneficial microorganism for plant growth (e.g. Rhizobia) in the carrier such as peat, perlite, charcoal and soil. To use biofertilizer more efficiently, it is necessary to keep the amount of viable inoculants in the biofertilizer for a definite period of time. The inoculants survival in the biofertilizer could be affected by the physical and chemical properties of carrier materials and by the competition with native microorganisms in the carrier. -irradiation is expected to sterilize the carrier materials without changes in physical and chemical properties. In an effort to demonstrate the advantage of -sterilization, the survivals of inoculants were monitored to assess the shelf life of biofertilizer.
