English Abstract

This study was conducted to evaluate the effect of storage conditions of the shelf life of Trichoderma viridi and Bacillus megaterium, T.

Viridi gave the highest colony forming unit (CFU) in 4oC up to 210 days after inoculation.

The maximum value of 3.8 x 108 CFU/g was calculated after 15 days of incubation in both temperature, and 210 days after inoculation 4 x 104 and 1.8 x 105 CFU/g, were increased at 4oC and 30oC respectively.

Regardless of storing temperature the shelf-life of Trichoderma declined gradually with increase in storage period.

The results indicated that the survival of B.

megaterium 4oC and 30oC was the same overall storage time and reach, 3.5 x 105, 2.8 x105 CFU//g under 4oC and 30oC respectively.

Bacterial spores are dormant structures and they are not affected by the environmental conditions, there is not much variation in the survival of spores 4oC and 30oC.
