Atrazine, a persistent and widely-used herbicide can be degraded by Pseudomonas sp. strain ADP. There is need for a room temperature stable formulation that might help to improve infield delivery and performance. Water activity throughout the study period remained constant (~1.0 aᴡ) for all test samples. Immobilization of Pseudomonas sp. strain ADP onto zeolite using a xanthan gel maintained survival for at least 10 weeks at 25 ℃. Approximately 1 log loss by week 7 was observed when xanthan gel was not used. Pre-wetting the zeolite increased the time to 1 log loss to 9 weeks. Formulation, and to some extent moisture does influence the stability of Pseudomonas sp. strain ADP immobilized onto zeolite.
