Abstract
Methods for spray drying gram negative bacteria are provided. Such spray drying methods are performed under conditions that allow for the spray dried composition to retain the biological activity of interest of the gram-negative bacteria. Further provided are compositions comprising a spray dried gram-negative bacteria, where the spray dried formulation comprises at least 105 CFU/gram of said gram-negative bacteria. The gram-negative bacteria employed in the various methods and compositions can comprise a biological activity of interest which, in specific embodiments, controls one or more pathogens that cause plant disease and/or improve at least one agronomic trait of interest. The spray dried formulation can be used as an inoculant for plants. Methods for growing a plant susceptible to plant disease and methods and compositions for controlling plant disease are also provided. Further provided are methods and compositions of increasing disease resistance in plants. Methods and compositions for improving plant health and/or improving at least one agronomic trait of interest are also provided.
