AI Technical Summary
Technical Problem
Existing processes for preparing oil dispersions with living microbial cells are unstable and can disrupt the cells due to high shear mixing, leading to poor stability and inactivation.
Method used
A process involving mixing hectorite and oil at low shear forces (0.1 to 20 kW/m³) to form a gel, followed by incorporating microbial cells, with optional activators like quaternary ammonium salts, to create a stable oil dispersion.
Benefits of technology
The resulting oil dispersion maintains microbial cell viability for extended periods, with stability up to 2 years at 25°C, and exhibits rheological properties suitable for agricultural applications.
