Bacillus subtilis and Bacillus licheniformis Viable Spore Concentrates are highly stable and concentrated powders on a maltodextrin carrier. These materials have an off-white to tan appearance with little to no odor. Our strains of Bacillus subtilis and Bacillus licheniformis are strong producers of bacterial protease and lipase. These materials are generally recognized as a safe animal feed ingredient. Supplementation of these products into animal feed applications may be desirable where hydrolytic enzyme activity is desired. They are also acceptable and functional for wastewater treatment applications.
