The formation of spore clumps of Bacillus coagulans and Bacillus licheniformis during high-pressure carbon dioxide treatment (HCT) was investigated. As the treatment time increased, the number of spore clumps increased. After 120 min, single spore decreased to 20-35% of the population. Addition of a surfactant decreased the hydrophobicity of spore surface and increased both the number of single spores and the rate of inactivation ratio of B. coagulans and B. licheniformis spores.
