Microcapsules encapsulate ① First generation bacteria. Biological studies have shown that the efficacy of bacteria is reduced with the increase of reproduction. In order to ensure the effectiveness of pollution control, Bio-Form uses the most viable first-generation bacteria. ② Microbial strains with different degradation capabilities. According to the composition and nature of the pollutants, like the traditional Chinese medicine, the various kinds of pollution-control bacteria are used, to degrade the pollutants in a targeted manner.
