Abstract��
The regulation effect of growth regulator is realized by the interaction between receptive proteins in organism.Growth regulator has been widely used in the regulation of animals and plants,but the study in microorganism is still in former stage.Solubilization is an important property of dispersion agent.Different dispersant has different way in solubilization. At present most common used dispersant in industry is mono-surfactant such as Tween80 which is limited in dispersion and solubilization.The application of multiple surfactants is worth to further discuss.
