the growth curve model of psb

The pollution of heavy metals in soil is a major problem of environmental sanitation in the world.The governance process faces many difficulties. Phytoremediation is a promising technology because it does not cause secondary pollution and low cost. However, the growth process of these plants are typically inhibited by high concentrations of heavy metals, It causes slow growth of plants and decelerates the phytoextraction process. Therefore, our team engineer a class of phosphate-solubilizing bacteria(psb) to reduce the concentration of heavy metal ions in the soil. It also accelerates the growth of plants and repairs soil. Faced with severe heavy metal pollution, the environment of soil is complex and diverse.

Be familiar with the growth condition of the psb.It becomes very important.In order to better understand the growth condition of phosphate-solubilizing bacteria(psb), we adopted the classic Gompertz model.The following is the fitting effect diagram of growth curve
