Utilization of coal mine solid waste by phosphate-solubilizing bacteria and its application in reclamation
Coal is the major energy in China,coal gangue and Fly Ash (FA) are two major solid wastes generated from coal-mining which brought about not only the problem of plenty of land occupation,air,water,soil environment and heavy pollution,but also made a lot of resources for the longterm completely exposed to the atmosphere waste.Coal gangue and FA containing phosphorus (P) are an essential macronutrient for plant growth and development,if these resources can be recycled,it will reduce environmental pollution effectively,promote the agricultural production and ecological restoration in mining areas.The Phosphate-Solubilizing Bacteria (PSB) are a rhizospheric microorganism which solubilizes the insoluble P to soluble forms of P for plant growth and yield,With the rapid development of modern biotechnology,PSB is more and more widely used in agricultural production and the environmental protection areas.This paper introduced the harmfullness of coal mine solid waste in China,summarized the mechanism of solubling P,utilization of coal mine solid waste by PSB,application in ecological restoration with PSB and the application prospect.
