In a more complete way, SCRM can be defined as supply chain management in order to reduce risks which can modify or even prevent the flow of information and / or physical flows (materials, products) between the internal or external actors of the company.
Regarding these infrastructures, it is necessary to consider not only the material resources but also the associated human resources.

Bio-adsorption has advantages of wide sources and varieties of raw materials, good adsorption, simple equipment, and it is easy to be operated, which can be used to remove the environment heavy metals[6].
Aureobasidium pullulans, also known as Pullularia pullulans, is semi-fungi pullulans[7], which is a kind of multi-shaped fungi with both yeast and filamentous forms and widely exists in plant materials and soil[8,9].
Materials and methods Experimental Materials Aureobasidium pullulans: Microbial Culture Collection Centre, Guangzhou; Wastewater: 0.85g of potassium dichromate was weighed into the beaker and stirred to dissolve with a small amount of distilled water, which was then transferred into the 1000mL volumetric flask to a constant volume with distilled wate, hence the solution of Cr6 + with the concentration of 300 mg / L.
