The external appearance of microorganism used to bioleaching copper from waste printed circuit boards under SEM
The microorganism like Acidithiobacillus ferrooxidans can be used to leach the copper out of waste printed circuit boards. And the leaching effect is very good. The microorganism external appearance is hard to check up because they are too small to be clearly observed under optical microscope. If the scanning electrical microscope to be used, it need special process to pre-treat it and covered by gold or carbon before the scanning. Using this pre-treat process make the microorganism became hard and not showing the original morphology of the microbe. This paper provides a new method to observe the microbe under scanning electric microscope without pre-treat and got the nature microbe picture. Different types of microorganisms pictures are provided. The EDX analysis of microbe shows the main elements composition. This method can be widely used in the bioleaching and other related industries to determine the external appearance of microorganisms.
