Microbial corrosion is an electrochemical process that microorganisms able to start, facilitate or accelerate corrosion reaction, without changing electrochemical nature of it. One of the ways convincing for existence microbiological corrosion against chemical corrosion, identifying microorganisms that are involved in this type of corrosion. Iron bacteria, Sulfur bacteria and Sulphate-Reducing bacteria are the important microorganisms in the corrosion. Because of the most industries are a water-related, the various departments are involved in the growth and microbial activity. And annual imposes heavy costs to the industry in worldwide. Hence, various methods have been proposed to deal with this phenomenon including cathode protection, inhibitors, coatings containing chemicals and self-healing,s organic materials, biocide, biofilms, polysaccharides produced by microbial species and the role of nanotechnology in corrosion control. In this paper, we introduce microbial corrosion and new methods of protection corrosion such as using of biofilmss and microbial polysaccharides that are both economical and biodegradable because of they are produced from biological sources.
