摘要：Acidithiobacillus thiooxidans has been confirmed to promote for a fast microbial induced corrosion (MIC) on a surface of a metal coupon in 7 days of incubation with oxygen reliable in the peptone medium. This research is conducted to clarify the mutual interactions between biofilm and the metal substratum and to further the study on the direction of biofilm influence on the metal as into a corrosion inhibition. The use of symbiont biofilm between Actinomycete and Pseudomonas aeruginosa has been proved to inhibit the MIC process as early as the third day through growth performance of the biofilm formation. We have studied the impeding process using the mediated interactions and have reported that Acidithiobacillus thiooxidans cells are smaller and thicker apart from its slower growth due to the formation of the biofilm of the microbial cell consortia. All the 3 species have significantly shared the environment, using the peptone in the medium and did not cause any pit formation or started any corrosion sign on the metal surfaces, suggesting that the great tolerance between the species has achieved the aim to reduce bio-corrosion using biofilm consortia. This evidence proved that MIC can be eradicated using other microbes or microbial interaction at the beginning of colonization.
