Exopolysaccharides from Lactic acid Bacteria as Corrosion Inhibitors
Bacterial EPSs (exopolysaccharides) are believed to play an important role in the environment by promoting survival strategies such as bacterial attachment to surfaces and nutrient trapping, which facilitate processes of biofilm formation and development. These microbial biofilms have been implicated in corrosion of metals, bacterial attachment to prosthetic devices, fouling of heat exchange su...
متن کاملEffect of Sulphate reducing bacterial-biofilm isolated from refinery cooling water system and sonication on corrosion of carbon steel
Biofilm formation is one of the major problems of recirculating cooling water systems which detriments the life of equipment, through biocorrosion or microbiologically influenced corrosion (MIC). Sulfate reducing bacteria (SRB) are considered to be the major bacterial group involved in MIC. In the present study, SRB cultures are isolated from aeration basin inlet water sample of cooling water s...
متن کاملBacillus sp. Acting as Dual Role for Corrosion Induction and Corrosion Inhibition with Carbon Steel (CS)
Present work investigated the role of five different bacteria species as a corrosion inducer as well as corrosion inhibitor with carbon steel (CS). We observed the ability of different bacteria species on the metal surface attachment, biofilm formation, and determined Peroxidase, Catalase enzyme activity in the detached biofilm from the CS surface. We found that each strain has diverse conduct ...
متن کاملBeating the bugs: Roles of microbial biofilms in corrosion
Microbiologically influenced corrosion is a complex type of environmentally assisted corrosion. Though poorly understood and challenging to ameliorate, it is increasingly appreciated that MIC accelerates failure of metal alloys, including steel pipeline. Historically, this type of material degradation process has been treated from either an electrochemical materials perspective or a microbiolog...
متن کاملAntibacterial Metals —A Viable Solution for Bacterial Attachment and Microbiologically Influenced Corrosion—
Microbiologically Influenced Corrosion (MIC), otherwise coined as biocorrosion, is the influence of microorganisms on the kinetics of corrosion processes of metals, minerals and synthetic materials caused by their adhesion and growth. A closer observation of the MIC failure case analyses of engineering components showed that MIC occurs at or near welds. Preferential bacterial attack on the aust...
