L51963 Environmental Benign Mitigation of Microbiologically Influenced Corrosion (MIC)

Corrosion, microbially influenced

The objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) on the internal surfaces of metallic natural gas pipelines. The goal is one or more products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this year has been to evaluate a number of methods to fractionate and concentrate the components found in the pepper extracts. The separation methods considered include size exclusion chromatography, hygroscopic and hydrophobic extraction with HPLC fractionation and analysis

preparative HPLC

and other methods based on the chemical class of compounds to be evaluated. The first classes to be studied are: terpenoids

phenolics

fatty metabolites

alkaloids

and other products of secondary metabolism in plants. Other methods to be reviewed as needed include: planar chromatography

supercritical water and CO2 extraction

and ion-exchange methods. A review of the patent literature and scientific databases found no evidence that any of the potential products have been patented, indicating potential for establishment of a strong intellectual property position. The work plan for the continuation of specific tasks of this project for two additional years was completed and accepted for funding. Laboratory testing protocols for control of biofilm formation and/or biocidal activities for both aerobic and anaerobic microorganisms known to support MIC were codified.
