Specific and differential media for the isolation and identification of biocorrosion producing agents

MICROBIOLOGICAL COUNT VIALS

It is a process in which microorganisms accelerate corrosion reactions inside metallic systems, their evolution only requires a minimum amount of free water. The biocorrosion phenomena have not been associated to just one mechanism or attributed to a single biological agent, for that reason the detection of different population groups associated with this problematic is necessary.

Biofilm formation on the metal surface is responsible for the origin of the micro environmental conditions that causes localized metal loss. That is why the early identification of present bacterial groups related to this phenomenon is a key element for the timely implementation of monitoring activities. Continuing with the accomplishment of its mission the C.I.C. has developed BioCor, a product oriented to diagnose and monitor bacterial populations associated with corrosion processes.

WHAT IS BIOCORROSION?

Specific and differential media composed by nutritious substances oriented for the isolation and identification of the main bacterial groups associated with biocorrosion.

• Detection and quantification of the main biological agents involved in biocorroion phenomena (Sulfate-Reducing Bacteria, Thiosulfate Reducing Bacteria, Acid Producer Bacteria, Total Heterotrophic Bacteria, Total Anaerobic Bacteria, Ferro Bacteria) using solid and liquid samples from industrial systems.

• Monitoring of the effectiveness of biocide treatments (planktonic bacteria).

• Obtainment of a microbiological profile of planktonic bacterial of a system.

• Tracing sessile bacteria presence through the analysis of biocoupons.

DESCRIPTION

PURPOSES

MICROBIOLOGICAL COUNT VIALS

All BioCor culture media products composition, preparation and serve specifications follow the guidelines described in the standard NACE TM-0194(04) and ASTM D4412-84 (09)

BioCor is available in 6 formulations, in order to respond to the need of isolation of the various bacterial groups commonly associated with biocorrosion.

• It is a product easy to handle both in field and laboratory.

• It has components that allows a high rate of selection and differentiation of potential corrosive bacteria.

• Innocuous and environmentally safe. • High stability under controlled laboratory

conditions. • Nonflammable. • Thanks to its 6 formulations the common

bacteria groups associated with corrosion processes can be timely traced.
