WHAT IS THE MICROBMONITOR®2 TEST?
MicrobMonitor2 is a simple and easy to use test kit which enables the quantitative assessment of the viable microbial
content in petroleum products including liquid fuels, oils and associated water. MicrobMonitor2 enables on-site or
laboratory testing in accordance with ASTM and IP Standard Methods ASTM D7978 and IP613 - Determination of the viable
aerobic microbial content of fuels and associated water - Thixotropic Gel Culture Method. MicrobMonitor2 is
recommended in the IATA Guidance Material on Microbiological Contamination in Aircraft Fuel Tanks for monitoring
microbial contamination in aircraft fuel tanks and is listed in the Aircraft Maintenance Manuals of Airbus, Boeing, BAE
Systems and other leading aircraft manufacturers. The test is used by a wide range of military services for monitoring
contamination in aviation, marine and ground fuels and is NATO Codified (6640-99-834-3573).
MicrobMonitor2 provides a total count of microbial colony forming units (CFU). CFUs are the conventional unit of measure
for microbial contamination used in a wide range of industries. MicrobMonitor2 detects the important bacteria, yeasts and
moulds which can contaminate petroleum products including Hormoconis resinae, Aspergillus, Candida and Pseudomonas
The MicrobMonitor2 test consists of a screw-capped bottle containing a thixotropic nutrient gel. A sample is added to the gel
using a sterile plastic loop or syringe (provided). The bottle is shaken and the gel liquefies and the sample, and any
microorganisms in it are dispersed. The gel is re-set into a flat layer and the bottle is incubated in the dark. The gel
contains components which sustain the growth of viable microorganisms and the sample itself contributes additional
nutrients. Viable microorganisms in the sample grow into visible spots known as “colonies”, and a reactive compound
changes the colour of these colonies to red or purple so that they can be easily seen.
MicrobMonitor2 includes 50 tests, containing everything that is required to perform the test:
50 MicrobMonitor2 test bottles
50 Sterile syringes*
50 Sterile loop dispensers*
50 Bottle labels
MicrobMonitor2 has been developed and patented by ECHA Microbiology Ltd. and it is marketed worldwide by
