ATP or Adenosine Triphosphate, is an energy carrier located within living biological cells that manages all biological functions, such as food consumption, maintenance, and reproduction. It is a molecule so central to microbial life that its measurement is directly related to biomass energy level.
Without ATP there would be no life. ATP is found in any living life form, from a simple one–celled organism to you and I. If there are microorganisms present, there is ATP.
Within a fuel sample containing microorganisms, there are two types of ATP:
• Intra-cellular ATP – ATP contained within living biological cells. This is also known as Cellular ATP (cATP).
• Extra-cellular ATP – ATP located outside of biological cells that has been released from dead or stressed organisms. This is known as Free ATP (fATP).
Accurate measurement of these two types of ATP is critical to utilizing ATP-based measurements. The LuminUltra QGO-M test kit is able to distinguish between the two. This is especially relevant to managing microbial contamination in fuels because eliminating or suppressing cATP, or releasing cATP into harmless fATP, is the objective of a successful anti-contamination regime.
