Project Start: Limitation of Microbial Degradation of Middle Distillates

Due to the development in the field of alternative fuels such as esterified vegetable oils and increasingly from de-fossilised, paraffinic products such as hydrogenated vegetable oils (HVO) or synthetic fuels (XtL) to oxygenates to mineral oil-based products, there are significant changes with regard to composition and product properties. In the future, it can be expected that the diversification and flexibilisation of energy sources to ensure security of supply, will lead to an increase in the material flows from synthesis processes for the production of paraffinic energy sources.

The resulting increasingly heterogeneous composition changes and determines the "millieu" for possible bacterial growth. Against this background, the influence of alternative fuels on microbiological activity has not yet been sufficiently systematically investigated.

Within the DGMK projects 715 and 770 the identification of microorganisms in storage tanks, the definition of growth-relevant parameters and the influence of microbes on materials and middle distillates were in the foreground.

In the DGMK project 823 "Limitation of microbial degradation of middle distillates" started on 01.11.2019, the focus is on the composition of liquid energy sources and the following points are clarified:

  • Assessment of chemical and physical properties as well as metabolic activity in relation to the nutrient supply
  • Influence of the fluid composition on the inhibition of biofilm formation or microbial growth.
  • Development of potential avoidance strategies to minimize microbial growth or biofilm formation and a test method for the timely assessment of microbial susceptibility
