In this article, the problem of microbial contamination occurring in the fuels and oils was presented. It shows the types of microorganisms and the conditions for their growth. Then the factors influencing the growth of bacteria in petroleum products were described in detail. In the next section the symptoms, development and contamination of petroleum products was discussed. The influence of microbial contamination on the marine engine fuel system and the problems that this brings were also presented. In the following part of the article, the impact of microbial contamination of fuel tanks and purifiers was described. Then the causes of sludge were discussed and contamination layers in the settling tanks were presented. In the next part of the article the fuel impact modelling of microbial contamination on filtration efficiency was performed. The modelling presented in the article is an example showing how undesirable phenomenon is the microbial contamination and how pollution affects the other elements of the entire system. As part of the modelling, numerical model of filtration with the solution was presented. Then analysis results on the basis of the impurities concentration characteristics in the fuel as a function of the fouling thickness in the partition of the filter is performed. The development of impurities was divided into three stages. For each case the line trend and forecast further growth after the application of measures to prevent the proliferation of microorganisms were designated. The article was completed applications, of which the most important is the need to combat harmful microorganisms. And besides, there is a need to find new methods of combating microbial contamination that will not destroy beneficial microorganisms and will be environmentally friendly.
