Microbiological properties of deposol in the location of Banatsko Karadjordjevo

Abstract

Disposal of drilling mud is a considerable problem in the process of crude oil pumping and transportation. Microorganisms are the most important component of the soil biological phase as their enzymatic systems take part in degradation and synthesis of soil compounds. Soil samples were taken from the location of Banatsko Karadjordjevo. The results show high values of total numbers of microorganisms and azotobacters in indigenous soil than in deposol. The numbers of ammonifiers, oligonitrophiles, actinomycetes and fungi were higher in deposols than in the local soil. The density of the studied groups of microorganisms and DHA decreased with depth, with the exception of actinomycetes.
