The following bacterial genera were identified in sediment samples from the Uh and Latorica rivers: Citrobacter, Proteus, Pseudomonas, Escherichia, Enterobacter, Enterococcus, Staphylococcus and Salmonella. Both rivers are frequently polluted by crude oil substances and by municipal waste waters. The growth development of bacteria in collected samples and samples inoculated by standard strains of Escherichia coli 324/70 and Pseudomonas aeruginosa Ps 168/79 was followed. Over a one year period, from September 1994 to September 1995, a high degradation of crude oil substances ranging from 65.5 percent to 96.1 percent was observed. The results indicate an important role of both natural as well as other conditions in biodegradation processes. The presence of suspended soil particles and suspended municipal wastewater particles is also important in the water environment as they form suitable conditions for growth development of microorganisms
