As a result of this study the overload by pollutants and low quality of canal water in the zone downstream of Vrbas and Srbobran towns (Serbia, Yugoslavia) has been recorded. Regarding to started work on demudification of canal bottom in the industrial zone of Vrbas town, in the course of 2000 the additional investigations of mud profile downstrean of wastewater discharge into the canal have been done. In the investigated mud samples the extremely high number of organotrophic bacteria was found (up to 1.7 x 10**10 cfu/ml), but also high number of conditionally pathogenic bacteria (opportunistic bacteria) was recorded. Also, the high number of fecal (thermo-tolerant) coliform bacteria (Escherichia coli and Klebsiella - Enterobacter - Citrobacter group of bacteria), as well as the presence of colifags was found. Such findings indicate possible bad consequences to the health of humans contacting this mud, as well as to the ground water quality, indirectly, via drainage water.

Microbiological examination have been carried within the comprehensive hydrobiological investigation of Grosnica reservoir (Serbia, Yugoslavia) during 1997 and 1998. The aim of investigation was to establish the dynamics and fluctuation of specific physiological group. Grosnica reservoir with its microbial features belongs to quality class 1st-2nd according to Kohl. The comparison of bacteria community varies during the year depending of physicochemical features of a environment and the state of other facts in biocenosis. Dominant bacteria are facultative oligotrophic. The larger number of heterotrophic bacteria is in spring time only. Phosphomineralizers and proteolytic bacteria are present in the large number at the beginning of year, amylolytic bacteria are numerable during the summer and autumn. Number of nitrogen fixing bacteria and aerobic cellulolytic bacteria are changed depending on a season, too.
