“…Due to the irregular sampling intervals and small number of observations it was not possible apply time series analysis in data analysis. Multivariate statistics, primarily factor analysis and principal component analysis are a valuable tools in the study of population shifts in freshwater river bacteria [6]. Multivariate statistics allow to detect patterns in and to reduce the dimensionality of complex multivariate data.…”

Numbers of different bacterial groups and physico-chemical water quality parameters were studied during four year period in two rivers receiving mine water from underground oil shale mine. Input of mine water causes increase of alkalinity, sulfate and calcium ion concentration in river water. Bacterial community structure of studied rivers was altered by mine water and had clear seasonal pattern. The results indicate that input of mine water increases number of viable heterotrophs and lipolytic bacteria in river water, especially during underground oil shale burning.

Studies on aquatic ecosystems at the trophic level of bacteria include population succession and the movement of species through the water column. Factor and path analysis of environmental parameters and the bacterial profiles indicate that the bacterial populations are under the control of environmental factors. The most important environmental factors in the Canadian study reported here are temperature followed by oxygen levels, nutrient levels, and ion concentrations. A major revolution in investigative approaches has begun in aquatic bacterial population studies using technology based on molecular methods. Finger print analysis of bacterial 16S RNA (molecular phylogeny) has not only changed the classification of bacteria but also the approach to solving environmental problems. The bacterial groups have been placed into species that are more functionally and ecologically aligned. Uncultured mixed biomass can be examined by gene probes for both procaryotes and eucaryotes to identify specific nucleotide sequences. Aquatic ecosystem health is maintained by the balanced biota and the process of biodegradation is an important stage in bioremediation. Control of toxic wastes in the waters and groundwaters can be accomplished by in situ bioremediation using indigenous microorganisms as demonstrated by the field study reported by Litchfield et al. (1990).
