Abstract
Abstract The environment of industrial cities is usually exposed to extreme impacts of anthropogenic contamination originating from fossil fuel combustion, road traffic, industry, ore mining and dressing. The degradation potential of contaminated soils greatly depends on the diversity and function of the microbial ecosystem in the given locality; in individual communities, it is possible to diagnose identical as well as different characteristics of specific bacterial strains. From the real soil samples within the City of Ostrava, namely localities strained by industrial activities, new strains were isolated and compared on the grounds of biochemical identification results using a modern system of BIOLOG MicroStation. Basic characteristics of the new isolated strains are stated, which document their phenotypic diversity not only on the level of the Pseudomonas genus but also on the level of the individual species. The differences in the physiological parameters of isolated strains are attributed to the capacities of the soil microorganisms to adapt to the polluted environment conditions. The paper offers an overview of the significance of phenotypic characterization for identification of microorganisms and their correct taxonomic classification.
