Diversity of the soil microbial community and its functional aspects in man-influenced environments
CHROŇÁKOVÁ, Alica
Diversity of the soil microbial community and its functional aspects were investigated in man-influenced environments, such as colliery spoil heaps in post mining sites and upland pasture used for outdoor cattle husbandry. The study was based on the cultivation of bacteria and streptomycetes as well as culture-independent approaches. Cultivated bacteria and streptomycetes were characterized by phenotypic and genotypic means. The culture-independent approaches were based on an analysis of environmental DNA in terms of both qualitative and quantitative parameters.

Microbial communities of 4 different stages (initial [0 years after heaping of the excavated material], early [10], middle [20] and late [42] of primary succession process were studied. They were characterized by genotyping methods: ARDRA - Amplified ribosomal DNA restriction analyses and box-PCR - genomic fingerprinting using specific primer for boxA-element. Box-PCR method was chosen for comparison of methodological approaches used for characterization of heterotrophic bacterial communities. ARDRA patterns of eubacterial communities were so complex and there weren´t shown any differences among individual communities on different stages of primary succession process. Actinomycetes communities were analyzed using two sets of primers: Actinomycetes 1. (243F-1378R, Heuer et al. 1997) and Actinomycetes 2. (243F-A3R; Monciardini et al. 2002). Fingerprints, which were obtained using both of actinomycetes specific primers, showed differences between communities on the early and later stages of primary succession process. Boy-PCR analysis is still in data processing and will be published later
