Detection of microorganisms in the soil using CARD-FISH (Catalyzed Reporter Deposition - Fluorescence in situ hybridization)
Krištůfek, Václav ; Kasalický, Vojtěch ; Chroňáková, Alica ; Elhottová, Dana ; Němec, Jan
CARD-FISH protocol (Catalyzed Reporter Deposition - Fluorescence in situ Hybridization) for detection of soil microbial community composition was successfully established in the Institute of Soil Biology. CARD-FISH is the relatively new molecular biology tool permitting to quantify distinct groups of microorganisms by hybridization of specific oligonucleotide probes. Compared to classic FISH-protocol the probe-attached enzyme amplifies the fluorescent signal and enables to detect nearly all microorganisms in soil or in organic compounds. As the first, we used this method to determine the bacterial community composition of a dated layer of guano-heap from Domica Cave (Slovak Carst National Park, Slovakia). We quantified the percentuel composition of Archaea, Eubacteria (.i.Planktomycetales, Verrucomicrobiales./i. included) and major bacterial groups (Actinobacteria, proteobacteria, .i.Cytophaga-Flavobacter./i.-Bacteroidetes, Sphingobacteria).
Measurement of coke porosity by image analysis methods
Ščučka, Jiří ; Kožušníková, Alena
An effective method for visualization and quantitative analysis of coke porosity is presented in the paper. The method is based on image processing and analysis combined with fluorescence microscopy of impregnated coloured preparations and enables the determination of percentage portion of pores in the coke, mean pore-size, mean cell-wall thickness and their distribution.
