The antibiotic lincomycin an anthropogenic pollutant –may change the bacterial diversity and resistance of soil communities by increasing selection pressure in favour of resistant phenotypes. In a laboratory experiment, two forest soils of contrasting characteristics in both pH and clay content were examined for changes in their bacterial communities after lincomycin treatment. The two soils were incubated in beakers and treated with three dosages of lincomycin. Changes in bacterial community were assessed by (i) cultivation of bacteria on two different media, and percentage of resistant colonies at two lincomycin concentrations;(ii) analysis of putative actinomycete isolates for antibiotic activities and resistance; (iii) TRFLP diversity profiles of the 16S rDNA and homologues of the resistance gene lmrB; and (iv) cloning-sequencing of PCR amplicons of both 16S rDNA and lmrB homologues
Antropogenní polutant antibiotikum linkomycin může měnit bakteriální diversitu a rezistenci půdních společenstev zvýšením selekčního tlaku ve prospěch rezistentních fenotypů. Dvě lesní půdy s kontrastujícími pH a obsahem jílu byly testovány na změny v bakterialních komunitách po opracování linkomycinem
