Regulation potential of earthworms as related to diversity and functioning of soil microbial community
KOUBOVÁ, Anna
Earthworm-microbial interactions with emphasis on the passage effects of Eisenia spp. on microbial community were investigated. The study was focused on earthworm potential to regulate functional microbiota in cattle-impacted soils. Microbial communities were studied through a combination of polar lipid analyses, molecular, and culturing methods.
The structure of microbial community in pasture soil as related to animal impact - with emphasis on the group \kur{Archaea}
KOUBOVÁ, Anna
The aim of this thesis was to characterize the group of Archaea within the total microbial community in soils from three areas differently impacted by grazing cattle. The size and the structure of the archaeal community were estimated by the analysis of the cell-membrane etherlipids.
Archaea – the important part of soil microbial community
Němcová, Anna ; Elhottová, Dana
Archaea is a very old group of prokaryotic microorganisms distinguished by unique characteristics from other procaryotic representatives. Archaea represent the third discrete domain of life. The recent research focused on biology and ecology of Archaea has brought quite new and fascinating information about these microorganisms as well as about the life evolution in general. By virtue of application of recent molecular methods, it is apparent that archaeal habitat is not limited only to extreme environments but it is a distributed group coexisting with other microorganisms in common environments. The study of archaeal role in processes of C and N transformation connected with production and emission of greenhouse gases belongs to important problematic of recent soil biology. From a point of view of the evolutionary relations among soil organisms or interaction with other representatives of edafon the study of Archaea represents other important tasks of soil biology.
