Název v původním jazyce

Growth rate of bacteria is affected by soil texture and extraction procedure.

Popis výsledku v původním jazyce

Effects of soil texture on the extraction efficiency of bacteria from soils and on biosynthetic activity of the extracted bacteria were studied. Bacteria extracts were prepared from three soils of different texture by homogenization (ultrasonication andmixing) or by homogenization-centrifugation at different speeds. Bacterial biosynthetic activity was estimated using thymidine and leucine incorporation techniques. In each step of the extraction procedure, a higher extractability of bacteria was obtained in finer soils than in coarse soil. Also cell-specific growth rates of bacteria were higher in the finer soils than in the coarse soil. However, in all soils, the extracted bacteria always had significantly lower cell-specific thymidine and leucine incorporation rates than the bacteria in soil slurries and thus did not represent so well the bacterial growth in the original soils. The total declines in cell-specific incorporation rates caused by the extraction were larger in fine soil (
