The effects of heavy-metal-containing sewage sludge on the soil microbial community were studied in two agricultural soils different textures, which had been contaminated separately with three predominantly single metals (Cu, Zn, and Ni) at levels more than 20 years ago. We compared community-based microbiological measurements, namely, phospholipid fatty acid (PLFA) analysis to reveal changes species composition, Biolog system indicate metabolic fingerprints communities, thymidine...
The development of metal tolerance in soil bacterial communities exposed to different heavy metals was examined under laboratory conditions. An agricultural amended with Zn concentrations studied most intensively, and measurements were made over a 28-month incubation period by means the thymidine incorporation technique. Tolerance levels not affected lower than 2 mmol kg (dry weight) soil(sup-1), but above this value, level increased exponentially logarithm concentration. detected after only...
A thymidine incorporation technique was used to determine the tolerance of a soil bacterial community Cu, Cd, Zn, Ni, and Pb. An agricultural artificially contaminated in our laboratory with individual metals at three different concentrations, results were compared obtained by using plate count technique. Thymidine found be simple rapid method for measuring tolerance. Data this very reproducible. linear relationship between changes levels techniques ( r = 0.732, P < 0.001). increase metal...
The ecosystem response to fire is often linked severity and recurrence, with potentially large consequences on both aboveground below–ground processes. Understanding the impact has become increasingly important in light of recent changes disturbance regimes due climate change. Although impacts above vegetation below soil physical chemical properties are well documented, it remains unclear how affects fine-scale microorganisms. Microbial communities responsible for driving essential processes...
The presence of emerging pollutants, and specifically antibiotics, in agricultural soils has increased notably recent decades, causing growing concern as regards potential environmental health issues. With this mind, the current study focuses on evaluating toxicity exerted by three antibiotics (amoxicillin, trimethoprim, ciprofloxacin) growth soil bacterial communities, when these pollutants are present at different doses, considered short, medium, long terms (1, 8 42 days incubation)....
Microbial community DNA was extracted directly from an arable soil experimentally polluted with Cd, Cu, Ni, Pb or Zn, and incubated for 34 months. Broad-scale measurements of changes in microbial structure were assessed by applying %G+C profiling hybridisation techniques to the DNA, compared phospholipid fatty acid (PLFA) profiles. profiles, statistically using parameterisation principal component analysis, differed between treatments. Community revealed a range similarities The combination...
ABSTRACT The immediate effect of low and high severity wildfires on the main soil properties, as well their short‐ medium‐term evolution under field conditions, was examined. study performed with three pine forest soils (two Leptosols one Humic Cambisol, developed over granite basic schist, respectively), located in Atlantic humid temperate zone (Galicia, NW Spain). Samples were collected from A‐horizon (0–5 cm depth) burnt corresponding unburnt soils, immediately 3, 6 12 months after...
