Microbial reaction to soil contamination with Cd(II) at different temperatures.

Author information

Department of Microbiology, University of Silesia, Katowice, Poland.


The response of the indigenous bacterial community to the addition of single doses of Cd(II) was studied in a sandy-loam soil at 6, 20 or 30 degreesC. Soil pollution significantly reduced the number of bacteria growing on 0.1% tryptic soy agar (TSA) and those growing on 0.01% TSA especially at 30 degreesC shortly after the addition of the metal. However, an increase in cfu numbers and dominance values of metal-tolerant populations were observed at this temperature with time. In addition, changes in the kinetics of colony development were found over the period of study.
