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