摘要：

Bacteria producing acid from maltose, cellobiose, arabinose or xylose and bacteria hydrolysing starch, pectin, xylan or cellulose decreased 8- to 11-fold due to the soil contamination. Chitin hydrolysers were 5 times less abundant at the most polluted site compared with background levels. Soil respiration rate and urease activity decreased by about a factor of 4, but phosphatase activity and mycelial lengths were unaffected by the soil contamination. Soil bacteria showed a sigmoidal response to the log of metal concentration in the soil and were affected at a lower pollution level than the other biological variables in the study. A multivariate analysis (partial least squares) showed that soil metal contamination and soil pH were the two environmental factors influencing the soil microorganisms.
