The specific activity of b-glucosidase and b-xylosidase were correlated with monounsaturated fatty acids, typical of
Gram-negative bacteria. These enzymes release simple sugars, and Gram-negative bacteria are often fast growers,
which compete for simple substrates (Atlas and Bartha,1993). In contrast, cellobiohydrolase, phenol oxidase, and
peroxidase were correlated with fatty acids typical of Grampositive and Gram-negative bacteria, fungi and the actinomycetes.
