These results suggest that phenol oxidase, peroxidase, and cellobiohydrolase specific activities are more strongly related to shifts in community composition than b-glucosidase and b-xylosidase. It is also interesting that the specific activity of phosphatase was also correlated with a large number of individual fatty acids and sulphatase was not. The majority
of microbes produce phosphatase, but it is possible that only a portion of the microbial community may produce phosphatase
at any one time (Hysek and Sarapatka, 1998)
