Table 1. Glycoside hydrolase activities produced by the thermophilic community.

Enzyme	Activity (U/ml)	STDEV
Endoglucanase	0.466	0.015
Cellobiohydrolase	0.014	0.001
β-D-glucosidase	0.041	0.001
Endoxylanase	1.319	0.013
α-L-arabinofuranosidase	0.210	0.010
β-D-xylosidase	0.018	0.001

Endoglucanase and endoxylanase activities were determined using the DNS assay on carboxymethyl cellulose or birtchwood xylan. Other activities were assessed using p-nitrophenyl substrates. U = µmol/min and is reported as the mean and standard deviation of triplicate experiments.
