^aFilter paperase (FPase) is expressed in terms of filter paper units. One unit is the amount of enzyme in the culture filtrate releasing 1 1.1 mol of reducing sugar from filter paper per min

^bCarboxymethyl cellulase (CMCase) is expressed in terms of units. One unit is the amount of enzyme releasing 1 µmol of reducing sugar from carboxymethyl cellulose per min

^cOne unit of 13-glucosidase activity is defined as the amount of enzyme liberating 1 µmol of p-nitrophenol per min
