3.2.1.91 additional information manno-oligosaccharides, MOS, are competitive inhibitors ofthe CBHI. The negative effects of mannan and manno-oligosaccharides (MOS) on the hydrolytic action of cellulases indicates that the inhibitory effect is at least partly attributed to the inhibition of Ta Cel7A (CBHI), but not on beta-glucosidase Thermoascus aurantiacus
