A library of fifteen commercially purchased and synthetic fluorogenic probes was employed for the investigation of biomass degradation using extracts of white-rot fungi. These probes were selected or designed to mimic the dominant linkages in celluloses, hemicelluloses, and lignin, the three most abundant polymers found in biomass. The results show that white-rot fungi display a high preference for cleaving mannose- and glucose-based probes, which mimic hemicelluloses. Low degrees of cleavages were noted for xylose- and cellobiose-based probes. No cleavages were observed for probes that mimic the linkages in lignin. Overall, these discoveries prove that it is possible to employ fungi for selective degradation or release of hemicelluloses from biomass.

This report described that a hapten of racemic phosphonate 3 designed as the mimic of the transition state of hydrolysis of naproxen ethyl ester was successfully synthesized from easily available 2-acetyl-6-methoxy-naphthalene 5. Then BALB/C mice were immunized and one of the monoclonal catalytic antibodies, N116-27, which enantioselectively accelerated the hydrolysis of the R-(-)-naproxen ethyl ester was given. The Michaelis-Menton parameter for the catalyzed reaction was KM=6.67 mM and kcat/kuncat=5.8×104. This enantioselective result was explained by the fact that the R-isomer of rac-hapten was more immunogenic than the S-isomer.
