Profiles of secreted and cellular
proteins obtained from cultures grown in the presence of HMF. Secreted (A) and cellular (B) proteins were extracted from P. ostreatus 8, 24, and 48 h after addition of 30 mM of HMF to the media. The proteins were resolved by SDS-PAGE 4% to 12%. C: control cultures without HMF, H: cultures exposed to HMF. Arrows point to major visible difference in the profiles.
