Resumo: |
Endoglucanase and exocellobiohydrolase produced b Lentinula edodes (Berk.) Pegl. strain thatt was cultivated in carboxymetilcellulose (CMC) or microcrystalline cellulose (Avicel) liquid media. The concentration and type of cellulose influenced the enzyme activity and production. Extra-cellular cellobiase activity was not detected in CMC or Avicel media. This enzyme was detected in mycelial extracts only. With 1.7% Avicel liquid medium, the strain did not produce exocellobiohydrolase, but 74 µmol RBBR/mg protein/min was detected with 0.5% Avicel. The substitution of Avicel by 0.5% CMC reduced this activity. Endoglucanase also had maximum activity in 0.5% Avicel medium (approximately 820 UI/mg protein) after 96 h incubation. In supernatants from 0.5% CMC, the maximum activity attained was 200 UI/mg protein only.
