Oral:

Many enzymes utilize divalent metal ions as co-factors for catalysis. In this work was studied the effect of metal ions on activity and stability of crude extracts containing cellulases, obtained from submerged cultures of Bacillus sp. SMIA-2 containing corn steep liquor, sugarcane bagasse and passion fruit rind flour. The activit of avicelase (avicelhydrolyzing enzymes) was stimulated by Co2+ and Ba+2 at 1mM concentrations, while the CMCase (carboxymethylcellulose-hydrolyzing enzymes) was stimulated mainly by Mn2+ , indicating that these ions had a functional role in the molecular structure of the cellulases of Bacillus sp SMIA-2.
