Table 2. Substrate specificity of chitinase from Paenibacillus chitinolyticus strain UMBR 0002.
| Substrate | Specific activitya (mU mg−1) | Relative activitya,b (%) |
|---|---|---|
| Colloidal chitin | 567.20 ± 34.48 | 100 ± 6.08 |
| Chitin powder | 288.69 ± 17.22 | 50.90 ± 3.04 |
| Chitosan oligosaccharide | 0 | 0 |
| Carboxymethyl chitosan | 0 | 0 |
| CMC-Na | 0 | 0 |
Notes:
a
Experiments were conducted three times and standard errors are reported.
b
Relative enzyme activity calculation using colloidal chitin as the reference value (100%). Abbreviations: CMC-Na, carboxymethyl cellulose sodium salt.
