Table 1.
Ratio of zone of clearance (CZ)/size of colony (CS) and chitinase activity of Bacillus licheniformis SSCL-10 wild type, maximum CZ/CS of three mutants of UV and EMS strains were selected for chitinase production.
| S. no. | Bacterial isolate | CZ/CS (after 48 h) | Chitinase activity (units/mL−1) |
|---|---|---|---|
| 1 | Wild-type strain | 13-14 | 3.40 ± 0.31 |
| 2 | UV mutant 4 | 16-17 | 10.8 ± 0.98 |
| 3 | UV mutant 7 | 16-17 | 11.2 ± 1.14 |
| 4 | UV mutant 11 | 18-19 | 13.3 ± 1.21 |
| 5 | EMS mutant 6 | 22-23 | 18.7 ± 1.42 |
| 6 | EMS mutant 9 | 22-23 | 18.1 ± 1.30 |
| 7 | EMS mutant 13 | 24-25 | 20.2 ± 1.72 |
