Extracellular enzyme activities produced by Pseudomonas sp. during growth on different media†
| Medium‡ | Protease (U/mL) | Lipase (U/mL) | α-glucosidase§ (U/mL) | N-acetyl-β-glucosaminidase (U/mL) |
|---|---|---|---|---|
| C10B | 66.3 ± 3.0a | 0.08 ± 0.01a | 0.06 ± 0.002a | 0.02 ± 0.01a |
| C50B | 94.5 ± 4.5 b | 0.03 ± 0.003 b | 0.03 ± 0.002 b | - |
| CWPB | 161.8 ± 6.1 c | 0.37 ± 0.02 c | - | - |
| TSB | 178.5 ± 7.6 d | 0.06 ± 0.01 a | - | - |
| SMB | 67.9 ± 3.4 a | 0.31 ± 0.02 d | 0.67 ± 0.03 c | 0.01 ± 0.01 a |
Values are expressed as mean ± standard deviation of three independent experiments.
C10B: casein 10 g/L broth; C50B: casein 50 g/L broth; CWPB: cheese whey powder broth; TSB: tryptone soy broth; SMB: skim milk broth.
β-glucosidase, α-galactosidase, β-galactosidase and N-acetyl-β-galactosaminidase activities were not detected.
Data were subjected to analysis of variance and, when appropriate, to Tukey’s test to examine where the differences existed. Values were considered significantly different from each other when P<0.05.
