TABLE 1.
Enzymatic activities of the culture supernatants of Pseudoalteromonas sp. strain A28 and two mutants lacking algicidal activity
| Strain | Enzymatic activity (U ml of supernatant−1)
|
|
|---|---|---|
| Proteasea | DNaseb | |
| A28 | 8.2 | 9.4 |
| NH1 | 0.9 | 8.8 |
| NH2 | 1.1 | 9.0 |
a
Protease activity was measured by using azocasein as a substrate. One unit of protease activity was defined as the amount of enzyme that caused an incremental change of one absorbance unit per hour.
b
One unit of DNase activity was defined as the amount of enzyme depolymerizing 1 μg of DNA per min at 30°C.
