TABLE 1.
Culture | Cu concn (μM) | A600 | Cu-complexing capacity (μmol of copper · g of CDW−1)a |
---|---|---|---|
RTR | 0.25 | 2.87 | 1.85 |
5 | 2.90 | 0.20 | |
PP358 | 0.25 | 2.76 | 2.07 |
5 | 1.69 | 2.55 |
One A600 unit corresponds to 0.43 g of CDW/liter (7). POI mass was obtained by measuring the POI area and converting it by using the following conversion factor: 0.137 μM CBL per HPLC POI area unit (see text).
