TABLE 1.

Copper-complexing capacities of accumulated CBL in growth media derived from Methylosinus trichosporium OB3b (=RTR) and PP358

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
a

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).
