Later AB0, taxonomically named as Amycolatopsis tucumanensis
DSM 45259 (Albarracín et al., 2010a), showed a growth inhibition
of 32% in batch culture during 6 days of incubation in the presence
of 39 mg l1 Cu. Measurement of residual Cu indicated a useful
reduction of 71.2% at this time (Albarracín et al., 2005). Subcellular
fractioning assays also showed that 40% of the retained Cu was
associated with a produced exopolymer (Albarracín, 2007) (Fig. 3)
