Abstract
A rapid and inexpensive test has been developed to investigate the inf luence of elevated heavy metal concentrations on the degradation of bi odegradable plastics. Using an overlay agar technique it could be demo nstrated that copper concentrations above 8 to 14 mg/L inhibit the deg radation of powdered poly(3-hydroxybutyrate), (PHB), by Acidovorax del afieldii. This is the first study demonstrating the inhibiting influen ce of metals on the biodegradation of PHB.
