The products of magnetically immobilized cells. The experiments were carried out in the 50-mL centrifuge tube containing 10 mL of 0.9% NaCl at 30 °C on a reciprocal shaker at 200 rpm. NaHS was added to 2 mM to initiate the reaction in each cycle and the products were detected at the end of each cycle. a G. oxydans 621H magnetically immobilized cells; b P. putida S16 magnetically immobilized cells. Averages (n ≥ 3) with standard deviations (error bar) were shown
