Biotechnology Letters Aims and scope Submit manuscript

Abstract

Acinetobacter sp. strain W-17, immobilized on porous sintered glass completely degraded 500 mg phenol l−1 in 40 h, but free cells required 120 h for this to be achieved. Immobilized cells can be used 7 times without losing their activity.
