Fig. 5From: Degradation of chlorotoluenes and chlorobenzenes by the dual-species biofilm of Comamonas testosteroni strain KT5 and Bacillus subtilis strain DKTCell numbers in single-species biofilms (filled squares) of B. subtilis DKT and monochlorobenzene degradation (filled diamonds) by the bacterial strain. The experiments were carried out using MMY medium supplemented with 1.0Â mM 2-chlorotoluene (a) and without 2-chlorotoluene (b)Back to article page
