Fig. 5From: Microbial responses to transient shock loads of quaternary ammonium compounds with different length of alkyl chain in a membrane bioreactorA schematic representation of the acute toxicity induced by the transient shock loads of different kinds of QACs. The dash lines in plasma membranes indicate that AMO, NOR, NAR and NIR might be assigned to different phylotypes. The gradually lightened color of AMO, NOR, NAR, NIR, dehydrogenase, and CAT in the three panels indicates an increased negative influence. The line thickness of the arrows associated with ATP and H2O2 (transformed to either H2O or â‹…OH) is proportional to their quantityBack to article page
