Test condition: Established cultures of Pseudomonas putida were incubated<br />

with various concentrations of benzene in a total volume of<br />

100 ml in 300 ml Erlenmeyer flasks with cotton lined plastic<br />

cups for 16 h at 25 degree C.<br />

The number of cells, which served as a measure to determine<br />

cell multiplication inhibition, was determined<br />

turbidimetrically.<br />

No analytical monitoring of the actual benzene<br />

concentrations was performed.<br />

Test substance: Purity: no data<br />

Reliability: (2) valid with restrictions<br />
