Constituent 1
Study design
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- other: soil microflora of Niagara silt loam
- Details on inoculum:
- 1 ml of a 1% suspension of Niagara silt loam
Initial test substance concentration
- Initial conc.:
- 25 mg/L
- Based on:
- test mat.
- Details on study design:
- - Nutrient solution contained inorganic nutrients and test substance as the
sole carbon source.
- 1 ml of a 1 % suspension of Niagara silt loam was added to closed bottle
containing 40 ml of nutrient solution.
- Bottles were incubated in the dark at 25 °C.
- Contact time was up to 64 days including adaptation period.
- Ring cleavage was checked by decrease of absorbance at 265 nm,
measured after centrifugation in the supernantant. Precipitates and
supernatants were returned to the appropriate reaction bottles.
- Control tests were performed with identical samples except that 8 mg of
HgCl2 and 5E-07 M Tween 80 were added to each bottle.
- Tests for toxicity of the test substances to microorganisms were done on
identical samples however using glucose as an additional source of
carbon.
