test substance, Centralit, was tested for the ready biological
degradability in Closed Bottle Test. Based on results of this 28 days
study Centralite is not ready biodegradable.
the presence of a rich nutrient medium Centralite (diethyldiphenylurea)
was biotransformed by a consortium of microorganisms from an inoculum of
anaerobic and activated sewage sludge. The substance was susceptible
under set of conditions (aerobic/anaerobic, static culture/continuous
culture). N-ethylaniline and ethyldiphenylurea were identified as
transformation products. Centralite was
reduced under aerobic conditions to approximately 35% of initial
concentration after 5 days. These results suggest that the compound may
be successfully removed in a continuous treatment process operated in
estimates for preliminary identification of substances with a potential
model prediction (BIOWIN 2) - fast
biodegradation timeframe prediction (BIOWIN 3) - weeks - months
