Abstract Two tests for biodegradability, the modified OECD test and the modified Sturm test, were compared by application to 5 organic compounds (aniline, monoethanolamine, pentaerythritol, 1,6-dihydroxyhexane, and 2,4,6-trichlorophenol), using activated sludge from a full scale sewage works as inoculum. In both tests, there was 70 per cent reduction in dissolved organic carbon for all the test compounds. In the modified Sturm test, however, when biodegradability was assessed on the bases of carbon dioxide production, it appeared to be much lower. The discrepancy between the results was attributed to carbon assimilation and was most obvious when a preconditioned innoculum was used. The implication for standardization of tests on biodegradability are indicated.
