The growth inhibition test with Pseudomonas putida was conducted, and a toxicity control in the CBT and the ZWT was used. The colony-forming units were monitored in the CBT; the test results for the biodegradability after 28 days were: 30% for vincristine, 20% for vindesine, and 10% for vinblastine. Therefore, none of the test compounds met the criteria for being readily biodegradable (> or = 60%). Vinblastine was biodegraded up to 18% in the ZWT after 40 days, and therefore, not inherently. Toxicity towards wastewater bacteria was not found.",
