[Resistance of yeast cells to plastics and elastics]. / Beitrag zur Verträglichkeitsprüfung von Gegenständen aus Plasten und Elasten unter Verwendung von Hefezellen.

For the investigation of plastics and elastics several sensitive biological methods are in use. In the Pharmacopeia of GDR, 2nd edition, a safety-test on isolated frogheart is prescribed for plastics and a safety-test on daphnia magna for elastics. Ionescu-Stoian had recommended a test using saccharomyces cerevisiae. We found a good conformity of the result given by this test with the results of the daphnia-test. On the other hand, the saccharomyces cerevisiae-test is much more sensitive than the test with isolated frogheart.
