TEST ORGANISM
- Common name: Duckweed
- Strain: G3
- Source (laboratory, culture collection): In-house culture kept under axenic conditions; preculture was prepared at least 7 days before the tests; healthy colonies with 3-4 fronds. Originally, the culture was obtained from Friedrich Schiller Universität, Institut für Allgemeine Botanik und Pflanzenphysiologie, Jena, Germany.
- Preculture: 7 - 10 days (7 days in this study) before testing, sufficient colonies are transferred from the stock culture aseptically into fresh sterile medium and cultured under the conditions of the test prior to beginning the test.
Water media type:
freshwater
Limit test:
yes
