“…Combination results from three groups and a method for producing high starch duckweed 3.5.1. Growth rate Duckweed relies mainly on vegetative reproduction (Lemon et al, 2001). Its biomass can double in 16 h to 2 days under optimal conditions (Leng, 1999).…”

“…Strain FID3 can colonize sterile S. polyrhiza roots and exert BPA-degrading activity on the roots. Duckweed species (Lemnaceae), including S. polyrhiza, reproduce by vegetative reproduction during the growing season (Lemon et al, 2001). That is, next-generation plants are produced and released from the mother plant.…”

Bisphenol A (BPA) is a well-known toxic and endocrine-disrupting compound frequently detected in aquatic environments. Here, we investigated rhizoremediation of BPA-polluted water using giant duckweed (Spirodela polyrhiza). One BPA-degrading bacterium, Novosphingobium sp. FID3, was isolated from the S. polyrhiza roots. Strain FID3 utilized BPA as a sole carbon and energy source. Organic compounds from S. polyrhiza roots supported cell growth of strain FID3, and the strain colonized the sterile S. polyrhiza roots, where it degraded BPA. Strain FID3 colonizing the S. polyrhiza roots was passed down from mother plant to first-and second-generation daughter plants during vegetative reproduction. S. polyrhiza in association with strain FID3 repeatedly removed BPA from secondary effluent water polluted with BPA, whereas S. polyrhiza alone could not remove BPA. Hydroponic systems using S. polyrhiza in association with the BPA-degrading rhizobacterium Novosphingobium sp. FID3 have the potential to be effective and sustainable treatments for BPA-polluted waters.

“…Usually, the Allee effect has been associated with flowering plants because of the pollen transfer rate (Lundberg et al 1998). Much as L. gibba is a flowering plant, it reproduces mostly by vegetative propagations (Landolt 1986;Lemon et al 2001;Peltre et al 2002). Therefore, the exhibition of the Allee effect in L. gibba would be less associated to pollen transfer rate.…”

To narrow the differences between the results obtained from radionuclides and heavy metal ecotoxicity investigations in the laboratory and in the abandoned uranium mines, a few standardised plant bioassay procedures were selected from the literature for testing with Lemna gibba L. The bioassay procedures were tested in situ and ex situ. The laboratory culturing was performed in batch and semicontinuous modes. The results revealed that most of the standardised plant bioassay procedures require modification for the L. gibba bioassay to predict the actual effects under field conditions. L. gibba performed relatively better in the field than laboratory batch cultures despite that the batch cultures had many-fold higher nutrient concentrations than in the field. For instance, the phosphorus concentration of the mine tailing water was 0.13 ± 0.09 lg l À1 in the field, while the literature range for phosphorus in the laboratory culture media is 13.6-40 mg l À1 . L. gibba growth in the laboratory batch culture was influenced by speciation changes due to consumption of nutrients, CO 2 and O 2 phase exchanges, and excretion of organic substances by the test plants. Semicontinuous culture modes performed significantly better than batch cultivation even after 10· dilution of the nutrient solution. The growth behaviour revealed that L. gibba exhibited intrapopulation and probiotic interaction for best performance. Growth performance of L. gibba was influenced by the anions that balanced essential cations despite equal cation concentration in the culture media; e.g., the best growth was observed in culture media that had more SO 4 2À than Cl À . Water samples from the field had higher SO 4 2À concentrations than Cl À . The test vessel material, sterilisation and axenic culturing procedures also influenced the sensitivity of the bioassay. These, for instance, and a few others are neither described nor reported in most standard Lemna tests or the literature. Thus, this work presents results of a series of tests conducted on the selected methods. Common and possible errors and corrective measures in assigning L. gibba bioassay from laboratory population levels to field community levels are discussed.
