“…, respectively. It has already been shown in some studies that the metals like Pb and Zn were tolerated by L. minor at 0.4, 0.4, 3 and 15 mg/l, respectively (Khellaf and Zerdaoui 2009;Sasmaz et al 2015). In our observations, it is evident that the duckweeds tolerate the zinc up to 10 mg/l.…”

Plants have gained importance in situ bioremediation of heavy metals. In the present study, different concentrations of zinc (Zn 2? ) (0.5, 5, 10, 15, 20 mg/l) and lead (Pb 2? ) (1, 2, 4, 6, 8 mg/l) were used to evaluate metal tolerance level of Lemna minor. L.minor were exposed to metals for 4 days and tested for its dry to fresh weight ratio (DW/FW), photosynthetic pigments production and protein content. The oxidative damage was detected by measuring catalase activity. L.minor showed tolerance against Zn and Pb 2? toxicity up to the concentration of 10 and 4 mg/l, respectively. Hence, the metal tolerant property of this plant shall be exploited for bioremediation of Zinc and Lead in polluted water. Further, the detailed and wide range of heavy metal toxicity studies should be done to reveal the possible use of this plant on large scale bioremediation purpose.

“…Of the different techniques for removing of heavy metals, phytoremediation is among the cost-effective and ecologically friendly, in that it uses living green plants for in situ removal of contaminants from water and soil (Sood et al 2012;Tatar & Obek 2014;Goswami et al 2014;Sasmaz et al 2015).

This study investigated the use of Lemna gibba and Lemna minor plant species to absorb Cr, Ni and Co from Alacakaya mining area water. Lemna gibba and L. minor were separately placed to feed into two reactors. Water and plant samples were collected for eight consecutive days, and the pH, electric conductivity and temperature of the water were measured. The plants were washed, dried and burned at 300°C for 24 h in a drying oven. The samples were then analysed by ICP‐MS (inductively coupled plasma mass spectroscopy) for concentrations of Cr, Ni and Co, which were 1.2, 0.9 and 0.5 μg L−1 respectively. On Day 8, the determined uptake of L. gibba and L. minor were: 196 and 398% for Cr; 307 and 1473% for Ni; and 166 and 223% for Co respectively. Lemna gibba and L. minor were thus effective in absorbing Cr, Ni and Co from mining water.

“…The differences across duckweed populations and microbial communities we see here may alter the potential of duckweed to remediate environments contaminated with zinc or other pollutants. Others have postulated that duckweed may be of interesting and unique value in phytoremediation of water (Mkandawire and Dudel, 2007; Ziegler et al, 2016), specifically due to its uptake or modification of a wide variety of aquatic pollutants (Mo et al, 1989; Stout and Nüsslein, 2010; Stout et al, 2010; Sekomo et al, 2012; Uysal, 2013; Sasmaz et al, 2015; Baciak et al, 2016; Gatidou et al, 2017; Gomes et al, 2017). Plant-associated microbes are often in part responsible for removal or detoxification of contaminants, and presence of various taxa on duckweed may alter its phytoremediation potential (Toyama et al, 2009; Zhao et al, 2015).…”

1The picture emerging from the rapidly growing literature on host-associated micro-2 biota is that host traits and fitness often depend on complex and interactive effects 3 of host genotype, microbial interactions, and abiotic environment. However, testing 4 these main and interactive effects typically requires large, multi-factorial experiments 5 and thus remains challenging in many systems. Furthermore, most studies of plant 6 microbiomes focus on terrestrial hosts and microbes. Aquatic habitats may confer 7 unique properties to plant micriobiomes. We grew different populations of duck-8 weed (Lemna minor ), a floating aquatic plant of increasing popularity in freshwater 9 phytoremediation, in three microbial treatments (adding no, "home", or "away" 10 microbes) at two levels of zinc, a common water contaminant in urban areas. Thus, 11 we simultaneously manipulated plant source population, microbial community, and 12 the abiotic environment, and measured both plant and microbial performance as 13 well as plant traits. Although we found little evidence of interactive effects, we found 14 strong main effects of plant source, microbial treatment, and zinc on both duckweed 15 and microbial growth, with significant variation among both duckweed and microbial 16 communities. Despite strong growth alignment between duckweed and microbes, zinc 17 consistently decreased plant growth, but increased microbial growth. Furthermore, 18 as in recent studies of terrestrial plants, microbial interactions altered a duckweed 19 phenotype (frond aggregation). Our results suggest that the duckweed source pop-20 ulation, its associated microbiome, and the contaminant environment may all need 21 to be considered in real-world phytoremediation efforts. Lastly, we propose that 22 duckweed microbes offer a robust experimental system for study of host-microbiota 23 interactions under a range of environmental stresses.24
