摘要: Abstract Mono-cultured and mix-cultured duckweed species were investigated with respect to the function of their associated microbial communities in heavy metal contaminated wastewater. Results show that carbon source utilization patterns L. aequinoctialis- S. polyrhiza-associated different. The relationships between activity, antioxidant enzyme activity (CAT, GSH, SOD) growth was positive significant. L. aequinoctialis S. polyrhiza mixture higher than monoculture low high metal, respectively, thereby altering specific types increasing when compared monocultured duckweed. Furthermore, results indicate are protected from damage through regulation bacterial communities.
