摘要：The macrophyte plants Lemnaceae are abundant in the tropical and subtropical regions but now present in the Danube Delta. The plant grows in water with high levels of N,P,and K,synthesizing protein at a remarkable rate. Used as food and feed in some regions it is currently attracting interest especially for its ability to metabolize and purify wastewater. Our culture technique of duckweed was standardized in water tanks and a series of analytical methods for determining the chemical parameters of waste water were optimized. Phenotypic biodiversity of the aquatic communities was analyzed using the Biolog Ecoplates system on a total of eight samples,concluding in a symbiosis between the plants and the microbial community that can be linked to Lemnaceae high wastewater purification abilities,that transforms the highly toxic environment into an environment conducive to the development of aerobic organisms.
