“…We have witnessed that 100% of the floodplain water body, with nearly 80% of the drainage canal covered with mats of plants. Even 50% of the water surface area covered by Pistia stratiotes is a real threat to the immersed species, sensitive to light, oxygen content and pH level (Olkhovich et al, 2017). Such mats limit development of macrophytes through shading and a mechanical barrier which prevents enriching water with oxygen due to atmospheric aeration.…”

We have analyzed structural and dynamic characteristics (production, morphometric parameters, phytocoenotic features and invasive behavior) of two locations with the alien species Pistia stratiotes L. in different types of water bodies, by origin, use and trophic status (a drainage canal and oxbow lake) in the outskirts of Kyiv. It is possible that in the case of increased anthropogenic eutrophication due to inorganic nitrogen, mother plants become smaller and more compact. The variability of morphological features increases. We also have distinguished growth of invasive potential of the species in the conditions of the water bodies of the region.

“…This has become one of the main reasons for the change in the species composition of biota, in particular the reduction of aboriginal species [7]. In this regard, such phenomena as uncontrolled outbreaks of growth of various alien monospecies populations of aquatic macrophytes have become more frequent in the aquatic ecosystems of Ukraine [8]. Pistia stratiotes L. is one of the ecologically dangerous alien aquatic macrophytes.…”

“…The problem of spontaneous distribution of invasive aquatic macrophytes, in particular P. stratiotes, is relevant in Ukraine. This is due to climate change and rising temperatures in the winter [8]. Rapid distribution of the species in the lowlands of the Dnister River and in the Dnipro and Siversky Donets Rivers has been reported [33].…”

Anaerobic Degradation of Environmentally Hazardous Aquatic Plant Pistia stratiotes and Soluble Cu(II) Detoxification by Methanogenic Granular Microbial Preparation

et al. 2021

The aquatic plant Pistia stratiotes L. is environmentally hazardous and requires effective methods for its utilization. The harmfulness of these plants is determined by their excessive growth in water bodies and degradation of local aquatic ecosystems. Mechanical removal of these plants is widespread but requires fairly resource-intensive technology. However, these aquatic plants are polymer-containing substrates and have a great potential for conversion into bioenergy. The aim of the work was to determine the main patterns of Pistia stratiotes L. degradation via granular microbial preparation (GMP) to obtain biomethane gas while simultaneously detoxifying toxic copper compounds. The composition of the gas phase was determined via gas chromatography. The pH and redox potential parameters were determined potentiometrically, and Cu(II) concentration photocolorimetrically. Applying the preparation, high efficiency of biomethane fermentation of aquatic plants and Cu(II) detoxification were achieved. Biomethane yield reached 68.0 ± 11.1 L/kg VS of Pistia stratiotes L. biomass. The plants’ weight was decreased by 9 times. The Cu(II) was completely removed after 3 and 10 days of fermentation from initial concentrations of 100 ppm and 200 ppm, respectively. The result confirms the possibility of using the GMP to obtain biomethane from environmentally hazardous substrates and detoxify copper-contaminated fluids.

This work purpose was to find the impact of Pistia stratiotes L., 1753 - a new species on the territory of Ukraine, on the vitality of other free-floating hydrophytes so-called pleuston- Salvinia natans (L.) All., 1785, S. laevigatum (Humb. and Bonpl. ex Willd.) Heine, 1968, to determine the degree of stability and competitiveness of these species for resources in natural ecosystems relatively to the undesirable species. To find out the influence of P. stratiotes on other free-floating on the water surface plant species which compete for elements of nutrition among each other, we have investigated changes in the content of photosynthetic pigments in S. laevigatum and S. natans, which were exhibited with P. stratiotes for 14 days. Besides changes in water indices, oxygen content, mineralization and pH, were measured.
