“…One paper examined patterns of community composition before and after major dam construction , and other 5 papers used data from c. 10-20 years, coinciding with popularization of longterm ecological programs and standard ecological assessments. Two contributions used a space-for-time substitution by comparing beta diversity between communities with and without occurrence of invasive crayfish species (Larson & Pool, 2020) and before and after the biological control of a major invasive macrophyte (Coetzee et al, 2020). The majority of the studies found evidence for BH, suggesting its pervasiveness across geographical regions and taxonomic groups.…”

“…In another study, Coetzee et al (2020) showed that the invasive macrophyte water lettuce caused BH in associated macroinvertebrates, by comparing nearby sites with and without the invasive plant. But after applying a biological control agent to reduce water lettuce abundance, macroinvertebrates were found to increase in diversity leading to biotic differentiation.…”

“…Single specimens of the plant were found both in the city hydrographic network and in the shallow water of the Dnipro River near Kyiv [34]. It has been experimentally confirmed that after the removal of invasive freshwater plants, including P. stratiotes, the biodiversity of water bodies is restored [35]. Various methods are used to control these weeds in aquatic environments (e.g., preventive, mechanical, biological, and chemical).…”

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.

“…It grows in the local water bodies, lakes, rivers, dominated by high nitrogen, phosphorus, mineral, and heavy metals. Every so often, the exceed density of water hyacinth in water bodies causes disturbances to other living floral and faunal communities (Coetzee et al 2020). In the area of Haridwar, India, water hyacinth is a common aquatic plant found in most of the local village ponds, lakes, and canals.…”

This study aimed to explore the effectiveness of water hyacinth (Eichhornia crassipes) for heavy metals reduction from highly toxic glass industry effluent. Based on a 40 days laboratory-scale experiment, a total of five diluted concentrations of glass industry effluent were selected to cultivate water hyacinth. Furthermore, the kinetics and prediction models were used to analyze the metals reduction data to understand the plant behavior during the phytoextraction of heavy metals. Results suggested that water hyacinth was capable to reduce Cd (91.30%), Cu (93.55%), Fe (92.81%), Mn (93.45%), Pb (89.66%), and Zn (94.44%) metals most efficiently in 25% glass industry effluent concentration, respectively. Moreover, the growth performance of the water hyacinth plant exhibited the maximum fresh plant biomass (254.90 ± 3.75 g), chlorophyll (3.53 ± 0.11 mgg −1 fwt.), and relative growth rate (0.0026 gg −1 d −1 ) using 25% dilution treatment, respectively. Additionally, the firstorder model gave the best fitting results in terms of the coefficient of determination (R 2 > 0.82) and rate constant (k > 0.023 mgL −1 d −1 ). Besides this, prediction modeling using multiple regression helped to construct mathematical equations to predict the heavy metals absorbed by water hyacinth plant tissues which were further supported by model efficiency (> 0.80) and normalized error tools (< 0.02). The results of this report are novel and have the utmost importance for the eco-friendly and sustainable treatment of glass industry effluent.
