BACKGROUND: The results of field long‐term experiments (initiated by the first author) showed that laser photostimulation could significantly increase the adaptability of different plant species (the willow Salix sp., elephant grass Miscanthus giganteus, Virginian mallow Sida hermaphrodita, common reed Phragmites australis, etc.) to contaminated environment. The attempts to increase the bioremediation efficiency of contaminated soil and water were made with the application of laser biotechnology. An optimal algorithm of laser biostimulation for selected biological materials for more efficient bioremendiation of selected pollutants was verified by sensitive biotests. RESULTS: Laser irradiation of hydrophytes Lemna minor accelerated the phytoremediation of phosphorus and nitrogen compounds from wastewater and increased the surface area of the duckweed and biomass production. Ecological efficiency of innovative bioremediation versus traditional methods could be tested using computer‐based image analysis of selected components of aquatic ecosystems (e.g. Lemna sp., Lymnaea stagnalis, Daphnia sp., Hydra sp.) and highly sensitive to different pollutants juvenile stages of the tested animals. CONCLUSIONS: Such an innovative bioremediation method and biotests would be useful for verification of new bioremediation methods and for better reproduction of biological resources and efficient protection of biodiversity in aquatic ecosystems.

“…They have a great ability to take up and store many dissolved substances. They are therefore used in wastewater treatment, also in temperate climates ( Ozimek, 1998 ; Bekcan, Atar & Abdullah, 2009 ). The use of native species in the treatment, which the analysed duckweed species are for the European territory, is extremely important ( Wright & Jones, 2006 ).…”

Preliminary studies of selected Lemna species on the oxygen production potential in relation to some ecological factors

Dissolved oxygen is fundamental for chemical and biochemical processes occurring in natural waters and critical for the life of aquatic organisms. Many organisms are responsible for altering organic matter and oxygen transfers across ecosystem or habitat boundaries and, thus, engineering the oxygen balance of the system. Due to such Lemna features as small size, simple structure, vegetative reproduction and rapid growth, as well as frequent mass occurrence in the form of thick mats, they make them very effective in oxygenating water. The research was undertaken to assess the impact of various species of duckweed (L. minor and L. trisulca) on dissolved oxygen content and detritus production in water and the role of ecological factors (light, atmospheric pressure, conductivity, and temperature) in this process. For this purpose, experiments were carried out with combinations of L. minor and L. trisulca. On this basis, the content of oxygen dissolved in water was determined depending on the growth of duckweed. Linear regression models were developed to assess the dynamics of changes in oxygen content and, consequently, organic matter produced by the Lemna. The research showed that the presence of L. trisulca causes an increase in dissolved oxygen content in water. It was also shown that an increase in atmospheric pressure had a positive effect on the ability of duckweed to produce oxygen, regardless of its type. The negative correlation between conductivity and water oxygenation, obtained in conditions of limited light access, allows us to assume that higher water conductivity limits oxygen production by all combinations of duckweeds when the light supply is low. Based on the developed models, it was shown that the highest increase in organic matter would be observed in the case of mixed duckweed and the lowest in the presence of the L. minor species, regardless of light conditions. Moreover, it was shown that pleustophytes have different heat capacities, and L. trisulca has the highest ability to accumulate heat in water for the tested duckweed combinations. The provided knowledge may help determine the good habitat conditions of duckweed, indicating its role in purifying water reservoirs as an effect of producing organic matter and shaping oxygen conditions with the participation of various Lemna species.

“…The results show that all COD values are within the standard thresholds. The long-term optimum temperature for L. minor growth is 26 °C [14]. The minimum and maximum temperatures are 4 and 33 °C, respectively.…”

“…Lemna minor is a very small free-floating macrophyte growing rapidly and adapting easily to various environmental conditions in stagnant and slow-flowing watercourses [1,13]. Lemna accumulates and assimilates contaminants in aquatic systems [14] and can be utilised for metal removal [6]. This plant is often used as a fodder due to elevated protein concentrations and a lack of fibre [14,15].…”

The study assesses the performance of experimental wetland pond systems vegetated by Lemna minor L. (common duckweed or lesser duckweed) for textile azo dye removal. The objectives are to assess the influence of L. minor on water quality parameters, compare the dye and chemical oxygen demand (COD) removal of four dyes (Acid Blue 113, Reactive Blue 198, Direct Orange 46 and Basic Red 46) with each other, and monitor the effect of dye accumulation as a function of the relative growth rate (RGR) of L. minor. Findings indicate that the simulated shallow pond systems remove BR46 (low concentration) significantly (p < 0.05) higher than other dyes, and the ponds containing L. minor outperformed control ponds by around 51% in mean removal efficiency with a potential of L. minor for phytoremediation of approximately 13% efficiency.
