“…Such microalgal strains possess uplifted tolerance towards heavy metals [ 104 , 234 , 235 , 236 , 237 ]. Increased tolerance can be also induced on laboratory scale by applying proper metal dosages [ 238 , 239 ] or metal-containing wastes [ 240 ]. It results in development of physiologically adapted strains [ 61 , 239 , 241 ] or metal resistant mutants due to rare spontaneous mutations that occur before metal treatment [ 61 , 238 , 239 ].…”

“…Additionally, an amount of microalgae biomass in relation to metal concentration should be taken into consideration, as high biomass densities can alleviate detrimental effect of metal ions on microalgae cells in culture [ 259 , 260 ]. The use of older culture inocullum also improved resistance of Scenedesmus quadricauda against Ag nanoparticles [ 239 ]. Synergistic effects of different heavy metal ions [ 261 ] or metal ions with nanoparticles (see Section 4.2.3 ) on microalgae cells, should be also taken into consideration.…”

Microalgae are a source of numerous compounds that can be used in many branches of industry. Synthesis of such compounds in microalgal cells can be amplified under stress conditions. Exposure to various metals can be one of methods applied to induce cell stress and synthesis of target products in microalgae cultures. In this review, the potential of producing diverse biocompounds (pigments, lipids, exopolymers, peptides, phytohormones, arsenoorganics, nanoparticles) from microalgae cultures upon exposure to various metals, is evaluated. Additionally, different methods to alter microalgae response towards metals and metal stress are described. Finally, possibilities to sustain high growth rates and productivity of microalgal cultures in the presence of metals are discussed.

Nanoparticle toxicology works toward establishing the hazard of nanoparticles, and therefore their potential risk, in light of the increased use of exposure. The current study was research proper characterization of the nanoparticles for understanding of their toxic effects and mechanisms at the cellular level. Dose and time as a main parameters is essential in hazard identification and risk assessment of nanomaterials. Material for the evaluation of toxic effects was used 20 samples of commercially available and laboratory preparations of metals and nanocarbon, divided into main groups: carbon nanoparticles, metal oxide nanoparticles and metal nanoparticles in different concentration. Fresh water infusoria stylonychia mytilus (wild strain) in exponential growth phase was used as the test object. Analysis of data on oxides of the metals showed higher toxicity than metal nanoparticles. In groups the maximum toxicity was observed in iron oxides (Fe3O4, Fe2O3), copper (CuO) and molybdenum (MoO3) (0,1; 0,025; 0,0125 М) after 24 hours of incubation with the test object Analysis of the effect of metal nanoparticles on the cells of infusoria showed that the maximum toxic effect was observed when exposed to Cu, Fe, Ag (0,025-0,0015625 М). Statistical analyses showed a high correlation between concentration and time (P≤0,001). The issue of accessibility of nanomaterials released in the environment for living organisms has been poorly studied. The toxic effects of nanoparticles can be associated with their size and their physicochemical properties.

“…During exposure time, resistant microalgal cells were selected and became the majority of population. These resistant cells were produced accidentally during cell division by rare spontaneous mutations [36]. It was shown that, similar to microalgal cells, bacterial cells are also sensitive to ironbased nanoparticles in a short exposure time (5-day) [37,38].…”

Despite iron-based nanoparticles gaining huge attraction in various field of sciences and technology, their application rises ecological concerns due to lack of studies on their interaction with microbial cells populations and communities, such as biofilms. In this study, Chlorella vulgaris cells were employed as a model of aquatic microalgae to investigate the impacts of l-lysine-coated iron oxide nanoparticles (lys@IONPs) on microalgal growth and biofilm formation. In this regard, C. vulgaris cells were exposed to different concentrations of lys@IONPs and the growth of cells was evaluated by OD600 and biofilm formation was analyzed using crystal violet staining throughout 12 days. It was revealed that low concentration of nanoparticles (< 400 µg/mL) can promote cell growth and biofilm formation. However, higher concentrations have an adverse effect on microalgal communities. It is interesting that microalgal growth and biofilm are concentration- and exposure time-dependent to lys@IONPs. Over long period (~ 12 days) exposure to high concentrations of nanoparticles, cells can adapt with the condition, so growth was raised and biofilm started to develop. Results of the present study could be considered in ecological issues and also bioprocesses using microalgal cells.
