“…The content of amino acids decreases, and the compositions of fatty acids vary under adverse conditions (Liang et al, 2020; Ota et al, 2009). Huang et al (2021) have illustrated that Cu 2+ , nano‐Cu and nano‐CuO decrease the amino acid content per cell and the total algae‐derived output of marine microalgae by decreasing phytoplankton growth. Studies have demonstrated that the composition of algal fatty acids was altered by inorganic contaminants (such as metals and pesticides) (Filimonova et al, 2016; Tayemeh et al, 2020).…”

To develop an effective technique for decreasing rotifer contamination in Spirulina platensis cultivation, the effects of 5‐fluoro‐2'‐deoxyuridine (FUdR; 0, 60, 110, 160, 210, and 260 μg/L) on the development, reproduction and population growth of the rotifer, Brachionus plicatilis and on the growth, photosynthetic properties and nutritional composition of S. platensis were investigated. The results showed that the negative effects of FUdR on the pre‐reproductive period, the number of total eggs per female and the egg hatching rate of rotifers were dose‐dependent. The egg hatching of rotifers was fully inhibited by exposure to 260 μg/L FUdR. The effects of FUdR on the biomass, maximum quantum yield (Fv/Fm), effective quantum yield (φPSII), amino acid content and fatty acid composition of S. platensis were not significant. Therefore, these results suggest that FUdR has excellent potential for controlling grazing zooplankton contamination in microalgal cultivation.

“…Metal salt (Cu 2+ ), nano-metal (nano-Cu), and nanometal oxide (nano-CuO) prohibit the growth of marine phytoplankton Skeletonema costatum and Nitzschia closterium. It has been observed that Cu 2+ and nano-Cu EC 50 values from 0.356 to 0.991 mgL -1 and 0.663 to 2.455 mgL -1 affect the secretion of extracellular polymeric substances and amino acids in S. costatum and N. closterium [33]. Attheya ussuriensis (Bacillariophyceae), Chaetoceros muelleri (Bacillariophyceae), Heterosigma akashiwo (Raphidophyceae) and Porphyridium purpureum (Rhodophyceae) were exposed to two types of multiwalled silica nanotubes SNT-1 and SNT-2 for 96 h (7 days) and reported that the growth rate was affected for only C. muelleri and P. purpureum [34].…”

Biodiesel is nontoxic and perishable and is created by combining alcohol with edible fat, animal fat, or used cooking oil. Considering the food issues, microalgae gain the utmost attention to be used as biofuel producers. According to the study, biomass-based biofuels offer excellent potential to address energy scarcity in a sustainable manner [3]. The environmentally beneficial method of producing biodiesel has attracted the interest of scientists worldwide [4]. The effectiveness and cost-reduction of microalgal biodiesel synthesis continue to be major barriers to its optimal development because it is a sequential process [5]. The costliest of the four production processes is cultivation (>40% of the overall cost). Among the four production methods, cultivation stands out as the most expensive (>40% of the total expenses). To achieve a significant biomass concentration, it is essential to gather microalgae [6]. Consequently, substantial quantities of water need to be acquired from the production procedures, which entails financial expenditure and energy consumption. It is estimated that around 30% of the overall production cost could be attributed to the expenses related to harvesting [7]. To accomplish energy-effective

“…Exposure to 50 nm CeO 2 NPs, 50 nm CuONPs or 30-50 nm ZnONPs has led to an increase of both tightly and loosely bound EPS of cyanobacterium M. aeruginosa (Hou et al, 2017). It has been suggested that the enhanced EPS production by phytoplankton species when exposed to ENPs lowered collisions between microalgae and the ENPs by decreasing the specific contact area, and thus alleviated CuONPs toxicity in two diatoms S. costatum and N. closterium (Huang et al, 2022). CuONPs enhanced the production of both soluble and cell bounded EPS of C. pyrenoidosa, that consequentially enhance the hetero-aggregation of the ENPs (Zhao et al, 2016).…”

Based on the up-to-date knowledge we critically discuss the current understanding of the influence of the compounds secreted by phytoplankton species on the fate of metal-containing engineered nanoparticles (ENPs) in aquatic settings. Different biomolecules, such as extracellular polymeric substances (EPS) and exometabolites play important, yet to elucidate, role in the dissolution, colloidal stability, transformations and biouptake of the ENPs and thus shape their behavior within the phycosphere. Phytoplankton secretions can also mediate the synthesis of ENPs from dissolved ions by reducing the metals ions and capping the newly formed ENPs. However, the environmental significance of this process remains to be demonstrated. Exposure to ENPs triggers changes in the secretion of the biomolecules. An improved understanding of the regulatory mechanism and exometabolite changes due to ENP exposure is essential for deciphering the ENPs-phytoplankton interactions. Unveiling the significance of secreted biomolecules in modulating the behavior of the metal-containing ENPs is central for understudying the phytoplankton-ENPs feedbacks, drivers of transformations of ENPs and their mechanisms in the aquatic environment.
