“…Specifically, increased levels of carbohydrates and numerous unsaturated fatty acids including D-glucose, galacturonate, linoleic acid, glutaric, and tetradecanoic acid were observed. The increase of glycometabolism indicates the vigorous growth of algal cell (Zhang et al 2018), and unsaturated fatty acid will promote the photosynthetic performance of algal cells (Anto et al 2020).…”

“…The ARGs and mcyA-J were significantly related with photosynthetic metabolites including phytol (an essential component of chlorophyll) and 3-6-anhydro-D-glucose (photosynthetic carbon fixes important metabolites) (Zhang et al 2018). Moreover, some studies have demonstrated that microcystin synthetase genes (mcyA-J) and MCs production was a kind of physiological response to environmental stressed factors (Li et al 2019).…”

The physiological impacts and interactions of ARGs abundance, microcystin synthetase genes expression, GO, and M. aeruginosa in synthetic wastewater were investigated. The results demonstrated that the absolute abundance of sul1, sul2, tetW, and tetM in synthetic wastewater dramatically increased to 365.2%, 427.1%, 375.2%, and 231.7%, respectively, when the GO concentration was 0.01 mg/L. Even more interesting is that the sum gene copy numbers of mcyA-J also increased to 243.2%. The appearance of GO made the significant correlation exist between ARGs abundance and mcyA-J expression. Furthermore, M. aeruginosa displayed better photosynthetic performance and more MCs production at 0.01 mg/L GO. There were 65 pairs of positive correlations between the intracellular differential metabolites of M. aeruginosa and the abundance of sul1, sul2, tetM, and tetW with various GO concentrations. The GO will impact the metabolites and metabolic pathway in M. aeruginosa. The metabolic changes impacted the ARGs, microcystin synthetase genes, and physiological characters in algal cells. Furthermore, there were complex correlations among sul1, sul2, tetM, tetW, mcyA-J, MCs, photosynthetic performance parameters, and ROS. The different concentration of GO will aggravate the hazards of M. aeruginosa by promoting the expression of mcyA-J, producing more MCs, simultaneously, it may cause the spread of ARGs.

“…In this case, a comparable response to that of anthracene was obtained (Patel et al 2013; Kumar et al 2014). Very recently, Zhang et al (2018) studied the effects of pyrene and naphthalene on the growth rate, phycobiliprotein concentration, microcystin content and antioxidant enzyme activity of Microcystis aeruginosa . The results of those experiments revealed that the growth of the cyanobacterium was modified and the phycobiliprotein content was decreased, whereas the production of a microcystin-specific toxin was promoted by the presence of the tested chemicals.…”

Cyanobacteria, also known as blue-green (micro)algae, are able to sustain many types of chemical stress because of metabolic adaptations that allow them to survive and successfully compete in a variety of ecosystems, including polluted ones. As photoautotrophic bacteria, these microorganisms synthesize aromatic amino acids, which are precursors for a large variety of substances that contain aromatic ring(s) and that are naturally formed in the cells of these organisms. Hence, the transformation of aromatic secondary metabolites by cyanobacteria is the result of the possession of a suitable “enzymatic apparatus” to carry out the biosynthesis of these compounds according to cellular requirements. Another crucial aspect that should be evaluated using varied criteria is the response of cyanobacteria to the presence of extracellular aromatic compounds. Some aspects of the relationship between aromatic compounds and cyanobacteria such as the biosynthesis of aromatic compounds, the influence of aromatic compounds on these organisms and the fate of aromatic substances inside microalgal cells are presented in this paper. The search for this information has suggested that there is a lack of knowledge about the regulation of the biosynthesis of aromatic substances and about the transport of these compounds into cyanobacterial cells. These aspects are of pivotal importance with regard to the biotransformation of aromatic compounds and understanding them may be the goals of future research.
