TL;DR: Results demonstrated that cell division of Chlorella vulgaris increased at 24 h and decreased at 96 h after exposure to different concentrations of GO, and high concentrations of 10 mg/L GO weakened the carbon fixation process in algal cells.

TL;DR: In this article, metagenomic sequencing was employed to analyze the movability of ARGs, their potential transfer, and possible hosts in photobioreactor treating urban water, and the results indicated that 20mg/L of CCN significantly decreased the absolute abundance and ARGs proportions which mediated by plasmids (32.7%).

TL;DR: The physiological impacts and interactions of antibiotic resistance gene (ARG) abundance, microcystin synthetase gene expression, graphene oxide (GO), andMicrocystis aeruginosa in synthetic wastewater were investigated and demonstrated that the absolute abundance of sul1, sul2, tetW, and tetM in synthetic Wastewater dramatically increased when the GO concentration was 0.01 mg/L.
Abstract: The physiological impacts and interactions of antibiotic resistance gene (ARG) abundance, microcystin synthetase gene expression, graphene oxide (GO), and Microcystis 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.

TL;DR: In this paper, a blue light (465 nm) emission after ultraviolet (380 nm) excitation into the microalgae growth media was demonstrated that the ultraviolet light was effectively absorbed and utilized by the chlorophyll in the GOQDs-Chlorella pyrenoidosa system, resulting in a significantly increased photosynthetic activity.
