Summary: In order to achieve environmental sustainability, a raw bloom-forming species Microcystis aeruginosa was used for the biosorption of uranium without any modification. The adsorption experiments showed that the process of U(VI) adsorption on M. aeruginosa was pH-dependent, endothermic and spontaneous. The analysis of FTIR and XPS indicated the significant role of oxygenated functional groups of M. aeruginosa in uranium biosorption. The high adsorption capacity and satisfactory regeneration availability of M. aeruginosa enable the possibility of treating 'polluter (radioactive wastewater)' with 'polluter (toxic cyanobacteria)'.

Summary: The simplest beta-diketone, acetylacetone, is found to be a promising specific cyanocide, targeting bound iron species in the photosynthetic electron transport chain of Microcystis aeruginosa. This targeted binding approach outperforms the general oxidation mechanism in terms of specificity and eco-safety, providing a unique solution for the selective control of cyanobacteria.

Summary: Protopine has been found to significantly inhibit the growth of M. aeruginosa TY001, mainly through downregulating stress response and DNA repair genes, reducing antioxidant enzyme activities, and increasing malondialdehyde levels in cells. These results suggest that protopine may have potential value in aquatic management strategies as a component that targets oxidative and DNA damage mechanisms in controlling and eliminating harmful algal blooms.

Summary: This study investigated the toxic effects of the antibiotic ofloxacin (OFL) on the cyanobacterium Microcystis aeruginosa under different exposure scenarios, including a single high dose and multiple additions of low concentrations. The results showed that the highest OFL level inhibited cellular growth, chl-a content, and cell size of M. aeruginosa, while higher doses induced stronger chl-a autofluorescence. Repeated low OFL doses significantly increased the metabolic activity of M. aeruginosa compared to a single high dose. Viability and cytoplasmic membrane were not affected by OFL exposure, but oxidative stress was observed with fluctuating responses.

Summary: This study evaluated the application of Fv/Fm to cyanobacteria using controlled experiments on a single isolate. The results showed significant differences in Fv/Fm estimates among PAM fluorometers for light- versus dark-adapted cell suspensions, with no effect of dark adaptation on Fv/Fm across a single nutrient treatment. All Fv/Fm methods could distinguish between different nutrient limitations, but not all specific nutrient stresses were resolved.

Summary: Plant-derived extracts have different effects on cyanobacterial cells, with walnut husk and rose leaf extracts causing cell death and necrosis, and kudzu leaf extract inhibiting cell growth. Transcriptomic and biochemical research revealed that these extracts have different inhibitory effects on critical genes related to carbon fixation and cell wall synthesis.

Summary: This study used iTRAQ-based proteomics to investigate the effects of phosphorus depletion on Microcystis aeruginosa, showing that phosphorus depletion inhibits cell growth and primary metabolic processes while maintaining photosystem integrity, and influences the balance of carbon, nitrogen, and phosphorus in the cells.

Summary: High calcium concentration induces colony formation in algae by shifting from cell adhesion to cell division. Algae respond to this calcium-induced pressure by aggregating through the secretion of extracellular polysaccharides and cell adhesion. Although high calcium concentrations cannot completely inhibit algal cell growth, they delay the algae from entering the rapid growth phase.

Summary: The study highlights the physiological and transcriptomic changes of Microcystis aeruginosa supplied with different nitrogen forms (nitrate and ammonium). The results show that ammonium stimulates initial growth better than nitrate, but excess absorbed light energy under high ammonium leads to cellular damage. Adequate nitrate supply promotes efficient photosynthesis and higher biomass yield. The different nitrogen forms also induce different transcriptomic patterns in M. aeruginosa. These findings provide important clues for understanding the effects of nitrogen forms on cyanobacterial outbreaks.

Summary: Aphelids are intracellular parasitoids of algae and represent an early-diverging lineage of the kingdom Fungi. A novel aphelid strain, KS114, parasitizing selenastracean green algae, was investigated and described as a new species, Aphelidium parallelum, based on its unique ultrastructure features and molecular phylogenetic analysis.

Summary: This study conducted phenotypic and genomic analyses of a freshwater alphaproteobacterial lineage called 'Candidatus Phycosocius' and discovered a new species called 'Ca. Phycosocius spiralis'. Phylogenomic analyses revealed that the CaP clade is a deeply branching lineage in the Caulobacterales. Pangenome analyses identified characteristic features of the CaP clade, such as aerobic anoxygenic photosynthesis and essential vitamin B auxotrophy. The study also suggested that horizontal transfers of quorum sensing genes and interactions with specific algal partners may drive CaP clade diversification.
