What makes a cyanobacterial bloom disappear? A review of the abiotic and biotic cyanobacterial bloom loss factors

Harmful Algae, Journal Year: 2024, Volume and Issue: 133, P. 102599 - 102599

Cyanobacterial blooms present substantial challenges to managers and threaten ecological public health. Although the majority of cyanobacterial bloom research management focuses on factors that control initiation, duration, toxicity, geographical extent, relatively little role loss processes in how these are regulated. Here, we define a process terms population dynamics as any removes cells from population, thereby decelerating or reducing development extent blooms. We review abiotic (e.g., hydraulic flushing oxidative stress/UV light) biotic allelopathic compounds, infections, grazing, resting cells/programmed cell death) known govern loss. found dominant depend several system specific including genera-specific traits, situ physicochemical conditions, microbial, phytoplankton, consumer community composition. also address context discuss perspectives predicting changing climate may directly indirectly affect A deeper understanding their underlying mechanisms help mitigate negative consequences improve current strategies.

Recent and Prospects of Synthesis and Application of Metal-Organic Frameworks (MOFs) in Water Treatment: A Review

Journal of Inorganic and Organometallic Polymers and Materials, Journal Year: 2024, Volume and Issue: 34(9), P. 3907 - 3930

Published: May 8, 2024

Abstract Wastewater treatment is designed to eradicate toxic pollutants emanating from the industrial effluent surface and underground water. The efficiency limitations of most existing water techniques such as coagulation/flocculation, photocatalysis, membrane technologies adsorption in remediation have been established. However, success reported for each these usually associated with environmental friendliness products applied. MOFs-based are one materials serving an alternative chemically synthesized products, their application has extensively but not systematically documented. In this review, authors endeavoured comprehensively provide insights into recent product synthesis different applications, especially treatment. key factors influencing MOFs, including choice metal ions, organic linkers, conditions, along latest developments scalable cost-effective fabrication discussed. routes, limitation performances adsorbent, photocatalyst additives removal elaborated. prospects large-scale production real applications critically reviewed study. Overall, a well-curated MOFs hereby generated best resources accessible through literature.

Meta-analysis to identify inhibition mechanisms for the effects of submerged plants on algae

Journal of Environmental Management, Journal Year: 2024, Volume and Issue: 355, P. 120480 - 120480

Published: March 1, 2024

Submerged plants inhibit algae through shading effects, nutrient competition, allelopathy, and combinations of these mechanisms. However, it is unclear which mechanism dominant, how the inhibition intensity results from traits plant algae. In this study, we performed meta-analysis to quantitatively identify dominant mechanisms, evaluate relationship between species functional submerged or algae, reveal influences external environmental factors. We found that allelopathy caused stronger than effect competition dominated combined Although leaf shapes influenced light availability, did not change degree suppression. Algal species, properties (toxic nontoxic) factors (e.g., lab/mesocosm experiments, co-/filtrate/extract culture, presence absence interspecific competition) potentially strength. Cyanobacteria Bacillariophyta were more strongly inhibited Chlorophyta, toxic non-toxic Cyanobacteria. Algae by was species-dependent.

Algae are a booming resource in the food industry due to their several health benefits. This study assesses impact of combined use selected macro- and microalgae improve nutritional profile labeling vegetable cream by introduction nutrition claims. As macroalgae, two Ascophyllum nodosum L., one natural (An) smoked (AnS), were for high iodine concentration flavor notes. A new strain Chlorella vulgaris, golden (CvG), was as microalgae, which is rich proteins has neutral sensorial (golden color mild flavor). In this study, creams compared. The control (CTRL) versus enriched with mixture macroalgae (CV-AN). Sensory, physicochemical, functional properties both evaluated. bioactivity assessed effect claim antioxidant antihypertensive properties. CV-AN showed significantly higher values (p < 0.05) protein content, value, activity, no significant differences > activity or sensory panel. incorporation these algae resulted better acceptability comparable control, offering source claims labeling.
