Lake sediments connection to the biogeochemical cycling of phosphorus (P) and carbon (C) influences streamwater quality. However, it is unclear whether how type sediment controls P C in water. Here, adsorption behavior montmorillonite (Mt) with different interlayer cations (Na+, Ca2+, or Fe3+) on dissolved organic matter (DOM) was investigated understand role Mt regulating carbon-to-phosphate (OC/P) ratio within freshwater systems. The capacity Fe–Mt for 3.2-fold higher than that Ca–Mt, while 1/3 lower DOM. This dissimilarity led an increased OC/P Fe–Mt-dominated water a decreased Ca–Mt-dominated Moreover, situ atomic force microscope high-resolution mass spectrometry revealed molecular fractionation mechanisms adsorptive processes. It observed DOM inhibited nucleation crystallization processes surface, affected binding energy through competitive adsorption, thereby governing interfacial P/DOM dynamics substrates at level. These findings have important implications quality management, by highlighting clay minerals as nutrient sinks providing new strategies controlling

Phosphorus (P) is a fundamental element for life, playing an integral role in cellular metabolism including energy transfer, nucleic acid synthesis, and membrane structure. This nutrient critical to the physiological ecology all photosynthetic organisms eukaryotic microalgae cyanobacteria. The review, here presented, delves into intricate mechanisms governing phosphorus acquisition from environment, its utilization plant metabolism, regulation these microorganisms. Furthermore, it comprehensively explores strategies employed by cope with limitation, such as activation of high-affinity phosphate transporters synthesis storage compounds. On other hand, ability consume abundant makes exploitable environmental remediation processes. knowledge synthesized this review contributes broader understanding microalgal physiology, offering insights ecological biotechnological implications assimilation

Human Activity Coupled With Climate Change Strengthens the Role of Lakes as an Active Pipe of Dissolved Organic Matter

Earth s Future, Год журнала: 2023, Номер 11(9)

Abstract Dissolved organic matter (DOM) composition in lakes is controlled by multiple environmental drivers, but the relative importance of various drivers remains poorly understood at continental scale. Here, we established a model resolving possible influencing pathways climate, land cover, societal development, and water retention time on quantity quality chromophoric DOM (CDOM) from 182 spanning across strong climatic economic gradients China. Our results indicate that cover development both exhibit positive direct effects lake CDOM quantity, highlighting significant role well‐vegetated soils anthropogenic activities as sources Climate has two opposite effects—a warming wet climate facilitates soil OM production export, while it also enhances in‐lake transformation. Three proxies are proposed indicators magnitude biogeochemical different ecoclimatic zones, including fluorescent DOM/DOC indicating activity, percentages degraded component solar irradiation, percent tyrosine‐like reflecting processing within watershed lake. Collectively, our findings change rapid will result increased loadings terrestrial into drive higher rates within‐lake DOM. Consequently, play more important an “active pipe” mediating flux transformation carbon, intensifying coupling between aquatic carbon cycles
