Article Synopsis
- Algae are crucial for carbon dioxide exchange between water and the atmosphere, but the impact of different types on carbon use is not well understood.
- The study found that shifts in dominant algae, particularly between Cyanobacteria and Chlorophyta, significantly affected carbon dioxide levels and that Chlorophyta had a much greater impact on carbon sinks.
- The research indicates that promoting Chlorophyta growth could effectively enhance carbon dioxide absorption and lower emissions compared to Cyanobacteria.
Effect of the N-hexanoyl-L-homoserine Lactone on the Carbon Fixation Capacity of the Algae-Bacteria System.
Int J Environ Res Public Health
March 2023
Algae-bacteria systems are used widely in wastewater treatment. N-hexanoyl-L-homoserine lactone (AHL) plays an important role in algal-bacteria communication. However, little study has been conducted on the ability of AHLs to regulate algal metabolism and the carbon fixation ability, especially in algae-bacteria system.

However, in a highly dynamic land-water reservoir, the microbial metabolic changes brought on by the changes of water nutrients following rainfall are not clearly documented. The study selected the Three Gorges Reservoir (TGR) backwater region during algal bloom seasons as the study area and time, and used the Biolog-EcoPlates technique to examine the heterotrophic metabolism conditions of the water before and after rain.

Article Synopsis
- The paper explores user identification across social media using a method called MSF-UI, which combines various user features like display name, network connections, and content.
- This approach employs a multi-module calculation to assess similarities among these features and utilizes the bidirectional stable marriage matching algorithm for better identification accuracy.
- Experimental results demonstrate that MSF-UI outperforms traditional methods by enhancing user identification effectiveness in terms of precision, recall, and overall evaluation metrics.
To understand the runoff pollution characteristics of the typical purple soil small watershed in the Three Gorges Reservoir (TGR), the rainfall-runoff duration under typical land use types of the Xinzheng watershed and the nitrogen (N) and phosphorus (P) concentrations in the outlet runoff of each catchment were dynamically monitored, and the loss rule of N and P in the rainfall runoff in the small watershed in the TGR was investigated and analyzed. The results showed that the losses of runoff N and P were 13.69 kg·(hm·a) and 1.
