Special Issue Information

Dear Colleagues,

Harmful algal blooms, which are an unsolved major water environment problem worldwide, pose severe threats to aquatic ecosystem functions and human health. Although conventional methods of controlling blooms have achieved temporary and partial success, the increasing intensity and frequency of harmful blooms highlight the need for more effective solutions due to a warming climate and eutrophication. Thus, there is an urgent demand for technological innovation and improvement to realize more effective mitigation against harmful algal blooms and/or cyanotoxin release. Besides algicidal technologies, the reasonable utilization of algal biomass is considered a promising way to carry out bloom mitigation and resource recycling. Comprehensive algicidal and recycling mechanisms are also global concerns. Therefore, we are launching this Special Issue which aims to integrate novel techniques and materials, and/or uncover underlying mechanisms, with the ultimate goal of inspiring innovative scientific solutions in this field.

For this Special Issue, we are specifically seeking manuscripts that involve novel techniques and materials for bloom mitigation, including, but not limited to: (i) effects on algal populations and/or communities, e.g., their control/prevention/remediation effectiveness, eco-compatibility, and sustainability; (ii) synergistic effects with various factors, e.g., current climate factors and emerging pollutants; (iii) comprehensive mechanisms, e.g., emerging bio-indicators and omics analysis. We welcome manuscripts in the form of original research articles, reviews, short communications, perspectives, and commentaries on the aforementioned topics and domains.

This study investigates the decomposition process of algal blooms (ABs) in eutrophic lakes and its impact on the labile endogenous nitrogen (N) cycle. In situ techniques such as diffusive gradients in thin films (DGT) and high-resolution dialysis (HR-Peeper) were employed to decipher the vertical distribution of N fractions within the sediment–water interface (SWI) in Taihu, China. Additionally, an annular flume was used to simulate regional differences in lake conditions and understand labile nitrogen transformation during AB decomposition. This study reveals that the NH4+-N fraction exuded from algae is subsequently converted into NO3-N and NO2-N through nitrification, resulting in a significant increase in the concentrations of NO3−-N and NO2−-N at the SWI. The decomposition of algae also induces a significant increase in dissolved organic matter (DOM) concentration, referring to humic acid and humus-like components; a seven-millimeter decrease in dissolved oxygen (DO) penetration depth; as well as a significant decrease in the pH value near the SWI, which consequently promotes denitrification processes in the sediment. Moreover, the decomposition process influences nitrogen distribution patterns and the role conversion of sediments between a “source” and a “sink” of nitrogen. This investigation provides evidence on the migration and/or transformation of N fractions and offers insights into the dynamic processes across the SWI in eutrophic lakes. Full article

The outbreak of algae in freshwater bodies poses an important threat to aquatic ecosystems, making finding an effective method for controlling algal blooms imperative. Numerous key factors influence algal bloom outbreaks, with nutrient levels in the water body being the decisive factor. Current research regarding the effect of nutrient levels on algal growth shows that phosphorus is a nutrient that influences algal blooms. Herein, we propose the concept of a modified Monod model for the relationship between algal specific growth rate and phosphorus concentration. Through this improved Monod model, we inferred that the phosphorus concentration at a specific growth rate of zero is the lower threshold of phosphorus concentration that limits algal growth and can effectively control algal outbreaks. This lower threshold is denoted as S′. On the basis of this concept, we designed algal growth experiments. Our results provided an equation that effectively describes the relationship between algal growth and nutrient concentration. When three algal species grow under phosphorus-limited conditions, the corresponding phosphorus concentrations at which they maintain a growth rate of 0 are 0.0565, 0.0386, and 0.0205 mg/L as reflected by the following order of their S′ values: Microcystis wesenbergii S′ < Microcystis aeruginosa S′ < Chlorella vulgaris S′. Furthermore, with the increase in phosphorus concentration, the growth of M. aeruginosa becomes faster than that of M. wesenbergii and C. vulgaris. Consequently, M. aeruginosa becomes the dominant population in the water, leading to its predominance in algal blooms. This situation explains the common occurrence of cyanobacterial blooms. Our findings provide a theoretical basis for regulating the concentration of phosphorus to control algal outbreaks. Therefore, our study is of great importance for controlling the eutrophication of water bodies. Full article
