Summary: In this study, an algicidal bacterium named Shewanella Y1 was isolated and its mechanism of action against A. pacificum was investigated. The results showed that Y1 inhibited the photosynthetic activities of A. pacificum, leading to the overproduction of ROS and oxidative damage, ultimately inducing cell death. These findings provide a better understanding of the biological basis of complex algicidal bacterium-harmful algae interactions and offer a potential bacterial agent for controlling harmful algal blooms.

Summary: This study evaluates the mitigating effects of seaweeds on the toxicity of Margalefidinium polykrikoides towards early life stage fish. The results show that live seaweeds, particularly Ulva spp., significantly extend fish survival and completely mitigate fish mortality. The antioxidant properties of seaweeds are responsible for the protective effects.

Summary: The study revealed that Cochlodinium geminatum produces allelopathic compounds that have significant inhibitory effects on Akashiwo sanguinea, with time-dependent reduction and synergistic effects. These compounds also showed competitive advantages by inhibiting co-occurring phytoplankton and promoting population growth.

Summary: The study investigated the estuarine movement patterns of Mugil cephalus in response to Harmful algal blooms in a eutrophied estuary in South Africa. The results showed that the fish mainly occupied the upper mesohaline to lower oligohaline zones and avoided the bloom maxima areas. This is the first study to document small-scale intra-estuary movements of a mugilid worldwide and to suggest avoidance behavior of estuarine fishes in response to HABs.

Summary: In this study, the biosorption capacity of microalgae Prorocentrum triestinum strain AD1 for cadmium removal was investigated. The maximum adsorption capacity was found to be 0.0196 mmol/g, with an optimum pH of 5 and an effective contact time of 3 hours. Furthermore, HCl at a concentration of 0.01 M was identified as an efficient desorbent for cadmium recovery.

Summary: In this study, a novel anti-MC-LR/MC-LR/cysteamine-coated screen-printed carbon electrode biosensor was developed for rapid detection of microcystins in water. The biosensor showed excellent performance, with a linear working range and low limit of detection. It also demonstrated minimal interference from other common microcystins and coexisting ions in water. The biosensor offers an innovative and easy-to-use solution for in situ and low-cost detection, making it essential for smart environmental management systems.

Summary: This review summarizes the temporal and geographical distribution of Noctiluca scintillans harmful algal blooms (HABs) in China, as well as its position in the plankton structure. The blooms occur frequently in Chinese coastal regions from April to June, with short-term and small coverage being the primary type. Recent studies have reported an increasing abundance and dominance of Noctiluca scintillans in Chinese coastal waters, with multiple environmental factors playing a role. The mechanisms responsible for its dominance and HAB outbreaks require further study.

Summary: This review article discusses the complex and dynamic interactions between bacteria and phytoplankton in aquatic ecosystems, with a focus on algicidal interactions. Bacteria can control algal growth through physical association or the production of algicidal compounds. The article highlights the specificity of bacterial control, mechanisms for activity, and chemical and biochemical analysis of these interactions. It also reviews the development of environmentally friendly or sustainable methods using algicidal bacteria or compounds derived from bacteria to control harmful algal blooms. The article concludes with potential avenues for future research and the further development and application of bacterial algicides.

Summary: Harmful algal blooms, caused by dinoflagellates and cyanobacteria, have significant impacts on human, animal, and ecosystem health, primarily through the production of algal toxins that bioaccumulate in filter-feeding organisms and transfer through the food web. New science and interdisciplinary assessment are necessary to ensure a continued increasing supply of aquaculture foodstuffs for future generations in the face of expected more frequent and intense HAB outbreaks.

Summary: In this study, a highly efficient algicidal bacterium LD-B6 was isolated from the coastal waters of Lianyungang, China, which showed strong algicidal activity against the harmful algal species Noctiluca scintillans. The bacterium was found to lyse algal cells by secreting stable extracellular compounds, and it exhibited algicidal effects against multiple algal species. These findings are important for the prevention and control of Noctiluca scintillans blooms.
