Summary: This study isolated and identified two bacterial strains capable of completely degrading malathion within 36 hours from deep-sea sediment. These strains have abundant carboxylesterases (CEs) genes and degrade malathion through the pathway from malathion monocarboxylic acid to malathion dicarboxylic acid.

Summary: This study successfully overexpressed the AzK gene in Escherichia coli for the efficient degradation of Remazol Red-R and Acid-Blue 29 dyes. Optimal conditions were determined as 1.5% inoculum size, 0.5 mM IPTG concentration, and 6 hours incubation time. The crude extract achieved 76% and 74% decolorization of RRR and AB-29, while the purified enzyme achieved 94% and 93% decolorization within 0.3 hours. Kinetic analysis revealed the enzymatic characteristics and HPLC and GC-MS analyses confirmed the effective biotransformation of dyes into less toxic metabolites. This study highlights the potential of recombinant azoreductase for the degradation of textile azo dyes.

Summary: Sea cucumbers and sea urchins are promising aquaculture candidates due to their high market value and low-trophic nature. The study demonstrated successful integrated aquaculture between these organisms, with a 20% fish meal supplement being the most efficient food source. The aquaculture model reduced waste effectively and provided added value in the form of sea cucumber biomass.

Summary: Micropollutants (MPs) are a wide range of biological disruptors that can be toxic to wildlife and humans at very low concentrations (<1 μg/L). A systematic review of literature revealed that MPs have been detected globally, with higher concentrations in the Northern Hemisphere. MPs are more frequently found in depths up to 3000 m, but can extend deeper than 10,000 m.

Summary: Observations are crucial in exploring and understanding the ocean. The Red Sea Decade Expedition reported three observations of Firoloida desmarestia, a shell-less mollusk, for the first time in the Red Sea, indicating a global distribution for this species. The observations suggest a depth range expansion and raise questions about the species' behavior and vertical migrations. A literature search was conducted to understand the global distribution and ecological significance of this species.

Summary: Authigenic processes in aqueous environments, such as mineral precipitation, can lead to turbidity that affects the natural environment and industrial processes. Monitoring turbidity is crucial for determining water quality and tracking industrial processes. However, the dynamic nature of turbidity, especially in relation to processes like gypsum precipitation, requires further study. The proposed Red Sea-Dead Sea project aims to slow down the decline in the Dead Sea's water level by desalinating seawater and conveying reject brine, potentially leading to gypsum precipitation and increased turbidity. The study highlights the importance of monitoring and studying authigenic processes in large-scale natural systems for potential impacts on water bodies like the Dead Sea.

Summary: Synthetic dye bioremediation is important due to their toxicity and large quantities discharged into water bodies. Ligninolytic enzyme treatment, particularly laccase, has been shown to be cost-effective and achieve high decolorization levels. Immobilization of concentrated laccase extract can improve stability but may decrease dye decolorization efficiency.

Summary: This study aimed to explore the taxonomic and functional profiles of Arabian Sea sediments through whole metagenome sequencing using Nanopore technology. The results revealed Proteobacteria as the dominant phylum in the sediment metagenome, followed by Bacteroidetes and Actinobacteria. Additionally, the study generated Metagenome Assembled Genomes (MAGs) from long-read sequence dataset, with major representations from the genera Marinobacter, Kangiella, and Porticoccus. The analysis also identified a high representation of pollutant-degrading enzymes involved in hydrocarbon, plastic, and dye degradation.

Summary: This study reveals a significant presence of microplastics in the surface water, sediments, and fishes of the Mediterranean and Red seas in Egypt. Higher microplastic abundance was observed at the Ras Gharib station in the Red sea and Damietta and Port Said stations in the Mediterranean sea. Additionally, the study emphasizes the need for measures to reduce plastic influx into marine settings to protect fisheries and marine ecosystems.

Summary: Marine heat waves can have catastrophic consequences for the socio-environmental system, especially in the Red Sea. Analysis of sea surface temperature variability and trends in the Red Sea from 1982-2019 shows an average warming rate of 0.342 +/- 0.047 degrees C/decade, with increases in MHW frequency and duration over the past two decades. The strong correlation between MHW frequency and annual mean SST indicates a potential link between warming temperatures and more frequent marine heat waves in the Red Sea.

Summary: The study evaluated the effects of solar radiation on the ecophysiology and biochemical responses of the brown macroalga Macrocystis pyrifera in southern Chile using a mesocosm approach. Different light conditions did not affect nutrient concentration and temperature, but photosynthetic activity varied in different parts of the plant at different depths. Solar radiation influenced the productivity and phenol content of the algae, with the highest productivity observed in thalli exposed to solar irradiance in the canopy zone.

Summary: Seaweed farming has been promoted as a climate solution, but the carbon sink function is diminished due to consumption and alternative applications. Seaweeds can reduce greenhouse gas emissions through carbon offset and potentially through reducing enteric methane emissions from ruminants and bioenergy production. However, further research is needed to understand seaweeds' carbon cycling and contributions.

Summary: This study successfully valorized the red alga Gracilaria chilensis by sequentially extracting phycobiliproteins (PBPs) and agar. The extracted PBPs (R-phycoerythrin and R-phycocyanin) were recovered and purified, while agar with similar physical properties as directly extracted agar from G. chilensis was obtained. The agar obtained after PBPs extraction showed no inhibitory effects on microbial growth and allowed effective nucleic acid separation.

Summary: Gracilaria aquaculture is a rapidly growing industry that contributes significantly to the global seaweed supply chain. Despite the importance of biosecurity, it is often overlooked. China and other Asian countries dominate global gracilarioids aquaculture, but there are gaps in their national policies and regulations. The paper suggests implementing biosecurity management strategies and discusses the impending biosecurity measures in emerging countries in this industry.

Summary: In this study, algal-based biochar was transformed into carbon nanotubes by microwave irradiation. Different species of algae were pyrolyzed to obtain biochar, which served as precursors for CNT growth with ferrocene as the catalyst. The characteristics of the synthesized CNTs varied depending on the biochar source, such as the carbon content and mineral ash content. Low catalyst concentration was found to be sufficient for growth promotion, and microwave heating conditions affected the optical properties of CNTs.

Summary: The distribution and productivity of seaweeds are influenced by changes in temperature and inorganic nitrogen availability. The effect of the nitrate: ammonium ratio on physiological traits and gametophyte development of Macrocystis was investigated, showing that NH4+ led to negative NO3- uptake rates and reduced growth rates. Different developmental stages and physiological traits may have varying thermal tolerance windows.

Summary: The recent research describes the actions, interactions, and behavior types exhibited by fish in captivity. The gray mullet's behavior was categorized into four patterns of activity and two feeding variables. The study suggests that the gray mullet is diurnal with gradual locomotion and exhibits cooperative behavior, making it suitable for commercial culture.
