Lysosome-associated membrane glycoproteins (LAMPs), including lysosomal membrane protein 1 (Lamp1) and lysosomal membrane protein 2 (Lamp2), are involved in phagocytosis, chaperone-mediated autophagy (CMA), and other pathways that interact with lysosomal activity. However, the role of Lamp2 in teleosts has not been clarified. In this study, we investigated the functions of genes during infection.

Partial Nitritation/Anammox (PN/A) can achieve green, economical, and efficient biological nitrogen removal; however, the PN process contributes significantly to nitrous oxide (NO, the third most important greenhouse gas) emissions. Balancing the stability of PN systems while reducing NO emissions, particularly under varying salinity conditions, is a key challenge in applying PN/A for high-salinity and high-ammonia wastewater treatment. This study explored the long-term effects of salinity on PN performance and NO emissions in PN systems treating high-ammonia wastewater.

Solid carbon-driven biofilm system can provide sufficient carbon source for denitrification, while its counter-diffusional structure could inevitably induce the delayed carbon-nitrogen contact and electron transport, further affecting carbon footprints mainly contributed by nitrous oxide (NO) at wastewater treatment plants (WWTPs). However, the detailed understanding of NO dynamics during solid-phase denitrification (SPD) has not been disclosed. In this work, a fixed bed bioreactor driven by polycaprolactone (PCL) was constructed and operated over 180 days, achieving 97 %-99 % of total nitrogen (TN) removal efficiency.

Article Synopsis
  • Widespread PET microplastics in wastewater treatment plants impact nitrous oxide (NO) turnover, affecting production and consumption processes.
  • The study assesses the effects of two sizes of PET MPs (0.1 mm and 0.5 mm) on NO dynamics in aerobic granular sludge systems, revealing that 0.1 mm PET MPs significantly inhibit denitrification processes.
  • Results show that 0.1 mm PET MPs promote NO production by disrupting microbial activities and electron transfer, ultimately reducing the system's NO-sink capability and hindering efforts toward carbon neutrality.

  • Sulfidogenic and methanogenic processes in sewer management create issues like organic losses that are often overlooked, as current methods focus mainly on chemical dosing for control.
  • In a laboratory study, the organic silicon quaternary ammonium salt (QSA) was used in sewer reactors, suppressing sulfidogenic activity recovery and maintaining low methanogenic activity levels after treatment.
  • The study found that QSA attached to biofilms through electrostatic attraction, improving control efficiency and altering microbial communities, with preliminary tests showing enhanced biodegradability of effluent, supporting its use in wastewater management.

Japanese flounder is usually gonochoristic, with gonads that are either testes or ovaries. Here, we report an unusual case of hermaphroditism in Japanese flounder captured from the Bohai Sea. In the intersex flounder, the membrane of the upper ovary was closely connected to the abdominal muscles and internal organs, and the eggs filled the entire abdomen.

Since the advent of germ cell transplantation (GCT), it has been widely used in shortening the fish breeding cycle, sex-controlled breeding and the protection of rare and endangered fish. In this study, the effectiveness of female sterile recipient preparation and donor stem cell isolation and purification were comprehensively evaluated for spermatogonial stem cell transplantation (SSCT) in . The best way to prepare sterile recipients was found to be giving three-year-old fish four intraovarian injections of busulfan (20 mg/kg body weight) combined with exposure to a high temperature (28 °C) after the spawning season compared with the two other ways, which induced apoptosis of most of the endogenous germ cells, resulting in shrinkage of the spawning plate and enlargement of the ovarian lumen.

Article Synopsis
  • This study compares two electrochemical methods for controlling sulfide in sewer networks, highlighting the superiority of the two-electron oxygen reduction reaction (2e-ORR) over hydrogen evolution reaction (HER).
  • The use of a gas diffusion electrode (GDE) produced a stable concentration of hypochlorite (HO₂⁻) and maintained dissolved oxygen levels, leading to a significant increase in sewage pH and a 99.93% reduction in sulfides.
  • Seawater treated with cation exchange resin (CER) was found to be a promising alternative to freshwater for electrolyte use in these processes.

The wide utilization of poly dimethyl diallyl ammonium chloride (polyDADMAC) in industrial conditions leads to its accumulation in waste activated sludge (WAS), thereby affecting subsequent WAS treatment processes. This work investigated the interaction between polyDADMAC and WAS components from the perspective of anaerobic digestion (AD) performance and anaerobes adaptability variation. The results showed that polyDADMAC decreased the content of biodegradable organic substrates (i.

The production of short-chain fatty acids (SCFAs) through anaerobic fermentation of waste activated sludge (WAS) is commonly constrained by limited substrate availability, particularly for WAS with low organic content. Combining the hydrocyclone (HC) selection with alkali-thermal (AT) pretreatment is a promising solution to address this limitation. The results indicated that HC selection modified the sludge properties by enhancing the ratio of mixed liquid volatile suspended solids (MLVSS)/mixed liquid suspended solids (MLSS) by 19.

Freshwater ecosystems, such as urban lake sediments, have been identified as important sources of greenhouse gases (GHGs) to the atmosphere, as well as persistent sinks for ubiquitous microplastics due to the high population density and frequent anthropogenic activity. The potential impacts of microplastics on GHG production, however, remain underexplored. In this study, four types of common biodegradable microplastics (BMPs) versus four conventional non-biodegradable microplastics (NBMPs) were artificially exposed to urban lake sediments to investigate the responses of nitrous oxide (NO) and methane (CH) production, and make a comparison regarding how the biodegradability of microplastics affected GHG emissions.

Electrochemically in-situ generation of oxygen and caustic soda is promising for sulfide management while suffers from scaling, poor inactivating capacity, hydrogen release and ammonia escape. In this study, the four-compartment electrochemical cell efficiently captured oxygen molecules from the air chamber to produce HO without generating toxic by-products. Meanwhile, the catalyst layer surface of PTFE/CB-GDE maintained a relatively balanced gas-liquid micro-environment, enabling the formation of enduring solid-liquid-gas interfaces for efficient HO electrosynthesis.

Flow cytometry (FC) is routinely used for hematological disease diagnosis and monitoring. Advancement in this technology allows us to measure an increasing number of markers simultaneously, generating complex high-dimensional datasets. However, current analytic software and methods rely on experienced analysts to perform labor-intensive manual inspection and interpretation on a series of 2-dimensional plots via a complex, sequential gating process.

Article Synopsis
  • - The study focuses on the ube3a gene in Japanese flounder, a member of the E3 ubiquitin ligase family, and its potential role in fighting off Chinook salmon bafnivirus (CSBV).
  • - Researchers cloned the ube3a gene, noting its high similarity (94%) to the Atlantic halibut and found that this gene is most expressed in the fin, gills, and skin of the fish.
  • - In experiments, overexpressing ube3a led to a reduced viral load in infected gill cells, while blocking its function increased the viral load, indicating that ube3a likely has a significant antiviral effect through the ubiquitination pathway.
