Description of Hyphococcus formosus sp. nov. and Hyphococcus lacteus sp. nov., isolated from coastal sediment, and reclassification of Marinicaulis flavus as Hyphococcus luteus nom. nov. and Marinicaulis aureus as Hyphococcus aureus comb. nov.

During a study on sediment bacterial diversity in coastal China, three bacterial strains, DH-69, EH-24, and ECK-19, were isolated from coastal sediments off Xiaoshi Island, Weihai. These strains were Gram-staining-negative, aerobic, and coccoid to rod-shaped with prosthecae and flagella. Comparison of the 16S rRNA gene showed that they shared the highest identity values with Hyphococcus flavus MCCC 1K03223 (96.

Describing five new strains in the family Woeseiaceae and emended description of the order Woeseiales with genomic features related to environmental adaptation.

The family Woeseiaceae, also known as the JTB255 bacterial group, are ubiquitous and abundant core members of microbial communities in marine surface sediments. However, to date, only one Woeseiaceae strain isolated from marine sediments has been described, and the phylogeny and environmental adaptation mechanisms of this group have been little explored. Here, we isolated five novel Woeseiaceae strains from the marine solar saltern in Weihai, China.

Description of the first marine-isolated member of the under-represented phylum , and the environmental distribution and ecogenomics of ord. nov.

The phylum is widespread but rarely cultured and, in fact, there are only six described species isolated from soil, freshwater, and wastewater treatment. However, no isolates of from marine environment have been described; thus, little is known about the physiology and metabolism of members of the marine lineages. In this study, four novel facultatively anaerobic bacterial strains belonging to were isolated from marine sediments collected from Xiaoshi Island in Weihai, China, using an aerobic enrichment method.

Study on the physiological responses and tolerance mechanisms to subchronic carbonate alkalinity exposure in the gills of Paramisgurnus dabryanus.

Given the reduction of freshwater resources, saline-alkaline aquaculture has emerged as an effective approach to expand the fishery's accessible space. High carbonate alkalinity (CA) is a major stressor for aquatic organisms in saline-alkaline environments. Paramisgurnus dabryanus is a potential species for culture in saline-alkaline water, making it an ideal model for investigating the physiological responses and tolerance mechanisms to CA exposure in freshwater fishes.

Unprecedented NO production by nitrate-ammonifying with distinctive NO isotopocule signatures.

Dissimilatory nitrate reduction to ammonium (DNRA), driven by nitrate-ammonifying bacteria, is an increasingly appreciated nitrogen-cycling pathway in terrestrial ecosystems. This process reportedly generates nitrous oxide (NO), a strong greenhouse gas with ozone-depleting effects. However, it remains poorly understood how NO is produced by environmental nitrate-ammonifiers and how to identify DNRA-derived NO.

The Predatory Properties of Bradymonabacteria, the Representative of Facultative Prey-Dependent Predators.

Bradymonabacteria, as the representative of the facultative prey-dependent predators, were re-classified from the preceding into the phylum and proposed as a novel class named . However, it was ambiguous whether their predatory pattern and properties were similar to those of the other myxobacterial predators. Therefore, the physiologic features were compared to determine the similarities and differences during the process of group attack and kin discrimination.

infection delays neutrophil apoptosis and exacerbates inflammatory response.

Understanding molecular mechanisms of ()-induced inflammation is important for developing new therapeutic strategies for gastrointestinal diseases. We designed an -neutrophil infection model and explored the effects of infection on neutrophils. infected neutrophils showed a low level of apoptosis.

Preliminary study of BF/C2 on immune mechanism of grass carp against GCRV infection.

BF/C2 is a crucial molecule in the coagulation complement cascade pathway and plays a significant role in the immune response of grass carp through the classical, alternative, and lectin pathways during GCRV infection. In vivo experiments demonstrated that the mRNA expression levels of BF/C2 (A, B) in grass carp positively correlated with GCRV viral replication at various stages of infection. Excessive inflammation leading to death coincided with peak levels of BF/C2 (A, B) mRNA expression and GCRV viral replication.

The role of MASP1 in the complement system and expression characteristics in response to GCRV infection in grass carp.

The grass carp (Ctenopharyngodon idella) constitutes a significant economic resource within the aquaculture sector of our nation, yet it has been chronically afflicted by the Grass Carp Reovirus (GCRV) disease. The complement system, a vital component of fish's innate immunity, plays a crucial role in combating viral infections. This research investigates the potential role of MASP1, a key molecule in the lectin pathway of the complement system, in the GCRV infection in grass carp.

Cultivating the uncultured: Harnessing the "sandwich agar plate" approach to isolate heme-dependent bacteria from marine sediment.

In the classical microbial isolation technique, the isolation process inevitably destroys all microbial interactions and thus makes it difficult to culture the many microorganisms that rely on these interactions for survival. In this study, we designed a simple coculture technique named the "sandwich agar plate method," which maintains microbial interactions throughout the isolation and pure culture processes. The total yield of uncultured species in sandwich agar plates based on eight helper strains was almost 10-fold that of the control group.

Dietary resveratrol improves the flesh quality of Siberian sturgeon (Acipenser baerii) by enhancing myofiber growth, nutrient accumulation and antioxidant capacity.

Background: In aquaculture, sturgeons are generally maintained in the confined spaces, which not only hinders sturgeon movement, but also threatens their flesh quality that seriously concerned by aquaculture industry. As a typical antioxidant, resveratrol can improve the flesh quality of livestock and poultry. However, the mechanism of resveratrol's effect on the muscle of Siberian sturgeon is still unclear.

Direct Degradation of Fresh and Dried Macroalgae by B2Z047.

Marine macroalgae are increasingly recognized for their significant biological and economic potential. The key to unlocking this potential lies in the efficient degradation of all carbohydrates from the macroalgae biomass. However, a variety of polysaccharides (alginate, cellulose, fucoidan, and laminarin), are difficult to degrade simultaneously in a short time.
