Summary: In order to solve the nitrate accumulation in recirculating aquaculture system (RAS), this study aimed to provide organic carbon source, denitrifying bacteria, and microenvironment for denitrification. Denitrifying capsules were prepared and their morphology, microbial community, and nitrogen removal efficiency were investigated. The denitrifying capsules had a porous structure and showed good adaptability to environmental conditions. They exhibited high nitrate removal rates even at low solid-to-liquid ratios or low temperatures. The denitrification process of the capsules followed a zero-order reaction and the denitrification rate was calculated to be 109.0 mg N/L-capsule dot h. The capsules showed a high nitrate removal rate until the litchi powder was exhausted.

Summary: This study experimentally synthesized bamboo fiber-reinforced biocomposites using bamboo fiber as filler and PBS as biodegradable polymer matrix. The research found that treated BF increased the tensile strength of the biocomposites, while higher BF content led to decreased elongation at break and increased Young's modulus. The biocomposites are suitable for packaging and indoor furniture parts.

Summary: The addition of exogenous AHLs and AHL-producing bacteria in biofilters treating gaseous toluene at a low temperature significantly improved the removal and mineralization efficiency of VOCs. These enhancements also improved the biofilm characteristics and biomass distribution, leading to improved performance of the biofilters.

Summary: This study explores the possibility of blending PBS and PCL with BSxCLy copolymers and systematically studies the crystallization behavior of the blends. The results show that the PBS/BS78CL22 blend exhibits good miscibility at high PBS content, while the PCL/BS15CL85 blend still displays partial miscibility at high PCL content. The BS46CL54 copolymer can crystallize in both PBS and PCL type crystals, depending on the polymeric matrix.

Summary: This study investigated the effects of two quorum sensing (QS) enhancement methods on the performance and biofilm of biofilters treating chlorobenzene. The results showed that adding exogenous AHLs had a more significant enhancing effect on biofilm, while AHLs producing bacteria helped improve bacterial community diversity.

Summary: PLLA and PBS are biodegradable, compostable, and biocompatible polymers that have complementary properties, making blending them an opportunity to exploit their favorable characteristics. However, research on the properties of PLLA/PBS blends has yielded contradictory results, creating complexity in their utilization.

Summary: This study investigates the application of a novel coordination-driven interface system in fiber-filled biopolymer composites. Results show that the iron ions (Fe3+) coordination with tannic acid (TA) interface enhances the interfacial compatibility and properties of the composites. The proposed interface formation method is cleaner, simpler, more energy-efficient, and effective, resulting in improved mechanical, thermal, crystallization, and hydrophobic performance of the biocomposites.

Summary: In this study, two nitrifying suspended growth bioreactor processes based on biofloc technology were investigated in recirculating aquaculture systems. The conversion of nitrifying bioreactor to denitrifying biofilter via adding carbohydrates was studied. The results showed that the dominant functional microbes in the nitrifying biofilters were ammonia-oxidizing bacteria, denitrifying bacteria, phosphorus/glycogen accumulating organisms, and nitrite-oxidizing bacteria. The addition of carbohydrates significantly improved the removal efficiency of nitrate and soluble reactive phosphate.

Summary: This study investigated the adsorption behavior of Pb(II) onto biodegradable poly(butylene succinate) (PBS) microplastics during its biodegradation. The results showed that the Pb(II) adsorption capacity of biofilm-colonized biodegraded-PBS microplastics was about 10 times higher than that of virgin PBS. Even after removing the biofilm, the biodegraded PBS still had high Pb(II) adsorption capacity due to the complexation of Pb(II) with the adhered extracellular polymeric substances (EPS).

Summary: This study investigates the effects of cellulose nanocrystals (CNC) from bamboo fiber on the properties of poly (lactic acid) (PLA)/poly (butylene succinate) (PBS) composites. The addition of CNC improves the thermal stability, tensile strength, and modulus of the composite, while reducing elongation at break.

Summary: This study developed a heterotrophic denitrification process using multistage anoxic and oxic biofilm (MAOB) to treat wastewater with high-strength nitrogen, sulfate, and low-strength organics. The recommended optimum conditions were a C/N ratio of 1.5 and a HRT of A (24 h)/O (12-24 h) to achieve > 90% of nitrogen and organics removal. The dominant denitrifying biofilm species in the tanks included Hyphomicrobium, Methylophaga, and Azoarcus, containing > 20% aerobic denitrifiers.

Summary: The addition of PVAc in PBS/PVAc blends was found to accelerate the crystallization rate of PBS but decrease the degree of crystallinity, improve the rheological properties of PBS, and enhance the stiffness, strength, and toughness simultaneously. This synergistic improvement in crystallization, rheological, and mechanical properties may be crucial for widening the application of PBS.

Summary: The study found that increasing bamboo powder content in the carrier reduces carbon availability and has a negative impact on nitrate removal efficiency, but improves ammonia removal rate. Different carrier formulations can affect microbial compositions, with high bamboo powder content decreasing relative abundance of denitrifiers and increasing that of nitrifiers.

Summary: The establishment of early-life gut microbiota is crucial for fish development and health. Rearing fish larvae in recirculating aquaculture systems (RAS) improves survival compared to flow-through systems (FTS), and dietary probiotic supplementation modulates gut bacterial composition, promoting beneficial bacteria presence.

Summary: The study revealed that in-situ produced biofloc significantly increased the prokaryotic diversity in tilapia gut, while dietary supplementation of processed biofloc only changed the relative abundance of minor prokaryotic taxa. The growth-promoting effect was only detected in the in-situ biofloc treatment, while dietary supplementation of processed biofloc had no effect on fish growth performance.

Summary: The study investigated the impact of early microbial colonisation on the gut microbiome and growth of Nile tilapia. Results showed that larvae cultured in biofloc system (BFS) exhibited better growth and different gut microbiome compared to flow-through system (FTS). Despite initial differences, long-term effects on gut microbiome composition, nutrient digestibility, and growth performance in later life were not observed, indicating that the legacy effect gradually disappeared during host development. However, BFS-reared fish exhibited increased gut microbial interactions, potentially benefiting gut health in juvenile Nile tilapia.
