Summary: This study investigates the effects of oleic acid (OA) and palmitic acid (PA) on both non-transformed human intestinal epithelial cells and colon carcinoma cells. Results show that OA and PA can alter the fluidity and structure of cell membranes, as well as the response to mechanical stimulation, suggesting a novel role for dietary fatty acids in regulating intestinal physiology.

Summary: Non-alcoholic fatty liver disease has a high prevalence and is related to the types and concentrations of fatty acids. Saturated fatty acids impair cell growth and lipid droplet formation, potentially leading to cell death, while oleic acid and mixtures containing oleic acid do not have adverse effects on cell growth and promote lipid droplet accumulation.

Summary: The form and fatty acid profile of lipid supplements have a significant impact on nutrient digestibility and cow performance. This study found that the form of fat supplements had a greater influence on digestibility than the fatty acid profile. The results suggest that form is an important factor to consider when selecting lipid supplements for cows.

Summary: The study found that feeding dairy cows with FA supplements containing C16:0 and cis-9 C18:1 during the immediate postpartum period resulted in better production and metabolic responses compared to the control group, with the effects carrying over into early lactation. Increasing cis-9 C18:1 content linearly increased dry matter intake but did not affect milk yield, while also reducing losses in body weight and body condition score.

Summary: This experiment found that feeding dairy cows fatty acid supplements containing palmitic and cis-9 C18:1 during the immediate postpartum period increased nutrient digestibility, energy intake, and milk energy output. Increasing dietary intake of cis-9 C18:1 can enhance energy intake, reduce markers of body fat mobilization, and improve energy balance during the immediate postpartum period.

Summary: Prenatal exposure to a high-fat diet increases hypothalamic neurogenesis events in embryos and programs the offspring to be prone to obesity. This study investigates the effects of oleic and palmitic acids, abundant in a high-fat diet, on the hypothalamic neuronal transcriptome and how these changes affect neurogenesis events. The results show that oleic acid stimulates proliferation and palmitic acid stimulates apoptosis in hypothalamic neurons, with both fatty acids impacting migration. Potential signaling pathways affected by these fatty acids are also uncovered.

Summary: This study investigated the performance of TADP and MADP fed with NaOH-microwave pretreated waste activated sludge. The results showed that MADP had lower methane production and reduction of organic matters compared to TADP, but had better dewatering performance for mesophilic sludge. Therefore, MADP is more suitable for the NaOH-MW pretreatment process.

Summary: This study demonstrated that iron-loaded biological activated carbon filter can effectively enhance the removal efficiency of low-concentration ammonia nitrogen wastewater at low temperature through improving surface properties to increase microbial quantity and metabolic activity, thus improving ammonia nitrogen removal rate. The presence of iron optimized the bacterial community structure and increased the abundances of psychrophilic bacteria and ammonia nitrogen removal bacteria on the surface of Fe-BAC, contributing to the enhanced biological nitrogen removal ability.

Summary: The co-digestion performance of mesophilic hollow fiber anaerobic membrane bioreactor (HF-AnMBR) treating high-solid lipids and food waste was studied for 180 days. The organic loading rate (OLR) was increased from 2.33 to 14.64 g-COD/L/d by increasing the lipids/FW ratio. The HF-AnMBR showed stable performance in terms of COD conversion efficiency, sludge growth rate, and concentrations of COD, proteins, and carbohydrates in permeate.

Summary: The long-term treatment of phosphorus-deficient wastewater using a one-stage partial nitrification-anammox (PNA) process may have negative effects on the growth of functional bacteria. A 650-day experiment was conducted using a lab-scale PNA system to study the impact of long-term phosphorus deficiency on nitrogen removal efficiency and sludge characteristics. It was found that phosphorus deficiency led to a decrease in nitrogen removal efficiency, high sludge volume index, and sludge bulking. The abundance of hzsA in flocs decreased significantly. However, the biofilm showed better resistance to phosphorus deficiency. After the addition of PO43--P, the nitrogen removal rate improved, and sludge bulking disappeared.

Summary: An anaerobic membrane bioreactor (AnMBR) was used to treat domestic sewage at 15 degrees C under different hydraulic retention time (HRT) conditions (6, 12, 16, and 24 h). The viability of microbial community in anaerobic digestion was assessed using Propidium monoazide (PMA)-PCR, which targeted microorganisms with intact cell membranes. The study found that a 6-hour HRT resulted in poor treatment performance, with low chemical oxygen demand removal efficiency and high mean trans-membrane pressure and flux. PMA-PCR combined with next-generation sequencing provided better identification of microbial changes compared to conventional 16S rRNA gene sequencing.

Summary: This study proposes high-salinity treatment as a novel strategy for inactivating nitrite-oxidising bacteria (NOB) and achieving stable partial nitritation (PN). The study found that NOB are more sensitive to high salinity than ammonia-oxidising bacteria (AOB), and increasing salinity inhibited nitrification. After high-salinity treatment, nitrite accumulation rate (NAR) was above 33% during nitrification. A novel process for achieving mainstream PN was proposed and evaluated based on the results.

Summary: Acorus calamus is recycled as an additional carbon source in microbial fuel cell-constructed wetlands for efficient nitrogen removal of low carbon wastewater. Alkali-pretreatment cleaves the benzene rings in dominant released organics, producing chemical oxygen demand of 164.5 mg per gram of A. calamus. Adding pretreated biomass in the anode of MFC-CW achieves maximum total nitrogen removal of 97.6% and power generation of 12.5 mW/m2.

Summary: This study used the innovative low-carbon nitrogen removal process of partial denitrification-anammox (PD-A) to simultaneously treat PPCCW and municipal wastewater pre-treated with 10 mg/L Fe3+. The results showed that the effluent had a total nitrogen concentration lower than 10 mg/L, with a removal efficiency of 79.67 +/- 3.48%. The dominant anammox genus was unclassified_f_Brocadiaceae, indicating the stability of the reactor. Hydrolytic acidifying bacteria SBR1031 and Bacillus increased substantially after feeding with actual wastewater, leading to increased removal efficiencies of organic material and nitrogen, suggesting a synergistic effect with PD-A bacteria. Finally, a novel wastewater treatment process that fully recovers carbon, phosphorus, and water was proposed.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.
