Summary: The establishment of a multistage anaerobic hythane reactor (MAHR) that integrates biohythane and biomethane production into a single reactor demonstrates promising potential for simultaneously producing hythane and methane. The study shows that stable hythane and methane production can be achieved in MAHR without inoculum preselection, and MAHR without inoculum preselection suggests a higher methane production rate and resistance to organic loading shock. The microbial community dynamics and stage separation mechanisms are also explored in this study.

Summary: The development of starch-based films has shown the potential for creating transparent, non-toxic, biodegradable materials with good gas barrier properties. However, the use of starch in packaging should be avoided due to world hunger-related problems. Utilizing residual starches can reduce production costs and promote the development of innovative biomaterials. The addition of gelatinized starch from agro-industrial residues in bioplastic production has shown a decrease in tensile strength and elastic modulus values, but no significant impact on elongation percentage values.

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: 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: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
