Summary: This study found that using a combination of two or more conductive materials (CMs) can improve the production in a two-stage fermentation process (TSFP). Magnetite nanoparticle (MNP) played a crucial role in enhancing H2 production in the first stage, while powdered activated carbon (PAC) contributed to higher CH4 production in the second stage.

Summary: Hydrogen production from waste-activated sludge anaerobic fermentation is an effective method of resource recovery. However, the presence of diclofenac, a widely used anti-inflammatory drug, inhibits hydrogen production by binding to the active sites of hydrogenase, which leads to the inhibition of acetogenesis and acidogenesis processes that are responsible for hydrogen production.

Summary: The study found that the maximum hydrogen yield from waste activated sludge increased with the concentration of Rhamnolipid (RL) up to 0.10 g/g TSS. However, further enhancement to 0.12 g/g TSS slightly reduced the hydrogen production. The research suggested that RL facilitated the solubilization of waste activated sludge and improved the proportion of biodegradable substances available for hydrogen production.

Summary: The study demonstrates that rhamnolipid (RL) pretreatment has a promoting effect on methane production in two-phase anaerobic digestion of waste activated sludge, although methane production may be inhibited in the presence of RL during the acidogenic phase. Further analysis shows that the addition of RL can increase methane production throughout the entire two-phase anaerobic digestion process.

Summary: Temperature and voltage are critical factors in microbial electrolysis cells (MECs) for antibiotic removal. It was found that a thermophilic MEC operating at 55 degrees C and 0.8 V achieved the highest antibiotic removal efficiency of 58.7%. This was attributed to increased bioelectrochemical and microbial activity, facilitating solid-liquid migration and having a significant positive correlation with antibiotic removal. Geobacter and Thermincola were dominant bacteria in the anode biofilms of mesophilic and thermophilic MECs, respectively.

Summary: The study investigates the performance of using the anaerobic ammonia oxidation (anammox) biofilm process to treat iron-containing industrial wastewater with a low carbon-nitrogen ratio. It is found that low levels of Fe (III) do not affect the performance of anammox nitrogen removal, but high concentrations have a negative effect. The inhibitory effect can be reversed by introducing the ferric ion complex EDTA center dot 2Na into the system.

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.
