Summary: The performance of the upflow anaerobic sludge blanket (UASB) reactor for stable H2 production from starchy wastewater supplemented with groundnut de-oiled cake using mixed consortia was investigated in this study. Limited research on H2 production for UASB reactor has been reported. The operation of the UASB reactor was divided into start-up period and production period, with different hydraulic retention times (HRT) examined for H2 production. The maximum H2 production rate of 12.3 L L-1 d-1 was observed at 3 h HRT. Physicochemical characteristics of the granular sludge were studied, and advanced bio-kinetic models were implemented to analyze the substrate consumption on hydrogen production.

Summary: This study aimed to enhance the methanogenic activity of distillery wastewater with high potassium (K) content using a mesophilic three-stage upflow anaerobic sludge blanket (UASB). The three-stage UASB could not function properly at a chemical oxygen demand (COD) loading rate greater than 3 kg/m3d due to potassium toxicity. However, by diluting the wastewater to reach moderate K toxicity, the three-stage UASB was able to effectively function at high COD loading rates due to the development of adapted anaerobe communities.

Summary: Autogenerative high-pressure digestion has the advantage of producing CH4-rich biogas directly. In this study, a continuous operation of upflow anaerobic sludge blanket reactor (UASB) was performed with pressure gradually increasing from 1 to 8 bar. The CH4 content in the biogas gradually increased with increasing pressure, reaching 96.7 ± 0.8% at 8 bar (309 MJ/m3 biogas). The physicochemical properties of granules were not adversely affected by the high pressure, and there was an increase in the production of extracellular polymeric substances (EPS) and carbonic anhydrase gene expression.

Summary: The influence of hydraulic retention time (HRT) on the granulation process, methane-producing capacity, microbial community structure, and pollutant removal efficiency of an up-flow anaerobic sludge blanket (UASB) with simulated municipal wastewater was investigated. The results showed that even at low COD concentrations, the proportion of granular sludge in the UASB was high, and the COD removal efficiency was good. Shortening the HRT resulted in dense granular sludge and reduced the load of subsequent treatment processes.

Summary: In this study, refined sugar wastewater (RSW) was treated using electrodialysis (ED) coupled with an upflow anaerobic sludge blanket (UASB) and membrane bioreactor (MBR). The salt in RSW was first removed by ED, followed by degradation of remaining organic components using the combined UASB-MBR system. The results showed successful removal of salt and organic contaminants, meeting the discharge standard for the sugar industry. This coupled method provides a viable and effective approach for treating RSW and similar high salinity and organic content wastewaters.

Summary: Understanding the impact of phosphorus sources on microalgae growth is crucial for cultivating microalgae. Both inorganic phosphorus and organic phosphorus can be absorbed and utilized by Chlorella pyrenoidosa. The maximum dry cell weight was achieved when the IP/OP ratio was 1:3, which was higher than other combinations. The increase in OP proportion was beneficial for microalgae growth but disadvantageous for lipid accumulation. The use of 31P NMR spectroscopy provided valuable insights into phosphorus metabolism and transformation in microalgae.

Summary: This study developed a recombinant protein expression system specifically for large-scale production in anaerobic hosts, and successfully applied it in Clostridium species. By integrating a codon optimized T7 RNA polymerase, introducing a T7 promoter, and deleting beta-galactosidase genes involved in lactose metabolism, high-level expression of the target gene was achieved. The system was used to express NADP(+)-dependent 3-hydroxybutyryl-CoA dehydrogenase in an anaerobic strain, resulting in a significant increase in recombinant protein yield compared to other expression systems. This optimized system has great potential for large-scale recombinant protein production under strictly anaerobic conditions.

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.
