Summary: Production of medium chain fatty acids (MCFAs) from excess sludge has gained research interest due to its higher energy densities, easy-separation capability, and economic benefits. In this study, the addition of chain elongation (CE) enrichments with ethanol as electron donor enhanced caproate production from one-stage sludge fermentation. By supplementing CE enrichments with a ratio of ethanol/acetate of 3:1, caproate production reached 9.00 g/L after 7 days of acidification of organic matter in pretreated sludge fermentation. The enrichment of Clostridium_sensu_stricto_12, referring to CE, in the sludge microbial consortium played a crucial role in achieving stable and efficient caproate production.

Summary: It is observed that the ratio of nitrite consumption to ammonia consumption in Anammox systems is lower than its stoichiometry, but the reason remains unknown. This study found that the addition of Fe(OH)3 significantly decreased the ratio of nitrite to ammonia consumption in an Anammox system. The reduction of Fe(OH)3 likely served as an extracellular electron acceptor, facilitating NH4+ oxidation via Feammox pathway.

Summary: This study investigated the effect of bioaugmentation on the hydrolysis and acidogenesis efficiency of bedding straw mixed with maize silage. The results showed that bioaugmentation increased the hydrolysis rate and acid production, but had no significant effect on mixtures with a high straw content. Bioaugmentation also had a positive impact on the physiological state of the cultures and this effect was maintained for a certain period of time during continuous fermentation. These findings provide a basis for optimizing the use of bioaugmented microorganisms and the hydrolysis of biogenic material in terms of sustainable process performance and costs.

Summary: Sulfonated amorphous carbon catalyst (AC-SO3H) was synthesized through the partial carbonization and sulfonation of rice husk, and it exhibited exceptional catalytic activity in organic synthesis. The catalytic activity of AC-SO3H in the synthesis of 3-cyanoacetamide pyrrole was investigated, and the influence of amine derivatives on the reaction outcome and by-product formation was studied. The main product was obtained in yields up to 67%. The catalyst showed negligible reduction in activity after leaching and could be easily recovered and reused.

Summary: Thermal hydrolysis (TH) pretreatment, used in anaerobic digestion (AD), has been proven effective in the laboratory and utilized in engineering. However, the properties of AD liquid (ADL), such as high organic matter and ammonia nitrogen concentration, present challenges in subsequent treatment. To overcome this, the autotrophic nitrogen removal (ANR) process is developed. This paper reviews the TH-ADP and ANR mechanisms, addresses difficulties in treating TH-ADL, evaluates current research status, and proposes potential solutions.

Summary: Racemic 3-substituted oxindoles can be converted into enantiomerically pure or enriched material through photochemical deracemization process. Light energy compensates for the loss of entropy and enables predictable editing of the stereogenic center. The obtained oxindoles are valuable intermediates for further transformations with complete retention at the stereogenic center.

Summary: The first asymmetric (3+3)-cycloaddition of ortho-substituted phenyl nitrones with aryl cyclopropane carbaldehydes has been achieved using secondary amine catalysts. While other ortho-substituents gave 1,2-oxazinanes, ortho-hydroxy compounds provided a novel class of tetrahydrochromeno-1,2-oxazine cores through rare 1,3-aryl migration followed by cyclization. An unusual type of asymmetric approach was also discovered.

Summary: Electrocatalytic biomass valorization has gained increasing interest, but reports on pyridine-containing chemicals from biomass upgrading are rare. In this study, we describe an electrochemical synthesis of 3-pyridinol from biomass-derived furfurylamine, achieving a 97% yield. The use of a Br-/Br+ redox cycle and strong acidic conditions was crucial for driving the final dehydration step. Control experiments and computational investigations were conducted to elucidate the key mechanistic steps of the one-pot conversion of furfurylamine to 3-pyridinol.

Summary: A cellulose-degrading anaerobic bacterium Paracoccus sp. Strain LZ-G1 was isolated from cow dung, capable of degrading cellulose and adsorbing Cd2+. Bioaugmentation with this strain in an AD system significantly increased biogas and methane production from HM-containing plant residues and cow manure. Restoration of the microbial community by LZ-G1 bioaugmentation improved biogas yield and methane production rate during the AD process.

Summary: Anaerobic fungi have great potential in the biofuel and biogas industries for their ability to degrade lignocellulose. However, the engineering tools for anaerobic fungi have not been established yet. Pre-treatment of lignocellulose by anaerobic fungi can prevent carbohydrate loss and increase biogas production. Bioaugmentation with anaerobic fungi can significantly enhance methane biosynthesis. Nonetheless, novel genetic engineering techniques and tools are needed for the commercial anaerobic digestion process.

Summary: The coal chemical energy industry has rapidly developed in China due to the primary position of coal in energy reserves, but it also faces issues of high water consumption and wastewater pollution. Current wastewater treatment technologies mainly involve gas stripping and extraction methods, while negative pressure extraction measures are needed in microbiological treatment systems. Further research is required for effective treatment methods for concentrated brine and crystal salt.

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.
