Summary: This study investigated the effect of increasing the organic loading rate (OLR) on the co-fermentation of glycerol and sugarcane vinasse in a thermophilic anaerobic fluidized bed reactor. The highest hydrogen production rate and yield were observed at an OLR of 120 kg COD m-3 d-1, with butanoate as the major liquid metabolite. The synthesis of butanoate was attributed to the reverse b-oxidation of lactate and the synergistic interaction between Clostridium and Lacti-caseibacillus in the reactor.

Summary: Microbial electrodes were used to enhance electron transfer in lactic acid anaerobic digestion system, reducing the inhibition effect of propionic acid on methane production. Excitation-emission matrix fluorescence spectroscopy analysis showed that electrochemical treatment changed the intercellular electron transfer pathway and reduced the content of humic acids. The abundance of electron-producing bacteria Firmicutes and hydrogenotrophic methanogens Methanoculleus increased, leading to more electron generation and methane production.

Summary: The study found that aerobic Gammaproteobacterial methanotrophs dominate in assimilating CH4 under anoxic conditions in Arctic lakes, and these methanotrophs have the capacity to generate intermediates such as methanol, formaldehyde, and formate from CH4 oxidation. This expands the knowledge of aerobic methanotroph metabolic processes and suggests potential coupling of CH4 oxidation to iron reduction in the Arctic lakes.

Summary: This study proposes a laboratory-scale biorefinery strategy for orange peel waste (OPW), which includes ensiling, adding biological and chemical supplements, and anaerobic digestion (AD). The strategy successfully preserves the methane potential and stimulates the production of value-added compounds. The solid fraction of OPW, separated after long-term ensiling, retains about 50% of the methane potential of fresh OPW. Semi-continuous AD results in stable methane production even though nutrient supplementation is needed.

Summary: This study investigated the treatment of dairy processing wastewater (DPW) using high-solid anaerobic membrane bioreactor (AnMBR). The results showed that a high microbial concentration achieved efficient methane production, while lactic acid bacteria (LAB) were gradually eliminated under high organic loading rates (OLRs). The study also found that increasing the solid concentration limited membrane flux and led to membrane fouling. Organic foulants dominated membrane resistance and resulted from the high rejection efficiency of organic matter. This study provides a novel and effective approach for high-rate DPW treatment and offers significant guidance for the dairy industry in wastewater treatment development.

Summary: Anaerobic technologies play a crucial role in sewage treatment and recovering marketable products from waste, but they often lead to methane oversaturation and lack of nitrogen removal. However, combining methane oxidation with denitrification processes can address both issues simultaneously.

Summary: Tidal-induced shifts of n-DAMO activity and associated contribution to mitigating CH4 in intertidal wetlands were studied. The study found that the wetting-drying events caused by tidal cycling had significant effects on the abundance and activity of n-DAMO microbial communities. The presence of n-DAMO bacteria and archaea and their higher biodiversity under reflooded conditions were also observed. Structural equation modeling and correlation analysis indicated that n-DAMO activity was influenced by microbial abundance, substrate availability, and salt accumulation in sediment. This study provides valuable insights into accurately estimating CH4 emissions from intertidal wetlands under different tidal scenarios.

Summary: This study conducted a systematic review and meta-analysis to assess the impact of hydrofiber dressings on reducing complications in total joint arthroplasty surgeries. The results showed that hydrofiber dressings had no observable effect on prosthetic joint infection and wound irritation, but they did reduce the rate of blisters and the number of dressing changes. However, the evidence for the reduction in blisters and dressing changes is limited due to biased trial methodologies and wide confidence intervals.

Summary: Understanding the causes and circumstances of death in extremely preterm infants is crucial for healthcare practitioners. This study retrospectively examined a cohort of infants born between 24 and 27 weeks of gestation to determine the risk factors, causes, timing, and circumstances of death. The study found that respiratory distress or failure, pulmonary hemorrhage, necrotizing enterocolitis, catastrophic intracranial hemorrhage, sepsis, and sudden unexplained death were the primary causes of death. The risk of death decreased over time, and preterm labor was associated with a decreased hazard of death. Clinical factors such as low birth weight, low Apgar score, sick appearance at birth, necrotizing enterocolitis, pulmonary hemorrhage, severe intracranial hemorrhage, and severe sepsis were also associated with death.

Summary: This study investigates the impact of variables such as climate, landscape composition, management practices, and wild bee pollination on commercial apple production. The results show that apple yields are mainly influenced by management practices, not the contribution of managed honey bees. Wild bee diversity is negatively correlated with honey bee dominance but promotes apple quality. Thus, harnessing wild bee diversity can be a nature-based solution and a substitute for an exclusive reliance on honey bees in apple production.

Summary: Establishing a higher classification of bees based on morphology alone can fail to capture evolutionary relationships. In the subfamily Panurginae, two Old World species previously placed in separate genera were found to be most closely related to each other. To address this, a new genus was established and the classification of the tribe was reassessed. The study highlights the challenges of establishing a phylogenetically sound classification and the existence of unrecognized genera, even in well-studied regions.
