Summary: This study found that micro-aerobic conditions during composting can improve the quality of compost products. Compared to static composting, micro-aerobic composting degrades lignocellulose at a slower rate but increases the content of dissolved organic carbon. It also affects the degradation of carboxyl carbon and alcohol/ether, and promotes the emissions of carbon dioxide and methane. Additionally, micro-aerobic composting reduces the relative abundances of pathogenic and dung saprotrophic fungi while increasing the relative abundance of soil saprotrophs.

Summary: Effluent is often treated with ozone before being discharged into natural water environments, impacting the complexation between dissolved organic matter and pollutants. Ozone treatment decreases the molecular weight and aromaticity of organic matter, while enhancing the complexation of humic and fulvic acids with sulfadimidine. Additionally, dissolved organic matter weakens sulfadimidine's inhibition of microbial growth in the water, especially for specific species like Aeromonas and Acinetobacter.

Summary: The effects of polyethylene (PE) and biodegradable polylactic acid (PLA) microplastics on soil organic matter (SOM) stability and bacterial community were examined in two contrasting soils under varying temperature conditions. Results showed that microplastics addition significantly increased CO2 emissions and dissolved organic carbon (DOC) contents, with PLA being more susceptible to elevated temperature compared to PE. The presence of microplastics also altered the spectral characteristics of DOC and affected the soil bacterial community. The findings suggest the non-ignorable effect of microplastics on soil organic matter stability and the need to consider the interaction between microplastics and soil environment.

Summary: This study investigated the various advanced treatment processes for the secondary effluent of municipal wastewater treatment plants and their impact on dissolved organic matter (DOM) and disinfection byproduct (DBP) generation. The results showed that the biological aerated filter (BAF) and ozonation processes significantly affected DOM characteristics and subsequent DBP generation. Low molecular weight hydrophobic DOM removal resulted in a reduction in DBP production, while ozonation led to an increase in halogenated aldehydes (HALs) and halogenated ketones (HKs). Humic acid (HA) was identified as the main organic type in DOM and an important precursor for DBPs. The specific ultraviolet absorbance at 254 nm (SUVA) was found to be a critical factor for trichloromethane (TCM) generation. Large molecule hydrophobic DOM contributed the most to the formation of carbonaceous disinfection by-products, and NH4+-N content affected the generation of nitrogenous disinfection by-products.

Summary: One of the largest uncertainties of global warming is the effect of microbial decomposers on soil C-climate feedback. Despite decades of research, the strength of this feedback remains unknown. This study found that microbial temperature traits vary systematically with climate and can affect the feedback between the soil C cycle and climate warming. The adaptation of microbial temperature trait distributions to a warming climate emphasizes the need to accurately represent this feedback in Earth system models.

Summary: Climate change is expected to affect soil drying-rewetting (D/RW) and freezing-thawing (F/TW) events, with consequences for microbial activities. Previous research has shown that microbial responses to D/RW can either be resilient or sensitive, but it remains unknown if these responses also occur after F/TW. This study compared microbial responses to D/RW and F/TW and found that both events can induce distinct microbial perturbation responses, with F/TW imposing a similar but less severe stress on soil microorganisms compared to D/RW. However, microbial carbon-use efficiency (CUE) remains stable in response to both types of perturbation.

Summary: Soil microbial growth and activity showed delayed recovery after the dissipation of four readily degradable isothiazolinone biocides. Bacterial growth and fungal growth were the most sensitive endpoints during the initial stages. Despite the dissipation of biocides, all isothiazolinones inhibited bacterial growth for more than 7 days and fungal growth and substrate-induced respiration for up to 40 days. The study highlights the delayed recovery of soil microbial functions and suggests that the delayed recovery of fungal growth compared to bacterial growth may be a common phenomenon during the dissipation of toxicants in contaminated soils.

Summary: Antibiotics pollution is a growing concern in the environment, with high levels of these compounds being found in soil, water, and sediments. This study investigates the adsorption/desorption processes of the macrolide antibiotic clarithromycin (CLA) in different agricultural soils, highlighting the influence of various soil characteristics. The results show varying levels of CLA adsorption, with the silt fraction content and exchangeable Ca content having the strongest influence. Desorption was found to be lower than adsorption, with factors such as total nitrogen, organic carbon, and exchangeable Ca and Mg contents influencing the process. pH values did not significantly impact the adsorption/desorption process. These findings can be used to develop effective strategies to mitigate the presence of antibiotics in the environment.

Summary: The microbial use of resources such as carbon, nitrogen, and phosphorus plays a crucial role in decomposition and nutrient provisioning to plants. This study investigates the limiting factors for soil microorganisms in a subarctic tundra heath and examines the impact of climate change on resource availability. The results show that carbon and phosphorus are the primary limiting factors for microbial growth, with nitrogen also playing a secondary role. The availability of carbon is alleviated by litter treatment but intensified by nitrogen fertilization. Bacteria are found to be closer to phosphorus limitation compared to fungi. The findings suggest that climate change-induced changes in resource availability will affect microbial resource limitation, potentially leading to competition between plants and microorganisms and altering ecosystem productivity.
