Oral antibiotic prophylaxis induces changes in the microbiology of surgical site infection after colorectal surgery. A matched comparative study.
Colorectal Dis
February 2025
Department of Infectious Diseases, Hospital Universitari Parc Taulí, Sabadell, Spain.
Aim: Oral antibiotic prophylaxis (OAP) lowers rates of surgical site infection (SSI) and may aid anastomotic healing in colorectal surgery. The aim of this study was to analyse the understudied impact of OAP on SSI microbiology after colorectal surgery.
Method: A post hoc analysis was performed on a previous prospective, multicentre study of elective colorectal surgery.
Biological VFAs production from proteinaceous wastewater varied with protein type: The role of protein exposed enzyme cleavage sites and hydrolysates biotransformation capacity.

State Key Laboratory of Pollution Control and Resources Reuse, School of Environmental Science and Engineering, Tongji University, 1239 Siping Road, Shanghai 200092, PR China. Electronic address:
Proteinaceous wastewater contains various proteins, which can be valorized to biobased volatile fatty acids (VFAs), important substrates for the synthesis of biodegradable plastics, biodiesel, bioelectricity, etc., but the influence of protein type on VFAs has never been documented. It was found that among the five proteinaceous wastewater proteins investigated, ovalbumin and casein produced the most and the least VFAs, respectively.

Granular activated carbon (GAC) and GAC modified with anthraquinone-2-sulfonate (AQS) were used as conductive materials during the anaerobic digestion of swine wastewater (SW). The electron transfer capacity (ETC) in the GAC-AQS was 2.1-fold higher than the unmodified GAC.

College of Resource and Environmental Science, Hubei University, Wuhan, China.
Bioremediation of trichloroethene (TCE)-contaminated sites often leads to groundwater acidification, while nitrate-polluted sites tend to generate alkalization. TCE and nitrate often coexist at contaminated sites; however, the pH variation caused by nitrate self-alkalization and TCE self-acidification and how these processes affect nitrate reduction and reductive dichlorination, have not been studied. This study investigated the interaction between nitrate and TCE, two common groundwater co-contaminants, during bioreduction in serum bottles containing synthetic mineral salt media and microbial consortia.

Institute of Environmental Processes and Pollution Control, and School of Environment and Ecology, Jiangnan University, Wuxi 214122, China.
The interplay between root exudates and rhizobacteria is essential for enhancing agricultural productivity. Herein, the impacts of cerium dioxide nanomaterials (CeO NMs) on these interactions in soybean plants were investigated. Following 3-5 weeks of exposure to 5 mg·kg CeO NMs, the composition of root exudates changed over time, with isoflavone levels increasing by 6.
