“…2020), while K. pneumoniae also has demonstrated resistance to third‐generation cephalosporins, including resistance conferred by extended‐spectrum β‐lactamases, and to carbapenems(Herraiz‐Carboné et al . 2021), which may help these two strains to maintain a certain proportion in the early stage. With the continuous process of degradation, the odour produced by Group B was gradually reduced, which is similar to our previous result (Z.H.…”

In our study, we used 16SrRNA and ITS to investigate the microbial community composition and the effect of compound bacterial agent on the microbial community composition in the aerobic composting process of food waste (FW). At the bacterial level, the main phyla of Group A (compost naturally) were Proteobacteria and Firmicutes, and the main species were Pseudomonas_sp._GR7, Bacillus licheniformis and Pediococcus acidilactici. The main phyla of Group B (compost with compound bacterial agent) were Proteobacteria, Firmicutes and Streptophyta, and the main species were Klebsiella pneumoniae, Cronobacter sakazakii, Macrococcus caseolyticus, Enterococcus faecalis, Citrobacter freundii and Bacillus velezensis. It is worth noting that M. caseolyticus may be able to improve the effect of odour which is an important sensory index during aerobic composting. At the fungal level, the main phylum of both Groups A and B was Ascomycota, and the main species of Group A were Paecilomyces variotii, Byssochlamys spectabilis and Aspergillus fumigatus. The main species of Group B were Ogataea polymorpha and Millerozyma farinosa. Finally, the degradation rate of Group B was 81% that was about 15% higher than that of Group A, indicating that the compound bacterial agent could effectively improve the degradation rate and the composting process, while the low abundance of the compound bacterial agent in the composting process might be due to the small initial addition or the inhibition of other bacteria or fungi in the composting process.

The inefficiency of conventional biological processes to remove pharmaceutical compounds (PhCs) in wastewater is leading to their accumulation in aquatic environments. These compounds are characterized by high toxicity, high antibiotic activity and low biodegradability, and their presence is causing serious environmental risks. Because much of the PhCs consumed by humans are excreted in the urine, hospital effluents have been considered one of the main routes of entry of PhCs into the environment. In this work, a critical review of the technologies employed for the removal of PhCs in hospital wastewater was carried out. This review provides an overview of the current state of the developed technologies for decreasing the chemical risks associated with the presence of PhCs in hospital wastewater or urine in the last years, including conventional treatments (filtration, adsorption, or biological processes), advanced oxidation processes (AOPs) and electrochemical advanced oxidation processes (EAOPs).

“…However, the process efficiency is very dependent on the nature of the electrodes, and the concentration and type of supporting electrolyte [4] . Moreover, in presence of chloride ions organochlorinated/toxic byproducts can be formed in electrochemical AOPs [12] , [13] , which restricts the operation conditions for applying such techniques.…”

Highlights Sonodegradation of organic pollutants in ions-rich matrices is critically reviewed. Ultrasound is able to degrade pollutants of diverse nature in ions-rich matrices. Low concentrations of contaminants favor degradation in mineral water and seawater. Efficient pollutants sonodegradation in mineral water or seawater but action in urine is limited. Ecotoxicity and transformations after ultrasound action on matrices must be tested.
