A beige-pigmented, oxidase-positive bacterial isolate, Wesi-4, isolated from charcoal in 2012, was examined in detail by applying a polyphasic taxonomic approach. Cells of the isolates were rod shaped and Gram-stain negative. Examination of the 16S rRNA gene sequence of the isolate revealed highest sequence similarities to the type strains of and (both 97.3 %). Phylogenetic analyses on the basis of the 16S rRNA gene sequences indicated a separate position of Wesi-4, which was confirmed by multilocus sequence analyses (MLSA) based on the three loci , and and a core genome-based phylogenetic tree. Genome sequence based comparison of Wesi-4 and the type strains of and yielded average nucleotide identity values <95 % and DNA-DNA hybridization values <70 %, respectively. The polyamine pattern contains the major amines putrescine, cadaverine and spermidine. The quinone system contains predominantly ubiquinone Q-9 and in the polar lipid profile diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine are the major lipids. The fatty acid contains predominantly C, summed feature 3 (Cω7 and/or Cω6) and summed feature 8 (Cω7 and/or C ω6). In addition, physiological and biochemical tests revealed a clear phenotypic difference from . These cumulative data indicate that the isolate represents a novel species of the genus for which the name sp. nov. is proposed with Wesi-4 (=DSM 110367=CIP 111764=CCM 9017) as the type strain.

The most important aspect of sorbent-based approaches is the use of a sustainable, readily available, and cost-effective sorbent material for sample analysis. Biochar is an emerging and prominent sorbent material for various applications in sorbent-based techniques due to its availability, affordability, eco-friendly nature, porosity, pore structure, abundance of aliphatic and aromatic carbon structures, and abundant oxygen-containing functional groups. On the basis of the numerous benefits of biochar, this review discusses why biochar is the preferred sorbent in sorptive-based techniques.

Antimicrobial resistance (AMR) is a major cause of death worldwide, with 1.27 M direct deaths from bacterial drug-resistant infections as of 2019. Dissemination of multidrug-resistant (MDR) bacteria in the environment, in conjunction with pharmapollution by active pharmaceutical ingredients (APIs), create and foster an environmental reservoir of AMR.

The widespread use of antibiotics such as fluoroquinolones (FQs) has raised environmental and health concerns. This study is innovative as we investigate the removal of ciprofloxacin (CIP) and norfloxacin (NOR) from water using activated carbon derived from cupuaçu bark (CAC). This previously discarded biomass is now a low-cost raw material for the production of activated carbon, boosting the local economy.
