“…More and more evidences about the toxic effects of 4,4'-Isopropylidenediphenol (BPA) were reported (Bernardo et al 2021, Tišler et al 2016. In order to meet the restrictions and regulations, manufacturers are gradually using 4,4'-sulfonyl-diphenol (BPS) instead of BPA as a substitute for industrial applications (Cai &Zhang 2022).…”

BPS, as a widespread environmental hormone-like micro-pollutants, is di cult to be degraded in the environment. In this study, the removal of BPS with multi-enzymes extracted from waste sludge and reed sediment were studied at 25℃, 37℃ and 55℃. Results show that BPS could be removed e ciently, which could involve enzymolysis and bio-occulation. The mechanism and pathways of the enzymolysis were identi ed with LC-MS/MS. Polymerization of BPS with enzymolysis further improved the removal by bio-occulation due to the production of BPS oligomers. Furthermore, the interaction mechanism between BPS and multi-enzymes was explored through a series of spectroscopic experiments. Results show that more loose skeletal structure of the multi-enzymes and more hydrophobic microenvironment of the amino acid residues are responsible for the removal of BPS. This research not only provided a method for refractory micropollutants removal but also a way for the utilization of waste sludge and reed sediment.

“…18 The solvent is used for solid/liquid extraction, and the desolvation occurs without any sheath gas. 19 Given its simplicity, PS-MS has been extensively used for the detection of fentanyl and pharmaceuticals, ranging from powdered drug samples, 20 bisphenol S in thermal paper samples, 21 and antibiotic sulfamethazine in pig body fluids. 22 Additionally, as reported in the literature, PS-MS has been applied for the diagnostics of prostate cancer in urine 23 and analyses of creatinine concentration in whole blood, 24 exemplifying the versatility of the technique.…”

Paper spray mass spectrometry (PS-MS) is an ambient ionization technique that allows for rapid and direct mass spectrometry analysis for a wide range of chemical compounds due to its portability, little to no sample preparation, and cost-effective materials. As applications with this technique continue to expand, the identification and discrimination of bacteria at the strain level remain a promising avenue for researchers. Although studies in the past demonstrated the applicability of PS-MS to discriminate bacteria at the strain level, no one has reported the strain-level differentiation of actinobacteria without using solvent for PS-MS. Hence, this study demonstrates that optimization of PS-MS permits the investigation and differentiation of the metabolic profiles of actinobacteria without the need for solvents, diminishing the potential for sample contamination and consequently increasing the versatility of this technique. In doing so, strains of actinobacteria (CAAT P5-21, CAAT P5-16, CAAT 8-25, CAAT P8-92, and CAAT P11-13) were grown and transferred to produce a crude growth medium. The supernatant was used for the PS-MS analyses using a Thermo Scientific LTQ mass spectrometer. Multivariate statistical analysis, including principal component analysis (PCA) and hierarchal cluster analysis (HCA), was employed to chemically distinguish the strains of bacteria. As a result, each strain of actinobacteria could be visually differentiated based on their metabolic profile.These findings demonstrate the practicability of using a liquid medium as an alternative to many other organic solvents when analyzing bacteria, making PS-MS a crucial addition to a microbiologist's research toolkit.
