Abstract
The common bacterium Escherichia coli has demonstrated potential in the field of biodegradation. E. coli is naturally capable of biodegradation because it carries a variety of enzymes that are essential for the breakdown of different substances. The degradation process is effectively catalyzed by these enzymes. The collaborative effects of E. coli's aryl sulfotransferase, alkanesulfonate moonoxygenase, and azoreductase enzymes on the breakdown of sulfur dyes from industrial effluents are investigated in this work. ExPASY ProtParam was used to confirm the stability of the enzyme, showing an instability index less than 40. We determined the maximum binding affinities of these enzymes with sulfur dye pollutants - 1-naphthalenesulfonic acid, sulfogene, sulfur green 3, sulfur red 6, sulfur red 1, sulfur yellow 2, thianthrene, thiazone, and thional - using comparative molecular docking. Significantly, the highest binding affinity was shown by monooxygenase (-12.1), whereas aryl sulfotransferase and azoreductase demonstrated significant energies of -11.8 and -11.4, respectively. The interactions between proteins and ligands in the docked complexes were examined. To evaluate their combined effects, co-expression analysis of genes and enzyme bioengineering were carried out. Using aryl sulfotransferase, alkanesulfonate monooxygenase, and azoreductase, this study investigates the enzymatic degradation of sulfur dye pollutants, thereby promoting environmentally friendly and effective sulfur dye pollutant management.

Abstract
A novel series of 1,3,5-triazine-phenylthiazole-pyrazole derivatives were synthesized and subsequently tested for Escherichia coli DNA Gyrase inhibitory activity where they showed excellent inhibitory activity. The top-three ranked DNA gyrase inhibitor (4e, 4g and 4h) were further subjected to antibacterial and anti-biofilm activity against clinical isolates of resistant E. coli strains obtained from Urinary Tract Infection (UTI) patients (CREC81, CREC106, CREC163). Compound 4h was identified as most potent antibacterial agent in the above study. The compound 4h was further evaluated in murine model of E. coli UTI in BALB/c mice infected by transurethral injection of CREC106 strain. Results of the study suggest that compound 4h reduces bacterial load of CREC106 in the treated mice and found approximately equipotent to Novobiocin as standard.

Abstract
MDR UPEC has become a global health challenge. Our study investigates the pairwise interactions among FOS, COL, NIT and TRI against 29 UPEC strains using the checkerboard method. The synergistic combinations are further evaluated for their bactericidal effects against the most resistant strain (MRS) using the time-kill method. The results showed that 100% of these strains were resistant to TRI and NIT, whereas 75·86% of them were susceptible to FOS and COL. Among all tested strains, only seven strains were highly resistant to all used antibiotics. Remarkably, FOS/COL, COL/NIT and COL/TRI combinations represent the most effective synergistic (fractional inhibitory concentration index <1) combinations against the seven strains at MICs lower than the susceptible breakpoint ranges, followed by FOS/NIT and FOS/TRI, which achieved synergistic interactions against 1/7 and 2/7 of these strains. Importantly, the bactericidal effects (reduction ≥3·0 log10 CFU per ml) were only observed with FOS/COL, COL/NIT and COL/TRI combinations against MRS after 24 h of post-treatment. Our data suggested that FOS/COL, COL/NIT and COL/TRI combinations could be a promising option against MDR UPEC infections. Additionally, FOS/NIT and FOS/TRI probably represent a good option for MDR UPEC with lower MICs.

Abstract
The effect of surfactant type and concentration on a bland soap formulation's ability to remove bacteria from hands remains largely unstudied. Several combinations of surfactants and water were combined to test bacterial removal efficacy using a hand-washing device (two pieces of pig skin and a mechanical motor) to simulate a hand wash. A nalidixic acid-resistant, nonpathogenic strain of Escherichia coli (ATCC 11229) was used. Two anionic surfactants, sodium lauryl sulphate and sodium stearoyl lactylate, and two nonionic surfactants, poloxamer 407 and sorbitan monostearate, each in concentrations of 2, 5 and 10% were studied. A slight positive (r2 = 0·17) but significant (P = 0·03) correlation was observed between hydrophile-lipophile balance value and mean log reduction. No correlation was observed between pH of the treatment solution and the mean log reduction (r2 = 0·05, P = 0·25). A 10% sodium lauryl sulphate mixture showed the highest log reduction (x¯ = 1·1 log CFU reduction, SD = 0·54), and was the only treatment significantly different from washing with water (P = 0·0005). There was a correlation between increasing surfactant concentrations above the critical micelle concentration, and mean microbial reduction (r2 = 0·62, P = 0·001). SIGNIFICANCE AND IMPACT OF THE STUDY This study characterizes the role of surfactants in removing microbes during a hand wash. Numerous studies address how surfactants support antimicrobial effect in soap, or cause irritation of skin, but no published studies show which surfactants are best for removing microbes. We used pig skin as a model for human skin and a lathering device to simulate a hand wash. A 10% sodium lauryl sulphate mixture was the only treatment significantly different from a water wash. There was a strong correlation between increasing surfactant concentrations above the critical micelle concentration and mean microbial reduction.

Abstract
Internalization of human pathogens in edible parts of vegetables eaten raw is a major concern, since once internalized they are protected from sanitizing treatments. In this study, we examined the invasion of gfp-labelled Escherichia coli O157:H7 into intact and biotically (infection with Xanthomonas campestris/Pseudomonas syringae) and abiotically (grating with silicon carbide) damaged leaves of wild rocket (Diplotaxis tenuifolia) and Swiss chard (Beta vulgaris subsp. cicla) using laser scanning confocal microscopy. Bacterial cells were found in internal locations of the tissue, irrespective of tissue health status. Contaminated leaf sections of biotically and abiotically damaged wild rocket leaves showed higher susceptibility to microbial invasion, while the pathogen was internalized in greater numbers into intact Swiss chard leaf sections when abiotically, but not biotically, damaged. The greatest differences were observed between the plant species; after surface sanitization, E. coli O157:H7 was still detected in wild rocket leaves, but not in Swiss chard leaves. SIGNIFICANCE AND IMPACT OF THE STUDY Contamination of leafy vegetables with Escherichia coli O157:H7 is a growing problem, as reported outbreaks are increasing. However, establishment of this human pathogen in the phyllosphere is not completely understood. Using laser scanning confocal microscopy, we demonstrated that E. coli O157:H7gfp+ can invade plant tissue of Swiss chard and wild rocket leaves and that the bacterium is more sensitive to surface sanitization of Swiss chard leaves. Damage to leaf tissue promoted leaf invasion, but the nature of the damage (abiotic or biotic) and plant species had an impact.
