Marine oxygen minimum zones play a crucial role in the global oceanic carbon, nitrogen, and sulfur cycles as they harbor microbial communities that are adapted to water column chemistry redox zonation, turn control greenhouse gas release. These micro-organisms have metabolisms rely on terminal electron acceptors other than O2 often benefit from syntrophic relationships (metabolic coupling). Her...

The effect of chlorine-induced bacterial injury on spectral features using Fourier transform infrared (FT-IR) absorbance spectroscopy was studied using a mixed bacterial culture of (1:1) ca. 500 CFU/mL each Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 15442 in 0.9% saline. Bacterial cells were treated with 0, 0.3, or 1.0 ppm of initial free chlorine (21 degrees C, 1 h of contact ...

background and objectives:infection of pleural fluid is a common disease and because of antibiotic administration, the microbiology of this fluid has changed. the aim of this study was to determine the common bacteria and suitable antibiotics for treatment in pleural effusion (pe). materials and methods: in this cross sectional study, 1210 samples with exudative features were cultured for poss...
