Effect of high pressure and sub-zero temperature on some gram-negative bacteria.
PublicationCelem pracy było określenie przeżywalności wybranych gramujemnych bakterii na działanie wysokiego ciśnienia i ujemnej temperatury. Traktowanie komórek bakterii ciśnieniem 193 MPa w temperaturze -20C przez 24 godziny, powodowało całkowitą inaktywację bakterii E. coli, P. fluorescens i T. thermophilus. Po działaniu ciśnienia przez krótszy czas występowały różnice we wrażliwości między badanymi szczepami. Najmniej odporny na działanie...

A Novel Cryptic Clostridial Peptide That Kills Bacteria by a Cell Membrane Permeabilization Mechanism
PublicationThis work reports detailed characteristics of the antimicrobial peptide Intestinalin (P30), which is derived from the LysC enzyme of Clostridium intestinale strain URNW. The peptide shows a broader antibacterial spectrum than the parental enzyme, showing potent antimicrobial activity against clinical strains of Gram-positive staphylococci and Gram-negative pathogens and causing between 3.04 ± 0.12 log kill for Pseudomonas aeruginosa...

Whole-genome sequencing and antimicrobial potential of bacteria isolated from Polish honey
PublicationThe aim of this study was the whole-genome analysis and assessment of the antimicrobial potential of bacterial isolates from honey harvested in one geographical location—the north of Poland. In total, 132 strains were derived from three honey samples, and the antimicrobial activity of CFAM (cell-free after-culture medium) was used as a criterion for strain selection and detailed genomic investigation. Two of the tested isolates...

Characterization of single-stranded DNA-binding proteins from the psychrophilic bacteria Desulfotalea psychrophila, Flavobacterium psychrophilum, Psychrobacter arcticus, Psychrobacter cryohalolentis, Psychromonas ingrahamii, Psychroflexus torquis, and Photobacterium profundum
PublicationBackground: Single-stranded DNA-binding proteins (SSBs) play essential roles in DNA replication, recombination and repair in Bacteria, Archaea and Eukarya. In recent years, there has been an increasing interest in SSBs, since they find numerous applications in diverse molecular biology and analytical methods. Results: We report the characterization of single-stranded DNA-binding proteins from the psychrophilic bacteria Desulfotalea...

Effect of lysozyme or nisin on survival of some bacteria treated with high pressure at subzero temperature
PublicationCelem pracy było określenie wrażliwości gramujemnych i gramdodatnich bakterii na działanie ciśnienia 193MPa w temp. -20°C w obecności lizozymu lub nizyny. Stwierdzono, że połączone działanie ciśnienia i badanych substancji przeciwdrobnoustrojowych na zawiesiny bakterii Escherichia coli i Staphylococcus aureus powodowało większy stopień inaktywacji komórek niż suma efektów wywieranych przez pojedyncze czynniki.

A New Double Digestion Ligation Mediated Suppression PCR Method for Simultaneous Bacteria DNA-Typing and Confirmation of Species: An Acinetobacter sp. Model
PublicationWe have designed a new ddLMS PCR (double digestion Ligation Mediated Suppression PCR) method based on restriction site polymorphism upstream from the specific target sequence for the simultaneous identification and differentiation of bacterial strains. The ddLMS PCR combines a simple PCR used for species or genus identification and the LM PCR strategy for strain differentiation. The bacterial identification is confirmed in the...

Enhancement of photocatalytic-based processes by mono- and bimetallic (CuPd) rutile loaded nanoparticles for antibiotic resistance genes and facultative pathogenic bacteria removal
PublicationThe aim of the study was the strong reduction of facultative pathogenic bacteria (FPB), and clinically relevant antibiotic resistance genes (ARGs) from secondary effluent. To evaluate the ARGs removal efficiency comparative study of individual unit processes and combined AOPs has been performed. The present work investigated: i) removal of selected ARGs, namely blaTEM, ermB, qnrS, tetM, five FPB as well as 16S rDNA and the integrase...
