Biofilm is a significant cause for membrane fouling. Antibacterial-coated surfaces can inhibit biofilm formation by killing bacteria. In this study, polyethersulfone (PES) microfiltration membrane was photografted by four antibiotic quaternary ammonium compounds (QACs) separately, which were synthesized from dimethylaminoethyl methacrylate (DMAEMA) by quaternization with butyl bromide (BB), oct...

This investigation introduces the use of an immunoglobulin A mouse myeloma protein for the detection of Salmonella spp. in milk. The immunoglobulin A protein M467 reacts with flagellin from a wide variety of serotypes. Two assays were developed which used an enzyme-linked immunosorbent assay (ELISA) and M467. Alkaline phosphatase was conjugated to M467 (M467-PH), and the presence of Salmonella ...

Type VI secretion systems (T6SS) are macromolecular complexes present in Gram-negative bacteria. T6SS are structurally similar to the bacteriophage cell-puncturing device and have been shown to mediate bacteria-host or bacteria-bacteria interactions. T6SS assemble from 13 to 20 proteins. In enteroaggregative Escherichia coli (EAEC), one of the subassemblies is composed of four proteins that for...

abstract sesbania grandiflora leaves are extensively used locally since ancient time as in traditional systems. base on mainly folkloric use, we investigated to know the potential of sesbania grandiflora leaves extracts through biological works in vivo and in vitro. the ethanolic extract of s. grandiflora leaves was partitioned into ethyl acetate soluble fraction (esf), petroleum ether soluble ...

Active Helicobacter pylori-associated gastritis is characterized by a dense mucosal infiltration with granulocytes. Since H. pylori is noninvasive, secondary signals must induce the accumulation of granulocytes. Interleukin-8 (IL-8) has been shown to play a key role in this event. Using competitive reverse transcriptase-PCR on mRNA from gastric biopsies, we could show a clear correlation betwee...

Pasteurella multocida (P. multocida), A Gram-negative facultative anaerobic bacterium, is a causative animal pathogen in porcine atrophic rhinitis and avian fowl cholera. The outer membrane of Gram-negative bacteria contains of many different protein in very high copy numbers. One of the major outer membrane, the H proteins have functional as high immunogenicity and antigenicity. In this study ...

b-Barrel proteins found in the outer membrane of Gram-negative bacteria serve a variety of cellular functions. Proper folding and assembly of these proteins are essential for the viability of bacteria and can also play an important role in virulence. The b-barrel assembly machinery (BAM) complex, which is responsible for the proper assembly of b-barrels into the outer membrane of Gram-negative ...

The aim of our research was the determination presence and density bacteria musk yeast in fruits vegetables. We also have seen reason to conclude about numerical qualitative reports vegetables which were examinate with heterotrophic bacteria, kaliformet totale yeasts. had curiosity do these data comparison other investigations order give a modest contribution on investigated microflora unit mea...

Peat water treatment still has many obstacles, one of the alternatives that can be used to overcomethis obstacle is membrane technology and UV light variais. This study aims determine effect rayson flux content BOD, TSS, pH, Turbidity, Color E.Coli Bacteria. a combinedmethod, namely ultraviolet (UV) poses using Water Sterilizer, filtration process KUF3 ultrafiltration phytoremediation method wi...
