corn steep water as effluent which arrives in environment from starch processing industry has adverse effects on the environment and also large volume of fresh water is wasted. corn step water is composed of high concentration of proteins, sugar, starch, vitamin and minerals, so it can be used as substrate for production of biological products. hence, corn steep water concentration is important...
Outer membrane vesicles (OMVs) are secreted by Gram-negative bacteria via outward budding of the outer membrane. It plays an important role in bacterial-host communication and can modulate host immune response. There limited approaches for fast precise evaluation OMVs secretion. In article e312, Chen, Zhao, coworkers reported a light-up fluorescent AIE probe efficient detection high-throughput ...
introduction: legionnair's disease bacterium is a gram negative, facultative intracellular bacilli which parasitize human alveolar macropages as well as some species of free living amobae. this study was achieved in order to compare the cell wall composition in intracellular bacteria. whole cell and outer membrane proteins and the bacterial lipopolysacharide (lps) were analyzec on sds page syst...
methods mycobacterium tuberculosis standard strain crbip7.11 was cultured at 37°c in loewenstein johnson (lj) media for 3-4 weeks. to confirm the species, standard microbiological and biochemical tests were performed. after preparation of membrane vesicles, the amount of protein in membrane vesicles was measured by sds-page and nanodrop. to analyze the integrity and morphology of extracellular ...
This review presents a brief outline of our current knowledge of the structure and chemical composition of the outer membrane vesicles (OMVs), originating from the surface of Gram negative bacteria including their outer membrane proteins and lipopolysaccharides. Moreover, the functional roles and applications of OMVs in medical research such as OMV-based vaccines, OMV adjuvants properties, OMV ...
The photodynamic inactivation of the membrane functions of bacteria was analyzed in situ, using K(+) and tetraphenylphosphonium (TPP(+)) electrodes, as well as an oxygen electrode. Tetrakis(4-N-trimethylaminophenyl)porphine (TTMAPP) and rose bengal were used, since both dyes act strongly on bacteria, such as Staphylococcus aureus. After a short time lag, they inhibited the respiration of bacter...
