Autolysis of Escherichia coli.
Autolysis of unwashed exponential-phase Escherichia coli cells was efficiently promoted by first submitting them to a quick downshock with distilled water before an upshock with 0.5 M sodium acetate, pH 6.5. The association of these two osmotic shocks had a remarkable synergistic effect and led to significant decreases in turbidity and viability. Different factors influencing the rate of cell l...
متن کاملLight induced expression of β-glucosidase in Escherichia coli with autolysis of cell
BACKGROUND β-Glucosidase has attracted substantial attention in the scientific community because of its pivotal role in cellulose degradation, glycoside transformation and many other industrial processes. However, the tedious and costly expression and purification procedures have severely thwarted the industrial applications of β-glucosidase. Thus development of new strategies to express β-gluc...
متن کاملInvolvement of the relA gene in the autolysis of Escherichia coli induced by inhibitors of peptidoglycan biosynthesis.
It is generally assumed that inhibitors of peptidoglycan biosynthesis do not kill nongrowing bacteria. An exceptional case is reported here. The addition of chloramphenicol to amino acid-deprived cultures of relA+ strains of Escherichia coli which were treated with beta-lactam antibiotics, D-cycloserine, or moenomycin resulted in lysis. This phenomenon is termed chloramphenicol-dependent lysis....
متن کاملProduction of MAG1 Antigen of Toxoplasma gondii in Escherichia coli
Introduction : Toxoplasmosis is a parasitic infection caused by the protozoan Toxoplasma gondii it leads to serious medical problems in congenitally-infected and immunocompromised individuals, while it is quite harmless in immunocompetent individuals. Toxoplasma tissue cyst matrix protein (MAG1) induces early humoral and cell-mediated immune responses. Previous studies suggested recombinant M...
متن کاملCloning of Clostridium perfringens iota toxin gene in Escherichia coli
Iota toxin is produced by Clostridium perfringens type E. This toxin causes antibiotic-associated enterotoxemia in lambs and calves. Iota toxin is a binary toxin that has two components including Ia (the enzyme component) and Ib (the binding component). Ib binds to the surface receptor of target cells and translocate Ia into the cytosol of cells. The aim of this study was to clone toxigenic epi...
