Autolysis and secondary growth of Mycobacterium tuberculosis in submerged culture.
Mycobacterium tuberculosis has been found to exhibit autolysis and spontaneous secondary growth in modified Sauton medium. The phenomenon is a function of high glycerol concentration of the medium and limitation of air in test tubes. It is not a function of depletion of nutrients and is probably not a manifestation of lysogeny or spheroplast formation. The cycle of growth, autolysis, and second...
متن کاملInhibition of pneumococcal autolysis in lysis-centrifugation blood culture.
The recovery of Streptococcus pneumoniae from the Isolator lysis-centrifugation blood culture has been low in many studies. The poor survival of pneumococci was not due to toxicity of the Isolator medium but to autolysis before plating. This autolysis was completely inhibited by adding 10 mM phosphorylcholine to the Isolator medium.
متن کاملPure Culture of Pseudomonas cepacia
A pure culture of Pseudomonas cepacia, designated AC1100, that can utilize 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) as its sole source of carbon and energy was isolated. An actively growing culture of AC1100 was able to degrade more than 97% of 2,4,5-T, present at 1 mg/ml, within 6 days as determined by chloride release, gas chromatographic, and spectrophotometric analyses. The ability of AC...
متن کاملBringing Planctomycetes into pure culture
Planctomycetes have been known since the description of Planctomyces bekefii by Gimesi at the beginning of the twentieth century (1924), although the first axenic cultures were only obtained in the 1970s. Since then, 11 genera with 14 species have been validly named and five candidatus genera belonging to the anaerobic ammonium oxidation, anammox bacteria have also been discovered. However, Pla...
متن کاملIsolation of Nitrosomonas in pure culture.
Although it has been 68 years since Winogradsky (1890) accomplished the first isolation of nitrifying bacteria, the methods employed have not been improved significantly, and pure cultures remain incredibly difficult to obtain. The literature records numerous attempts to secure Nitrosomonas in pure culture. Nevertheless, the organism has seldom been isolated by dilution techniques. In the relat...
