Inactivation of Staphylococcus aureus in water by pulsed spark discharge

Inactivation of vancomycin-induced unstable L-forms of Staphylococcus aureus by horse serum

Substitution at codon Ser315 of katG gene, a reliable marker for isoniazid (INH) resistance and proliferate in spite of the loss of cell wall is called an L- form. Unstable L- forms  can convert to normal cells but stble L-forms can not.cell wall - deffective state may be induced spontaneously or through the action of an appropriate agent such as antibiotic interfering with the synthesis of cel...

Modulation of Staphylococcus aureus spreading by water.

Staphylococcus aureus is known to spread rapidly and form giant colonies on the surface of soft agar and animal tissues by a process called colony spreading. So far, the mechanisms underlying spreading remain poorly understood. This study investigated the spreading phenomenon by culturing S. aureus and its mutant derivatives on Tryptic Soy Agarose (TSA) medium. We found that S. aureus extracts ...

Removal of Nonylphenol by Pulsed Corona Discharge in Water

Degradation of technical mixture of nonylphenol by the pulsed corona discharge in water has been investigated. It was shown that non-thermal plasma generated by the discharge can effectively remove nonylphenol from water. Degradation of nonylphenol followed first order kinetics. The removal efficiency was dependent on the solution conductivity, while a higher degree of degradation was obtained ...

Aerosol Generation by Spark Discharge*

An aerosol generator producing particles of any desired mobility, equivalent radius, and conducting material has been developed. Particles are formed by electrode atomization in a spark discharge. A high yield of charged particles enables generation of high concentration (> 10’ cmm3) monodisperse aerosols using electrostatic classification. In order to obtain nonagglomerated particles, the aero...
