A novel method for promoting conidial production by a nematophagous fungus, Pochonia chlamydosporia AS6.8
A novel method was described for promoting conidial production of nematophagous fungus, Pochonia chlamydosporia AS6.8, by hydrogen peroxide (H2O2) treatment and two-stage cultivation. The fungi were first grown on potato dextrose agar plates to encourage vegetative growth, after briefly treating with 90 mM concentrations of H2O2, and then were transferred to water agar (WA) plates for sporulati...
متن کاملAppendix 1 Methodology for studies on Pochonia chlamydosporia isolates (Rothamsted Research)
Cultures of P. chlamydosporia from infected nematode eggs in soil from different parts of the world have been freeze-dried and retained at Rothamsted Research, prior to use. Eight isolates (five collected from cyst nematode eggs and three from root-knot nematode eggs) were grown on 1.7% corn meal agar (Oxoid, Basingstoke, UK) at 25C prior to use. Chlamydospores used as inoculum were produced in...

متن کاملProduction of hemolysin and other extracellular enzymes by clinical isolates of Pseudomonas pseudomallei.
One hundred clinical isolates of Pseudomonas pseudomallei from humans were tested for their ability to produce extracellular, biologically active substances which are thought to contribute to the virulence of Pseudomonas species. All isolates produced at least on extracellular enzyme; 91 strains were positive for lecithinase, lipase, and protease; but none was positive for elastase. Ninety-thre...
متن کامل[Destruction of Toxocara canis eggs by the nematophagous fungus Pochonia chlamydosporia].
INTRODUCTION Toxocara canis is an ascarid parasite of the small intestine of dogs that causes visceral larva migrans in humans. METHODS With the aim of demonstrating the effectiveness of the fungus Pochonia chlamydosporia on Toxocara canis eggs under laboratory conditions, a trial was set up in Petri dishes with 2% agar-water. RESULTS There was ovicidal activity of 43.8% (p < 0.01) in the t...
