culture filtrates (cf) of two species of the nematophagous fungi, arthrobotrys oligospora and arthrobotrys conoidesat three concentrations (25%, 50% and 100%) of stock, were tested on the mortality of second stage juveniles (j2) and egg hatching rate of meloidogyne incognita and meloidogyne javanica. results showed that the percent juvenile mortality was directly proportional to concentration o...

We tested a formulation composed of a mixture of Bidens pilosa var. radiata extract (BPE) and nematode-trapping fungi for its effects on Meloidogyne incognita. In earlier evaluations of the effects of plant extracts on the hyphal growth of 5 species of nematode-trapping fungi with different capture organs (traps), the growth of all species was slightly inhibited. However, an investigation on th...

Eleven fungal isolates were tested in agar dishes for pathogenicity to Pratylenchus penetrans. Of the fungi that produce adhesive conidia, Hirsutella rhossiliensis was a virulent pathogen; Verticillium balanoides, Drechmeria coniospora, and Nematoctonus sp. were weak or nonpathogens. The trapping fungi, Arthrobotrys dactyloides, A. oligospora, Monacrosporium dlipsosporum, and M. cionopagum, kil...

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...

Abstract Improved understanding of cellulose swelling mechanism is beneficial for increasing the hydrolysis efficiency cellulosic substrates. Here, we report a family 5 glycoside hydrolase ArCel5 isolated from cellulose-gelatinizing fungus Arthrobotrys sp. CX1. exhibited low specific activity and high capability, which suggested that this protein might function as an accessory protein. Homology...
