The yeast Williopsis mrakii produces a mycocin or yeast killer toxin designated HMK; this toxin exhibits high thermal stability, high pH stability, and a broad spectrum of activity against other yeasts. We describe construction of a synthetic gene for mycocin HMK and heterologous expression of this toxin in Aspergillus niger. Mycocin HMK was fused to a glucoamylase protein carrier, which result...
Trophic interactions of introduced biocontrol fungi with soil animals can bea key determinant in the fungal proliferation and activity.This study investigated trophic interaction of an introduced biocontrol fungus with soil nematodes. The biocontrol fungusTrichoderma harzianum ThzID1-M3 and the fungivorous nematode Aphelenchoides sp. (10 per gram of soil) were added to nonsterile soil, and micr...

—I hypothesized that the naturally elevated Ni concentration of Melanotrichus boydi (718–789 mg g21) might protect this insect species against pathogen attack. I contrasted survival of M. boydi against survival of the low-Ni mirid Lygus hesperus when treated with three entomopathogenic biocontrol agents. Biocontrol agents used were the fungus, Beauveria bassiana, and infective juveniles of two ...
Fire products (smoke, ash and heat) have widely been recognized as a germination cue for some species from both fire prone and fire-free ecosystems. It is an important factor for the understanding of vegetation dynamics and could have potential use for ecological management and rehabilitation of disturbed area. This study attempts to understand the effect of the main fire products (smoke, ash a...
abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...
in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized complete block by five treatments and four replication, including, indoxacarb (avant)®, trichogrammawasps, bacillus thuringiensis var: kurstaki, integration of trichogramma sp. and bt., and control as treatments number 1 to 5. in treatments with parasitoid re...

debaryomyces hansenizopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by ulocladium. chartarum(pr.) simm. the ability of d. hansenii to prevent infection of u. chartarum was lost when the antagonist cells were killed by autoclaving. cell free culture filtrates of antagonist were unable to prevent disease incidence. efficacy ...
