A set of 12 out of 38 Bacillus strains isolated from peanut geocarposphere soil were screened as potential biological control agent anti-Aspergillus parasiticus
These 12 Bacillus strains were selected of promoting peanuts germination rate.Pot experiment in greenhouse was carried out by using these strains which can promote peanuts germination
These Bacillus strains isolated from peanut geocarposphere soil not only had high ability anti-Aspergillus
parasiticus, but also promoted peanut growth.
Phytohormones in
the fermentation broth were also detected as another important reference factor to select the isolates as biological control agent
with PGPR features
An important factor to consider when selecting bacteria
is their activities in the range of environments in
which they would be expected to be used (Mickler et al.
1995). Taking this into account, the Bacillus strains with
bacterial antagonists of A. parasiticus activity which are
isolated from region of peanut geocarposphere soil, were
selected for this study.
