In order to search for bacteria capable of reducing the aflatoxin contamination of cottonseed, 892 indigenous bacterial isolates, including 11 that were endophytic to cotton, were screened for their ability to inhibit the growth of Aspergillus flavus on cottonseed in an in vitro bioassay. Only six isolates partially or totally inhibited fungal growth. All antagonistic isolates were recovered from boll, lint or seed surface or from the lint of mature bolls. One was retrieved from mature seeds. None of the endophytic isolates showed activity. In four field trials, the incidence of A. flavus -induced damage to locules inoculated simulteously with A. flavus plus the most A. flavus plus the most effective antagonistic isolate (D1) was reduced by 41-100% relative to locules inoculated with A. flavus alone. The severity of damage to locules inoculated simultaneously with A. flavus and with D1 was reduced by 60-l00% relative to locules inoculated with A. flavus alone. Isolate D1, identified as Pseudomonas cepacia, completely inhibited the growth of A. flavus on synthetic media. |
