a
Sensitivity was determined by plate bioassays in which spores of the indicated Streptomyces species or cells of the other bacterial genera were spread on agar plates and overspotted with supernatant containing inhibitor produced by S. ipomoeae strain 91-03 (see Materials and Methods for details).
b
+, inhibition was observed; −, no inhibition was seen.
