Abstract
Eighty-three bacteria, from a total of 1091, isolated from the rhizoplane of inoculated pasture clovers, inhibited the growth of two Rhizobium trifolii strains. The antagonists belonged to the genera Pseudomonas, Xanthomonas, Achromobacter, Flavobacterium, Alcaligenes, Erwinia, Aerobacter, Bacillus, Streptomyces, Nocardia, Corynebacterium, Arthrobacter, and Brevibacterium. Most, as well as the strongest, antagonists were confined to Pseudomonas. Two distinct groups were recognized within this genus. The A and B groups produced pink water soluble and green fluorescent pigments, respectively.Keywords
