Abstract

In order to select microorganisms able to produce plant growth promoters, previously isolated rhizobacteria were grown in a liquid medium. After cell removal by centrifugation, the liquid phases were freeze-dried and extracted with ethyl acetate. Once concentrated under vacuum, the extracts were dissolved in 6 mL of a sucrose solution and submitted to an assay with wheat (Triticum aestivum L.) coleoptiles. Among the rhizobacteria used in this work, one strain of Bacillus cereus Frankland and Frankland and Bacillus megaterium of Bary, and two strains of Bacillus pumillus Meyer and Gottheil promoted coleoptile growth.

KEY-WORDS: Bacillus; Triticum aestivum; tissue culture.
