Abstract

Nitrogen fixation of leaf surface of 12 species of Tillandsia was determined by ARA assay. The data showed that positive nitrogenase activity occurred on leaves put on enrichment cultures only. Bacillus and Pseudomonas were observed to be the predominant bacteria on the leaves, but other genera as Erwinia sp., Agrobacterium sp., Vibrio sp., Xanthomonas sp. and Rhanella sp. were found. Among all the isolates only Bacillus megaterium fixed nitrogen in pure culture.
