Abstract
Total aerobic heterotrophs and N2-fixing putative azospirilla associated with rice plant grown in long-term unfertilized wetland rice field at 5 sites in the Philippines were enumerated. Several azospirilla isolates were identified based on cellular morphology, biochemical tests and reaction to immunodiffusion. Azospirilla constitute about one percent of the total aerobic heterotrophs. Most (85%) of the Azospirillum isolates belong toA. lipoferum indicating its preferential colonization to the rice plant.
