Abstract

ALVAREZ-VERA, Manuel et al. Potential of the flora of the province of Azuay (Ecuador) as a source of beneficial microorganisms. Scientia Agropecuaria [online]. 2018, vol.9, n.4, pp.561-568. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2018.04.12.

The potential of vegetal species of the province of Azuay Ecuador for the obtaining of beneficial microorganisms was studied. In different altitudinal floors, samples of plants were collected from which, under laboratory conditions, colony-forming units (CFU.ml-1) were isolated and determined. In addition, either by biochemical tests or 16S-PCR amplification, the main microorganism’s beneficial potential for agriculture, the environment and industry were identified. It was established that the plant of altamisa (Artemisia vulgaris) with 5.43 X 106 CFU.ml-1 presents the best potential for CFU of yeasts, in the rue plant (Ruta graveolens L.) with 1.46 X 107 CFU. ml-1 was determined the largest number of CFU of Bacillus spp., for Lactobacillus spp., the coffee plant (Coffea arabica L.) with 2.31 X 1013 CFU.ml-1 presented the highest potential, the plant of rosemary (Rosmarinus officinalis) with 1.60 X 105 CFU.ml-1 was the one that showed the highest amount of CFU of actinomycetes; the beneficial microbial load present in each plant sample was identified. It is concluded that according to their characteristics and geographic location each plant species has a certain potential for Bacillus spp., yeasts, Lactobacillus spp. and actinomycetes
