Abstract

The aim of the present study was to isolate autochthonous microorganisms with biosurfactants capacities from the rhizospere of the cotton (Gossypium spp.), cachanilla (Pluchea sericea) and salicornia (Salicornia bigelovii) in the Mexicali valley. The biosurfactant activity and biosurfactant productions by the strains isolated from the rhizosphere of the cotton (Bs-Alg), cachanilla (Bs-Cach) and salicornia (Bs-Cach01) were determined using oil spreading technique and emulsification activity with corn, olive, soybean and diesel oils, respectively. The analysis of the 16S rRNA showed that strains Bs-Alg, Bs-Cach and Bs-Cach01 are closely related among them and with respect to all Bacillus subtilis with more than 99% similarity values. Results showed that all strains had biosurfactant activity. However, Bs-Cach was the only strain that showed a significant biosurfactant activity with all the vegetable oils and diesel. Finally, the isolation of a biosurfactant producing Bacillus subtilis strain from native plants of Mexicali valley displayed a substantial potential for production of biosurfactants that can be applied to food industry.
