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.
