Isolation and Characterization of Biosurfactant-producing Alcaligenes sp. YLA11 and its Diesel Degradation Potentials

Abstract: This study aimed to isolate and identify biosurfactant producing and diesel alkanes degrading bacteria. For this reason, bacteria isolated from the diesel contaminated site were screened for their potential to produce biosurfactants and degrade diesel alkanes. Primary selection of diesel degraders was carried out by using conventional enrichment culture technique where 12 bacterial strains were isolated based on their ability to grow on minimal media supplemented with diesel as sole carbon source, which was fo… Show more

“…Predominance of this genus of bacteria is linked to its ability to utilize chromium as substrate, which helped it to thrive well in the environment [23]. The occurrence of other isolates of the genera Providencia, Salmonella, Enterobacter, Leminorella, Bacillus and Paenibacillus (Table 3) in tannery effluents has been previously reported [8,21,22,24,25]. Drop collapse test, oil spreading technique and Emulsification assay are indirect method used to screen biosurfactant production [22,26].…”
