Bioemulsification activity assessment of an indigenous strain of halotolerant Planococcus and partial characterization of produced biosurfactants

Abstract: Halotolerant bacteria are regarded as effective oil-scavengers in the polluted saltern and seawater. In this regard, a halotolerant Planococcus was isolated from oilcontaminated area of Dezful north springs, Iran, due to its capacity in biosurfactant (BS) production. To facilitate hydrocarbons degradation, in the current study, the efficiency of BS production as function of growth rate of the halotolerant Planococcus was investigated in the vicinity of heavy crude oil by emulsification index (E24).

“…Since only 0.02 % of CO is water soluble, there is a need for emulsification, which is necessary for improving the bioavailability of petroleum hydrocarbons to microorganisms by increasing the interfacial area between the water and the insoluble hydrocarbons [ 25 , 36 ]. Biosurfactant-producing bacteria can consume CO as the sole carbon and energy source in various different forms including soluble CO, very small CO droplets and large CO droplets.…”

“…Biochemical, morphological and 16S rRNA sequence analysis were conducted to identify the isolate. To amplify the 16S rRNA gene fragment, universal primers Fd1 (5′-AGAGTTTGATCCTGGCTCAG-3′) and Rd1 (5′-AGGAGGTGATCCAGCC-3′) were used and PCR process was programmed as described by Ebrahimipour et al [9]. The PCR product was sequenced by Sinagene Company (Tehran, Iran) and nucleotide sequence was edited by BioEdit software version 5.0.6 (Abbott company, Calsbad, CA, USA).…”

“…Biosurfactants as a green alternative are preferred over synthetic surfactants owing to their lower toxicity, higher biodegradability and great stability at different physiochemical conditions [9]. The capability of biosurfactants to reduce surface tension and form stable emulsions is a virtue for countless applications [10].…”
