“…On the other hand, the biosurfactant produced by C. lipolytica UCP 0988 that was investigated by Santos et al [40] removed 92.3% of the burned motor oil, and, in the study by Andrade et al [38], the biosurfactant produced by Candida glabrata removed 95.7% of the burned engine oil through the washing method.…”

“…The bioemulsifier produced by B. subtillis was tested for its potential to remove methylene blue dye (molecular mass −333.6 g/mol) according to the methodology proposed by Asku et al [38], modified by the use of the bioemulsifier to replace the chemical surfactant sodium dodecyl sulfate (SDS). The experiments were carried out in 250 mL Erlenmeyer flasks containing a methylene blue solution prepared from a standard solution (1 g•L −1 ) and the crude bioemulsifier (1 g•L −1 ), suspended in distilled water.…”

In this work, we investigated the potential of Bacillus subtilis UCP 0146 in the bioconversion of a medium containing 100% cassava flour wastewater to obtain a bioemulsifier. The evaluation of the production was carried out by the emulsification index (IE24) and the surface tension (ST). The ionic charge, stability (temperature, salinity, and pH measured by IE24 and viscosity), and ability to remove and disperse oil and textile dye were investigated. B. subtilis produced an anionic bioemulsifier in the medium containing 100% cassava wastewater under Condition 4 of the factorial design (inoculum 9% at a temperature of 35 °C and shaken at 100 rpm), and showed a surface tension of 39 mN/m, an IE24 of 95.2%, and a yield of 2.69 g·L−1. The bioemulsifier showed stability at different pH (2–8), temperatures (0–120 °C), and NaCl concentrations, a dispersion oil displacement area (ODA) test of 55.83 cm2, and a reduction of the viscosity of the burned engine oil (90.5 Cp). The bioemulsifier was able to remove petroleum (94.4%) and methylene blue azo dye (62.2%). The bioemulsifier and its synthesis from bacteria also emphasizes the role of surfactants in oil remediation.

“…The results obtained in this work suggest that the biomolecule produced by B. subtilis has characteristics of a bioemulsifier. According with Rahman, et al [39] the bioemulsifiers are characterized by not causing significant changes in the reduction of surface tension between liquids and high emulsifying activity.…”

Stability at different pH (2-8), temperatures (0-120ºC) and NaCl, dispersed (55.83 cm2-ODA) and reduced the viscosity of the burned engine oil (90.5 cP) , removed 94.4% petroleum and demonstrated efficiency in methylene blue removal (62.2%). The bioemulsifier and its synthesis from bacteria and also emphases on the role of surfactants in oil remediation.

“…Biosurfactants, which for a long time have been confused with bioemulsifiers, derived their name from biologically produced surfactants (Rahman and Randhawa, 2015). They play a primary function, facilitating microbial presence in environments dominated by hydrophilichydrophobic interfaces (Paniagua-Michel et al, 2014).…”

The study was carried out to compare the the production capabilities and the biosurfactant activity of the bacteria, Bacillus subtilis and Pseudomonas aeruginosa using engine oil and diesel as the substrates respectively. The test organisms were isolated from engine oil contaminated soil as in the case of the Bacillus subtilis, which was collected from an automobile workshop in Samaru, Zaria and hydrocarboncontaminated water in the case of the Pseudomonas aeruginosa. The medium used for the experiment was a mineral medium supplemented with 2% engine oil and 2% diesel as the sole source of carbon and energy for Bacillus subtilis and Pseudomonas aeruginosa respectively. Production of biosurfactant was assayed by monitoring the increase in cell concentration, biosurfactant concentration, emulsification index and decrease in surface tension. Highest level of cell concentration and biosurfactant concentration (3.3 x 10 8 CFU/ml and 0.0106mg/ml respectively) were obtained at 144 h for the Pseudomonas aeruginosa using diesel as source of carbon and energy while the highest level of cell concentration and biosurfactant concentration (3.2 x 10 8 CFU/ml and 0.0096mg/ml respectively) were obtained at 120hrs for the Bacillus subtilis using engine oil as source of carbon and energy. The research show that Pseudomonas aeruginosa using diesel as the sole source of carbon and energy is better for the production of biosurfactant than Bacillus subtilis using engine oil as the sole source of carbon and energy.
