Background
Surfactants are one of the most important raw materials used in various industrial fields as
emulsifiers, corrosion inhibitors, foaming agents, detergent products, and so on. However,
commercial surfactant production is costly, and its demand is steadily increasing. This study
aimed to evaluate the performance of typical strains of Bacillus sp. to produce biosurfactants
through fermentation. It also included the investigation of the effect of initial glucose
concentration and the carbon to nitrogen ratio.
Results
The biosurfactant yield was in the range of 1–2.46 g/L at initial glucose concentrations of 10–
70 g/L. The optimum fermentation condition was achieved at a carbon to nitrogen ratio of 12.4,
with a decrease in surface tension of up to 27 mN/m.
Conclusions
For further development and industrial applications, the modified Gompertz equation is
proposed to predict the cell mass and biosurfactant production as a goodness of fit was
obtained with this model. The modified Gompertz equation was also extended to enable the
excellent prediction of the surface tension. |
