Kinetic study and modeling of biosurfactant production using Bacillus sp
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 e...

| description | 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. |
