| Summary: | Biosurfactants are surface active agents that been synthesized by microorganisms naturally. They are consisting of both hydrophilic and hydrophobic parts in their general structures which can decrease the surface tension between two distinct stages or the liquid interfacial tension between water and oil. By having this feature, these natural surfactant have proven that they are more advantageous compared to the synthetic surfactants. However, these compounds unable to beat synthetic surfactants in term of production cost. In order to boost the output of biosurfactants, there are several options that can be carried out such as developing more economical manufacturing method and use the cheaper substrates during the process. The use of raw materials from agro-waste, hydrocarbon or by-products of process is one of the alternatives in offering a culture medium with carbon sources and, at the same moment, can be cost-effective in generating the biosurfactants. From this research, the potential carbon sources were evaluated to be used in biosurfactant production. To achieve the purposes of experiment, a mixed integer linear programming (MILP) model was created to select the suitable carbon origin. The software General Algebraic Modeling System (GAMS) is chosen as an optimization instrument in developing the desired models. As a result of modelling, rhamnolipid is verified as the easiest biosurfactant to be produced. While, the soapstock is highly potential to be utilized as carbon source in synthesizing the biosurfactant. |
