Bioconversion of Agroindustrial Waste in the Production of Bioemulsifier by Stenotrophomonas maltophilia UCP 1601 and Application in Bioremediation Process

Table 2

Full-factorial design used for the production of bioemulsifier by S. maltophilia UCP 1601 after 96 h of culture in medium containing 10% WSO. The tests were performed in triplicate and the media of emulsification index (EI) values were used as response variable.
