Starmerella bombicola is the most productive strain known forSL production, with a volumetric productivity of up to 3.7 g/L.h (Wang et al.,2019). Recent sustainable development goals of food security, environmentalprotection, material and energy ef ciency are the key drivers for the valorizationof food waste. In the present work, the production of biosurfactant SLs fromseveral (food) waste streams was investigated. Food waste obtained from alocal restaurant was subjected to enzymatic hydrolysis for 16 h, yielding ahydrolysate containing about 100 g/L glucose and 2.4 g/L free amino nitrogen.The hydrolysate was subsequently used for SLs fed-batch fermentation andreached titer of 115.2 g/L in 92 h with an overall volumetric productivity of 1.25g/L.h (Kaur et al., 2019). Further improvement of fermentation system andstrategy has been developed using a semi-continuous integrated production-separation system. An average volumetric productivity of 2.43 g/L.h and anoverall SLs yield of 0.73 g/g was achieved within 240 h. Moreover, the potentialof sustaining high production ef ciency during long-term fermentation times(480 h) was investigated and an overall productivity and SLs yield of 2.39 g/L.hand 0.73 g/g were obtained, respectively (Wang et al., 2020a). This laboratoryexperiment was further evaluated with TEA simulation. It was found that themost pro table option led to high NPV (US$183,598,000), IRR (36.17%), ROI(43.87%) and payback years (2.28 years) (Wang et al., 2020b). It should bestressed that SLs price need to lower to allow SLs to penetrate the market.ReferencesWang et al., 2019. https://doi.org/10.1002/jctb.5847.Kaur et al., 2019. https://doi.org/10.1016/j.jclepro.2019.05.326.Wang et al., 2020a. https://doi.org/10.1016/j.jclepro.2019.118995.Wang et al., 2020b. https://doi.org/10.1016/j.biortech.2020.122852.1 2 1 34 5 3 611/19/2020 Submission Completedhttps://aiche.confex.com/aiche/foodie20/general/papers/index.cgi?username=617585&password=338048 2/4Session Selection:Global Food Challenges and their SolutionsTitle:Sophorolipid Production from Food WasteSubmitter's E-mail Address:carollin@cityu.edu.hkPreferred Presentation Format:Oral OnlyFirst Presenting AuthorPresenting AuthorHuaimin Wang Email: hwang236-c@my.cityu.edu.hk -- Will not be published City University of Hong Kong Hong Kong China Second AuthorGuneet Kaur Email: kaur.guneet07@gmail.com -- Will not be published York University Toronto ON Canada Third AuthorMing Ho To Email: minghoto@cityu.edu.hk -- Will not be published City University of Hong Kong Hong Kong China Fourth AuthorSophie L.K.W.
