The prospect of tailoring the process conditions in mixed culture fermentation is attractive since it can produce a predominance of a target VFA without the need for a sterile, pure culture-based process. Among VFAs, butyric acid has a wide range of industrial applications which are currently met by chemical synthesis. This study showed a targeted production of butyric acid in a mixed culture VFA fermentation under psychrophilic temperature. Compared to mesophilic conditions, the butyric acid produced at 17°C accumulated to up to 7 days at 0.5 g/L compared to in 37°C where it was not detected after day 1. The microbial community study showed the increased abundance of <em>Sporosarcina</em> and <em>Solibacillus</em> genus which degrades proteins, aiding the <em>Clostridium_sensu_stricto</em> spp. in producing butyric acid potentially through protein degradation. Within the detected bacterial diversity showing a lower Shannon index of 0.84 at 17ºC, these genera also showed a higher abundance. For further enhancing the hydrolysis, thermal-alkaline pretreatment of food waste was performed. However, it reduced the subsequent production of butyric acid as compared to untreated food waste. Under 17ºC, butyric acid’s concentration was 0.06 g/L, while at 37ºC, it was 0.12 g/L. This showed that intrinsic microflora of food waste was essential for its production.

This study focuses on the strategic planning and tactical management problem of a regional biomass supply chain system with multiple feedstock and final products. A novel SVC-based data-driven robust optimization model is developed to provide the tradeoff solutions under uncertainties. Compared with the traditional robust optimization model, it can better depict the uncertain sets, reduce data redundancy, and provide less conservative strategies for decision makers according to their risk preferences. The proposed model is validated through a case study, Meizhou city in China. The results suggested the optimal investment scale and site for biorefineries and biomass power plants at the strategic planning level, as well as the feedstock supply network, inventory management, and production arrangement at the tactic management level. The optimal robust solutions can be derived by varying the envelope level of the uncertain sets. Moreover, sensitivity analysis is performed to investigate the influences of the variations of key parameters. It is found that the produced bioethanol and electricity lack cost advantages in the current situation, even with a 30 % reduction in main cost parameters. Insufficient biomass yield may require extra capital investment to satisfy bioenergy demand but with a higher supply cost.
