通过生物技术对不可避免的食品供应链废物进行价值评估，将有利于循环经济的实施，并可能有助于通过降低原料成本提高最终产品的市场竞争力。对小麦粉磨后饲料、马铃薯加工废料和甜菜浆作为利用Starmerella bombicola生产槐糖脂的亲水性碳（葡萄糖）、氮和微量营养素的唯一来源的适用性进行了评估。虽然所有三种原料都可用于槐糖脂生产，但马铃薯废料是最有前途的原料，分批和补料分批生物反应器发酵的产物滴度分别为60.5和77.8 g/L。马铃薯水解物作为补料培养基的可行性也得到了证明，补料分批发酵的生产率比分批发酵提高了三倍。这预示着马铃薯水解物在未来更复杂的发酵方案中的使用，包括连续进料和原位分离。为了全面评估马铃薯废物作为发酵原料的可行性，使用英国作为案例研究进行了供应链建模。该模型确定了马铃薯废物工业规模发酵的理想地点，如英格兰西北部，东米德兰兹郡和苏格兰中部。该设施的规模极大地改变了供应链的复杂性，导致环境和财政成本发生重大变化。还讨论了实际加工考虑和对工艺技术经济的影响。所提供的见解将是有用的工业槐糖脂生产和工业生物技术的可持续原料的未来发展。
Valorization of unavoidable food supply chain waste via biotechnology would be beneficial to the implementation of circular economics and may help increase market competitiveness of the final product via reduced feedstock costs. The suitability of post-milling wheat feed, potato processing scraps and sugar-beet pulps to act as the sole source of hydrophilic carbon (glucose), nitrogen and micronutrients for sophorolipid production usingStarmerella bombicolawas assessed. While all three feedstocks were viable for sophorolipid production, potato scraps were the most promising feedstock, with product titers of 60.5 and 77.8 g/L from batch and fed-batch bioreactor fermentations, respectively. The viability of potato hydrolysate as a feeding media was also demonstrated, with a three-fold increase in productivity of fed-batch over batch fermentation. This bodes well for future use of potato hydrolysate in more sophisticated fermentation schemes involving continuous feeding and in-situ separation. To holistically evaluate the viability of the potato waste as fermentation feedstock, supply chain modeling was conducted using the UK as a case study. The modeling identified ideal locations for industrial scale fermentation of the potato waste, such as North-West England, East Midlands and Central Scotland. The scale of the facility was shown to greatly alter the complexity of the supply chain, leading to significant changes in environmental and fiscal costs. Practical processing considerations and the implication on process techno-economics are also discussed. The insights provided will be useful for future development of sustainable feedstock for industrial sophorolipid production and industrial biotechnology in general.
