Palm oil is everywhere. It's in food, cosmetics and biofuels. It's in 50% of our supermarket products. Palm oil is unique in the vegetable oil market; it melts in your mouth, is great for cooking and is a high-yielding crop. However, palm oil is one of the biggest carbon emitters due to loss of tropical rainforest and peatland to make way for plantations - it contributes over 500 million tonnes of CO2e, over 1% of global emissions, from 19 million hectares of tropical land. It has caused significant habitat loss, including for the Orangutan and Sun Bear, and all too often the smallholders do not receive a fair price for their produce.The UK Government has committed to reaching Net Zero by 2050; 20% of UK emissions stem from agriculture and the food supply chain and these emissions must be tackled if we are to reach these targets.Sun Bear Bioworks is using precision fermentation to make an alternative to palm oil. We are optimising a yeast strain that naturally produces oil, in order to create our oil from food waste quickly and efficiently. Our process saves 5.7kg CO2 and 2000m2 land for every kg of palm oil - a saving in both cases of 80%. We are working with Evolutor on this project to optimise our strain's ability to process low-grade, sustainable feedstocks. Feedstock accounts for most of our process cost at scale, and finding a scalable sugar alternative is vital if we are to create maximum environmental impact. This builds on the work we carried out as part of our Fast Start award, project 10045430 "Alternative feedstock for precision fermentation of oil", which has allowed us to prove expression of key enzymes in our yeast strain for the metabolism of starch.

棕榈油无处不在。它在食品，化妆品和生物燃料中。这是我们50％的超市产品。棕榈油在植物油市场上是独一无二的。它在您的嘴里融化，非常适合烹饪，是一种高产的作物。然而，由于热带雨林和泥炭地的损失，棕榈油是最大的碳发射量之一，为人工林腾出了空间 - 它贡献了超过5亿吨的二氧化碳，超过1％的全球排放量，比1900万公顷的热带土地贡献。它造成了巨大的栖息地损失，包括猩猩和太阳熊，而且小农通常没有获得公平的价格。如果要达到这些目标，则20％的英国排放源于农业和食品供应链，并且必须解决这些排放。SunBear Bioworks使用精确发酵来替代棕榈油。我们正在优化一种自然产生油的酵母菌菌株，以便快速有效地从食物中产生油。我们的过程为每公斤棕榈油节省了5.7千克二氧化碳和2000平方米的土地 - 在两种情况下，这是80％的节省。我们正在与Evolutor合作，以优化应变能够处理低级，可持续原料的能力。原料占我们大部分流程成本的规模成本，如果我们要产生最大的环境影响，找到可扩展的糖替代品至关重要。这是基于我们作为快速启动奖的一部分，即10045430的“替代原料进行精确发酵”的工作，这使我们能够证明在酵母菌菌株中表达关键酶的淀粉代谢。
