I-Corps: Production of the red carotenoid astaxanthin by marine copepod

这个I-Corps项目的更广泛的影响/商业潜力是桡足类（小型水生甲壳类动物）的基因工程菌株，该菌株可以大量生产天然红色类胡萝卜素，虾青素。虾青素是一种经济上特别重要的色素，用于水产养殖、营养品和化妆品工业。虾青素可以合成，但对天然来源的虾青素的需求越来越大。目前，用于水产养殖饲料的天然虾青素的市场价值约为2000美元/kg，天然虾青素的营养品市场价值约为15，000美元/kg。最近估计，2014年全球虾青素市场规模超过250吨，预计2016年至2023年的复合年增长率超过7%。这项技术为客户提供了两个主要好处：一是成本可能低于现有资源的天然虾青素来源，二是未来工程的潜力，以进一步提高虾青素产量并降低生产成本。这个I-Corps项目将探索海洋桡足类动物Tigriopus californicus的基因工程谱系的市场潜力，其天然虾青素产量比野生桡足类动物高出80%。桡足类是与虾有关的微小甲壳类动物，是海洋鱼类饮食的天然组成部分。这项技术是对目前来源的改进，因为桡足类可能以较低的生产成本生产更多的红色素，并且已经证明，增加虾青素产量的基因工程是可行的。这个I-Corps项目旨在通过客户发现访谈评估该技术的市场机会，这将导致客户反馈，从而更好地了解商业化的要求。此外，该项目有可能导致商业应用天然色素生产研究的重大进展。

The broader impact/commercial potential of this I-Corps project is a genetically engineered strain of copepods (small aquatic crustaceans) that hyperproduce the natural red carotenoid, astaxanthin. Astaxanthin is an especially economically important pigment used in the aquaculture, nutraceutical, and cosmetic industries. Astaxanthin can be made synthetically but there is increasing demand for naturally sourced astaxanthin. Currently, the market value of natural astaxanthin for aquaculture feed is approximately $2000/kg and the nutraceutical market value for natural astaxanthin is alomst $15,000/kg. Recent estimates of the global astaxanthin market size are at more than 250 tons in 2014 and a projected compound annual growth rate of over 7% from 2016 to 2023. This technology provides two main benefits to customers: a natural source of astaxanthin at a potentially lower cost than current sources and potential for future engineering to further increase astaxanthin production and reduce production costs.This I-Corps project will explore the market potential of genetically engineered lineages of the marine copepod Tigriopus californicus that produced up to 80% more natural astaxanthin than wild copepods. Copepods are tiny crustaceans related to shrimp and are natural component of marine fish diets. This technology is an improvement over the current sources because copepods potentially produce more red pigment at a lower production cost, and it has been demonstrated that genetic engineering for increased astaxanthin production is feasible. This I-Corps project aims to evaluate the market opportunities for the technology through customer discovery interviews that will result in customer feedback that provides a better understanding of the requirements for commercialization. Additionally, this project has the potential to lead to significant progress in research on natural pigment production for commercial applications.
