Sustainable, localised Farm-based microalgal fermentation to transform protein supplements for animal feedstock

17Cicada期待着一种革命性过程的发展，它将允许个体农场以可持续、成本效益高、对环境影响最小的方式独立生产自己的动物饲料。cicada旨在创造一种强大而创新的方法，利用废水来支持营养微藻的生长，这些微藻可以转化为高质量的动物饲料。预计到2050年全球人口将达到98亿，2100年将达到112亿（联合国），这大大增加了粮食生产的压力。全球事件，如乌克兰战争，对动物小麦饲料的成本产生了重大影响，去年增加了26.5%。这对食品通胀产生了影响，英国的食品通胀已上升至13%，加剧了当前的生活成本危机。为了向世界不断增长的人口提供粮食，必须大幅增加作物产量，以支持畜牧业生产。不幸的是，可耕地和淡水的可用性是有限的。预计到2030年，气候变化还将影响玉米和小麦的产量，玉米产量将减少24%，小麦产量将减少17%。微藻是解决这个问题的一个令人兴奋的方法。微藻蛋白质含量高（约75%），对氮和磷酸盐的利用效率高。这与传统的农业蛋白质生产形成鲜明对比，后者导致氮和磷酸盐流失，导致湖泊和河流污染以及海洋酸化。微藻生产蛋白质时，几乎所有的氮和磷酸盐都转化为蛋白质，对环境的影响最小。**我们的愿景是可持续生产以微藻为基础的动物饲料**，这将极大地帮助养殖业提高产量和降低成本。我们设想一场革命，我们的简单而创新的光生物反应器由农场操作，产生很少或不产生废物，修复农业废水，消耗二氧化碳生产动物饲料的微藻。**我们的主要目标**涉及分离快速生长的微藻菌株，这些菌株具有良好的营养特性，能够利用废水生长。我们还将专注于优化我们的光生物反应器技术，与现有的农场基础设施无缝集成，再加上强大的技术经济分析。我们的创新是首次尝试生产工业微藻菌株，利用农业废水预先优化生长，以可持续和具有成本效益的方式生产高质量的动物饲料。

17Cicada anticipates the development of a revolutionary process that will allow individual farms to independently produce their own animal feed in a way that is sustainable, cost effective and with minimal environmental impact. 17Cicada aims to generate a robust and innovative way of utilising wastewater to support the growth of nutritional microalgae that can be converted into high quality animal feed.The global population is predicted to reach 9.8 billion by 2050 and 11.2 billion in 2100 (UN), significantly increasing the pressure on food production. Global events, such as the war in Ukraine, have had a significant impact on the cost of animal wheat feed, which has increased by 26.5 % over the last year. This has impacted on food inflation, which has risen to 13 % in the UK, compounding the current cost-of-living crisis. To provide food for the world's growing population, a significant increase in crop production is necessary to support livestock production. Unfortunately, the availability of arable land and fresh water is limited. Climate change is also predicted to affect the production of both maize and wheat by 2030, reducing maize crops by 24 % and wheat crops declining by 17 %.Microalgae are an exciting solution to this problem. Microalgae have a high protein content (\>75 %) and are highly efficient in their utilisation of nitrogen and phosphate. This contrasts with conventional agricultural protein production, which results in nitrogen and phosphate run off, leading to pollution of lakes and rivers as well as ocean acidification. With microalgae protein production almost all the nitrogen and phosphates are converted to protein with minimal environmental impact.**Our vision is the sustainable production of microalgae-based animal feed** which will significantly help the farming industry to increase production and reduce costs. We envisage a revolution where our simple but innovative photobioreactors are operated by the farm, producing little or no waste, remediating agricultural wastewater and consuming carbon dioxide to produce microalgae for animal feed.**Our key objectives** involve the isolation of fast-growing microalgae strains with excellent nutritional profiles capable of growth using wastewater. We will also focus on optimising our photobioreactor technology to integrate seamlessly with existing farm infrastructure, coupled with robust techno-economic analyses.**Our innovation** is a first-of-a-kind attempt to produce industrial microalgae strains pre-optimised for growth using agricultural wastewater to produce high-quality animal feed in a way that is sustainable and cost effective.
