近日,由比尔·盖茨(Bill Gates)创立的风险投资公司 Breakthrough Energy Ventures(BEV)领投了气候技术公司 1200 万美元的第二阶段种子轮。该公司也是 BEV 投资的第一家总部位于澳大利亚的公司。 本轮融资将用于加速 的商业化之路。两轮种子轮融资总额超 1700 万美元。Rumin8 董事总经理 表示第二阶段种子轮融资超额认购。 致力于设计从根本上减少农业甲烷排放的解决方案。该公司从芦笋藻(又称红藻,Asparagopsis,海门冬属)识别具有抗反刍动物消化产生甲烷特性的天然化合物,并以高效、低成本、可扩展和高质量的工艺复制它们,作为饲料添加剂喂养牲畜,以减少甲烷排放。 以支持引领世界实现净零排放的尖端公司为目的的 BEV 已经筹集了超过 2 亿美元的承诺资本,得到许多世界顶级商业领袖的支持。 “对可持续蛋白质的需求从未如此明显,这就是为什么BEV对减少牛肉和乳制品的甲烷排放非常感兴趣。”BEV 的 Carmichael Roberts 说,“ 提供了一个低成本、可扩展的工具箱,已被证明可以有效减少排放。我们的团队将支持 Rumin8 与农民密切合作,在全球范围内扩大该解决方案的覆盖范围。” 以慈善工作著称的亿万富翁 Andrew 和 Nicola Forrest 通过其农业食品业务 Harvest Road Group 参投;现有国际气候基金投资者、总部位于澳大利亚的 Aware Super Sentient WA Growth Fund 和美国的 Prelude Ventures 都在本轮中“增持”了股份。 Harvest Road 由 Forrest 家族拥有和经营,致力于使用创新的技术和方法来生产最优质的食品,拥有 Harvey Beef 和 Leeuwin Coast 品牌。其首席执行官 Paul Slaughter 表示, 补充了该集团在减少农业对气候变化影响方面的投资。“Harvest Road 支持多种新兴技术,重点是减少反刍动物的甲烷排放。饲料添加剂是我们减少碳足迹战略的重要支柱。” 作为反刍动物,牛具有将富含纤维的饲料转化为牛奶和肉类的独特能力。这要归功于在牛的瘤胃中发现的所有微生物。然而,正是这个消化饲料的过程导致甲烷的产生。生成甲烷的微生物称为产甲烷菌。近几十年来,人们投入了大量精力寻找减少牛甲烷排放的战略,畜牧业更是已被认作减少温室气体排放的关键参与者。 根据 2021 年发表在 Nature Reviews Microbiology上的综述文章“”,许多减少甲烷排放的策略直接针对甲烷菌群或甲烷本身——包括甲烷反应的抑制剂、直接影响甲烷菌、或去除甲烷。 其中,抑制类化合物用以抑制产甲烷途径的一个或多个酶步骤。然而一般来说,其有效性通常是暂时的,这可能由于适应和抗性机制。 不过,有两种化合物具有很好的应用前景:3-硝基氧基丙醇(3-NOP)和产含有多种卤代甲烷的大型藻类 Asparagopsis taxiformis。 前者被设计用于抑制甲基 CoM 还原酶(MCR)复合物,介导甲烷菌产甲烷途径的最后一步。在大多数研究中,3-NOP 作为食物补充剂,在不损害动物性能和健康的情况下,抑制甲烷作用高达 60%。 在体外瘤胃微生物群落中,后者导致甲烷产生量显著减少(95–99%);在不影响宿主体重的情况下,72 天的甲烷产量减少了 80%。 从芦笋藻中识别甲烷还原化合物后,凭借其独特优势——即受专利保护的技术,用以合成和稳定这些物质,并开发为饲料补充剂。 本轮融资之前, 依次推进了一些关键工作流程。“现在我们有资源并行推进它们,加快商业化之路。”这笔资金将用于澳大利亚、新西兰、巴西和美国的商业试验,产品品牌开发以及随着 Rumin8 走向其甲烷还原饲料添加剂商业化的试点工厂开发。“动物试验结果良好,且产品价格能够被市场接受。” 根据 最近所披露的消息,该公司已开始在新西兰对其甲烷还原饲料补充剂进行两项安全性和有效性试验。这些试验针对肉牛和奶牛,将使用不同的测量方法以在现场得到认可和验证。牛肉试验利用甲烷测量设施,提供超过 48 小时的连续测量,而乳制品试验利用绿色饲料系统,在整个试验期间测量甲烷排放,全天进行短时间爆发测量。 第一个试验是由 DairyNZ 在汉密尔顿进行的剂量反应试验。以牧草为主要日粮的哺乳期奶牛将每日摄取 3 次饲料补充剂、共摄取 45 次以上,以研究在基于牧场的系统中减少甲烷的潜力。 试验过程将密切监测动物健康,以验证产品的安全性。包括分析血液样本的动物健康标志物、监测行为并测量每天的采食量;该公司还将进行进一步的测量和分析,包括甲烷产量、甲烷强度(每公斤牛奶中的甲烷)、牛奶产量、牛奶成分、饲料转化率、采食量以及牛奶和组织中的饲料补充剂残留量。 使用奶牛小母牛的牛肉试验将由新西兰反刍动物甲烷测量中心所在的北帕默斯顿的 AgResearch 进行。 该试验将为牛提供四种剂量的甲烷还原饲料添加剂,以确定所需的最低有效剂量。 的产品将与少量颗粒混合,而主要的饮食成分将是新鲜切割的牧草。 在试验结束时,小母牛将在甲烷测量设施中度过 48 小时以连续测量甲烷产量,以及收集活重和血液和组织样本进行分析。 表示,新西兰一直是该公司的目标市场。“这些试验将确保我们对新西兰乳制品和牛肉生产系统中甲烷还原饲料添加剂的安全性和有效性充满信心。” 目前 正在澳大利亚和巴西进行其他试验。 巴西是世界上数量最大的肉牛所在地。该公司已与圣保罗州立大学(UNESP)签署了一项试验协议,在以牧场为主的放牧系统中进行广泛的基于牛群的试验。该试验于 2022 年底开始,为期 130 天。 的饲料添加剂将通过市售的矿物质补充剂混合,供牛食用。 2022 年,该公司还将足迹扩展到美国,在旧金山开设了办事处。气候技术的投资格局正在迅速扩大,旧金山湾区被列为吸引风险投资的全球五大投资中心之一,为 提供了更多机会。 与 相似,从 CSIRO(澳大利亚联邦科学与工业研究组织)分拆的 公司也由 Harvest Road 支持,并使用芦笋藻来抑制甲烷。但 FutureFeed 直接以芦笋藻为饲料,Rumin8 则无需生产海藻,而是通过实验室生产来自芦笋藻的有效化合物来供应农民。 0.05),表明符合孟德尔遗传定律的单个遗传因子控制了gfd1的灌浆期。此外,籽粒宽度和长度以及每穗粒数与籽粒灌浆期完全相关,表明 gfd1
