Seaweed extracts have proven to be very effective plant bio-stimulants, with a breadth of scientific data underlying the identification of their active components and underlying mechanisms. There are numerous seaweed-derived products on the market globally, with the majority produced by an extraction method that also produces an alkaline by-product of limited use as fertilizer. A considerable volume of this insoluble alkaline fraction exists, and is largely comprised of macroalgal cell wall polysaccharides, which have been shown to have plant and animal health stimulatory properties. However, as these polysaccharides are insoluble in water, they are largely unavailable to most plants, but do provide a suitable growth media for less desirable microorganisms which can in fact interfere with plant growth. This project will investigate biological methods of increasing the bioavailability of these polysaccharides to valorize this currently unmarketable by-product for potential use in promoting plant growth and animal health, thereby adding a second value stream for companies engaged in production of seaweed extracts.

事实证明，海藻提取物是非常有效的植物生物刺激物，并具有大量的科学数据 鉴定其主动组成部分和潜在机制的基础。有很多 全球市场上的海藻衍生产品，大部分是由提取方法生产的 产生有限用作肥料的碱性副产品。大量不溶的碱性 存在分数，并且在很大程度上由大藻细胞壁多糖组成，这已被证明 具有动植物健康刺激特性。但是，由于这些多糖不溶于水，因此 它们在大多数植物中都无法获得，但确实提供了合适的增长媒体 实际上可能干扰植物生长的微生物。该项目将研究生物学方法 增加了这些多糖的生物利用度以使目前无法售出的副产品的价值 在促进植物生长和动物健康方面的潜在用途，从而为公司增加了第二个价值流 从事海藻提取物的生产。
