Fermentative manipulations of cell wall polysaccharides to enhance seaweed extract by-product value

海藻提取物已被证明是非常有效的植物生物刺激剂，有广泛的科学数据 以确定其活性成分和潜在机制。有很多种 海藻衍生产品在全球市场上销售，大部分产品是通过提取方法生产的，这种方法还 产生一种碱副产品，作为肥料使用有限。相当大体积的这种不溶性碱 组分存在，主要由大型藻细胞壁多糖组成，已被证明是 具有促进动植物健康的特性。然而，由于这些多糖不溶于水， 它们在很大程度上对大多数植物是不可用的，但确实为不太可取的植物提供了合适的生长介质 实际上会干扰植物生长的微生物。这个项目将研究生物学方法。 提高这些多糖的生物利用度，以使目前无法销售的副产品 在促进植物生长和动物健康方面的潜在用途，从而为公司增加第二个价值流 从事海藻提取物的生产。

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.
