Acadian Seaplants Ltd. (ASL) is a major seaweed harvesting, cultivation and processing company with operations throughout the Maritimes and, more recently, internationally. As a major activity in their plant division, ASL harvests rockweed (Ascophylum nodosum) and prepares a liquid extract for sale as a growth stimulant for plants. During this extraction process, a significant amount of solid waste (termed DNP) is produced. This DNP comes from a finite biological resource and it is suspected that it still contains important biomolecules. This project, a collaborative effort between the BTSC-CCNB and ASL, aims to maximize the use of this rare ressource, by investigating and ultimatly commercializing a value added product from this by-product. Although a lot of information is available for the fermentation of seaweed, very little information is provided for commercial scale fermentation of rockweed byproducts, characterization of the degradation of the matrix, sugar utilization, and nitrogen utilization during the fermentation process. A number of new microbial communities and strains were isolated during the course of a first project which have shown promise to break down DNP polysaccharides more efficiently. These microbial strains, including microbial communities, fungi and bacteria isolated from various sources, will be tested for their ability to hydrolyze polysaccharides and to release bioactive components. This initiative is of great value as it could, among other things, maximize the use of an exceptional resource, stimulate the emergence of new market niches and export markets in crop production and horticulture, as well as have a positive environmental impact in keeping waste streams from reaching landfills. It could also create employment in a coastal rural area of the Maritimes.

Acadian Sapplants Ltd.（ASL）是一家主要的海藻收获，耕种和加工公司，在整个海事中以及最近在国际上进行业务。作为其植物分裂的主要活动，ASL收获了岩藻（腹腔小肠），并准备出售液体提取物作为植物的生长刺激剂。在此提取过程中，产生大量的固体废物（称为DNP）。该DNP来自有限的生物学资源，怀疑它仍然包含重要的生物分子。该项目是BTSC-CCNB和ASL之间的合作努力，旨在通过调查和最终将此副产品的增值产品进行商业化，以最大程度地利用这种罕见的Ressource。尽管有很多信息可用于发酵海藻，但对于冰草副产品的商业尺度发酵，基质的降解，糖的利用率和氮利用的表征很少。在第一个项目的过程中，隔离了许多新的微生物群落和菌株，这些群落有望更有效地分解DNP多糖。这些微生物菌株，包括从各种来源分离出的微生物群落，真菌和细菌，将测试其水解多糖和释放生物活性成分的能力。该倡议具有巨大的价值，除其他外，它最大程度地利用了特殊资源，刺激了农作物生产和园艺中新市场的出现和出口市场的出现，并在防止废物流到达垃圾填埋场中产生了积极的环境影响。它还可以在海事的沿海农村地区创造就业。
