Keltsmaht Kelp is a First Nations led company specializing in premium and organic kelp products, based in the heart of The Nuu-Chah-Nulth Hahoulthee (Territory), also known as the greater Tofino area of British Columbia. Camosun Innovates is the applied research group at Camosun College and has been actively involved in advanced manufacturing and product development over the past twenty years, with a focus on assisting local companies with product development or quality issues associated with manufacturing. All of their kelp, Macrocystis integrifolia, is sustainably hand-harvested off the pristine coast of Clayoquot Sound and hand-processed in Tofino, BC. Their harvest license is based off of current research in Clayoquot Sound. Their main product, Kelp Probiotic, is an organic biostimulant made from wild kelp that has demonstrated great success for large scale fruit and vegetable growers, home gardens and small-scale growers, as well as lawn and indoor use. This product significantly increases crop performance and yield by: increasing vegetative growth and fruit enlargement due to the presence of highly concentrated natural phyto-hormones; accelerating crop metabolism and stimulating fast recovery from stress conditions, due to the presence of Laminariales, vitamins, betaines, mannitol and other polysaccharides, and; producing carrier effect on nutrients with alginic acid and mannitol that act as complexing agents enhancing nutrients uptake into the plant. The company's previous research and development work includes creating novel processing techniques, testing and creating multiple successful formulas, and implementing novel packaging. Currently, research is needed to optimize fermentation rate by studying the sugar substrate, the bacillus culture, and the kelp feedstock; this will greatly affect how Keltsmaht Kelp moves forward; decreases fermentation time will allow increases in production output. Plant biostimulants work to build healthy soil and plants through numerous mechanisms such as increasing the soil organic matter content by adding in humic and fulvic acid. There is also an increase in the beneficial microflora such as Rhizobium bacteria which can act as a biopesticide and biofertilizer. Seaweed based products can feed the soil with micro and macronutrients and buffer the pH. In general it is well documented that fermented materials contain significant nutrients and are suitable as a fertilizer for agriculture. Developing and refining production processes will allow the company to scale at a faster rate and ultimately introduce more locally-made agriculture products into the Canadian agriculture sector. The main research challenge to address is the impact of brown sugar vs unsulphured molasses on the fermentation process. Main deliverables include improved understanding of fermentation rates when varying key parameters such as molasses vs brown sugar, which is the substrate for fermentation. Other areas of inquiry include the quantity of starting culture as well as the chopping of the kelp. Lastly, obtaining a detailed chemical analysis profile for each of the fermentation experiments will allow decisions to be made regarding the best overall process. This research has value to other aspects of the business, Naas Foods, which is involved in kelp food and is working on a fermented kelp drink. This information could be used to refine the process and production of our future drink products.

Keltsmaht Kelp是一家原住民LED公司，专门从事高级和有机海带产品，总部位于Nuu-Chah-Chah-Nulth Hahoulthee（领土）的中心，也称为不列颠哥伦比亚省的大托菲诺地区。 Camosun Innovates是Camosun College的应用研究小组，在过去的二十年中一直积极参与先进的制造和产品开发，重点是协助当地公司与制造产品相关的产品开发或质量问题。他们的所有海带Macrocystis Integrifolia均在Clayoquot Sound的原始海岸上可持续地进行手工收获，并在不列颠哥伦比亚省Tofino进行了手工处理。他们的收获许可是基于当前在Clayoquot Sound的研究。他们的主要产品Kelp益生菌是一种由野生海带制成的有机生物刺激剂，在大型水果和蔬菜种植者，家庭花园和小规模的种植者以及草坪和室内使用方面取得了巨大成功。由于存在高度浓缩的天然植物激素，该产品通过以下方式显着提高农作物的性能和产量：增加营养生长和果实的增大；由于存在层状，维生素，甜菜碱，甘露醇和其他多糖，加速作物代谢并刺激从应力条件下快速恢复。用藻酸和甘露醇对养分产生载体作用，可作为络合剂，从而增强养分吸收植物。该公司以前的研发工作包括创建新颖的处理技术，测试和创建多个成功的公式以及实施新颖的包装。目前，需要研究来通过研究糖基质，芽孢杆菌培养和海带原料来优化发酵率。这将极大地影响Keltsmaht海带的前进方式。减少发酵时间将使产量增加。植物的生物刺激物通过多种机制（例如通过添加腐殖酸和富富酸增加土壤有机物含量）来建造健康的土壤和植物。 有益的菌群（例如根茎细菌）也有所增加，可以充当生物农药和生物肥料。 基于海藻的产品可以用微量营养素和大量营养素喂养土壤，并缓冲pH。通常，有充分的文献证明，发酵材料含有大量养分，适合作为农业的肥料。开发和完善生产过程将使公司能够以更快的速度扩展，并最终将更多本地制造的农业产品引入加拿大农业领域。要解决的主要研究挑战是红糖与未硫磺糖的影响对发酵过程的影响。主要的可交付成果包括在改变关键参数（例如糖蜜与红糖）时，对发酵速率的理解得到了改善，这是发酵的基板。其他查询领域包括起始培养物的数量以及海带的切碎。最后，为每个发酵实验获得详细的化学分析概况将允许就最佳总体过程做出决策。这项研究对业务的其他方面Naas Foods具有价值，该公司参与海带食品，并正在制作发酵海带饮料。这些信息可用于完善我们未来饮料产品的过程和生产。
