Development of new seaweed based plant biostimulant products and understanding their mode of action

Plant biostimulant is a new class of agricultural input that has gained importance and wide acceptance in the last few years. Acadian Seaplants Limited, a marine biotechnology company, manufactures liquid and powdered Ascophyllum nodosum extract plant biostimulants. To maintain the leadership in plant biostimulants ASL has embarked on developing new A. nodosum based biostimulatns. This project will focus on new product development by adopting novel seaweed processing technologies, creating blends of seaweed extracts and functional ingredients.

Application, efficacy and scale up of a novel extraction method for valorization of by-products of Ascophyllum nodosum extract processing

The industry partner is a producer of a successful seaweed based plant product used globally to improve plant growth. However, a large amount of waste byproduct, termed seaweed insoluble residue, is created as a byproduct of the production process. This residue has been found to contain a large amount of the original seaweed biomass. By extracting this unused biomass from the product, it is possible to turn a current waste stream into a marketable product. The proposed project will make use of ultrasound processing to improve the solubility of the SIR.
