The project aims to translate existing academic research to enable the production of interpenetrating network (IPN) gels of starch and nanocellulose fibres using side-by-side enzymatic and/or bacterial synthesis routes. These IPN gels will be produced with the end aim of use in the food and home care industries. The project will develop tandem enzymatic processes for the production of small fragments of starch, xyloglucan and cellulose, assembly of components into gels in the presence of water, and characterisation of the mechanical and physical properties of the gels. We will valorise waste, making new products, reducing costs and CO2 emissions for the companies we will support through this technology. Industrial input will guide development of the gels, targetting key industrial applications. No research has yet developed gels based on industrial biotechnology approaches to produce small molecules of starch combining them with cellulose fibrils.

该项目旨在转化现有的学术研究成果，使淀粉和纳米纤维素纤维的互穿网络（IPN）凝胶的生产能够使用并行酶和/或细菌合成路线。这些IPN凝胶将以用于食品和家庭护理行业的最终目的而生产。该项目将开发用于生产淀粉、木葡聚糖和纤维素小片段的串联酶促工艺，在有水的情况下将组分组装成凝胶，并表征凝胶的机械和物理特性。我们将通过这项技术为我们支持的公司减少废物，制造新产品，降低成本和二氧化碳排放。工业投入将指导凝胶的开发，目标是关键的工业应用。还没有研究开发出基于工业生物技术方法的凝胶，以生产小分子淀粉，将其与纤维素原纤维结合。
