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.

该项目旨在将现有的学术研究转化为能够使用并排的酶和/或细菌合成路线生产淀粉和纳米纤维素纤维的互穿网络（IPN）凝胶。生产这些IPN凝胶的最终目的是用于食品和家庭护理行业。该项目将开发串联酶促工艺，用于生产淀粉、木葡聚糖和纤维素的小片段，在有水的情况下将成分组装成凝胶，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将支持的公司创造价值，制造新产品，降低成本和二氧化碳排放。产业投入引导凝胶发展，瞄准重点产业应用。目前还没有研究开发出基于工业生物技术方法的凝胶，将小分子淀粉与纤维素纤维结合在一起。
