The broader impact/commercial potential of this Small Business Innovation Research Phase I project is to scale up the production of low-cost, low-energy novel materials to allow more water recycling and reuse, preserving this precious resource for society. The aims of the project are to increase scientific and technological understanding of advanced material design with a detailed knowledge of biodegradation to specifically and efficiently remove problem chemicals from water systems. In some cases, the water may be made suitable for municipal use. In other cases, water may be restored to a level such that it can be used for agriculture or industrial processing. The technical objectives of this Phase I research project are to design, construct and test encapsulated microbial materials that are targeted toward eliminating hard-to-remove or acutely hazardous chemicals from waters, so as to allow their reuse. The encapsulating material of silica is generally regarded as safe (GRAS), is inexpensive, and flexible. The materials are combined with specific microbial biocatalysts that are demonstrated to have broad biodegradation activities against a range of chemicals within specific chemical classes. One such class are the polycyclic aromatic hydrocarbons (PAHs) and related aromatic ring chemicals that include demonstrated toxins, carcinogens and endocrine disruptors. The technology to be developed, unlike some existing technologies currently in use, will seek to completely destroy the compounds of concern such that no waste material need to further treated or disposed of. Moreover, the specificity of the biocatalysts can be used to, in some cases, selectively remove chemicals of concern while completely retaining other chemicals that may be needed for the further utility of the water. Overall, the present project seeks to expand the use of biocatalysts and advanced materials to selectively and completely remove chemicals from water, thus minimizing cost and maximizing conservation and use of water resources.

该小企业创新研究第一阶段项目的更广泛影响/商业潜力是扩大低成本、低能耗新型材料的生产规模，以实现更多的水回收和再利用，为社会保护这一宝贵资源。该项目的目的是通过详细的生物降解知识，提高对先进材料设计的科学和技术理解，以专门有效地去除水系统中的问题化学品。在某些情况下，水可以适合市政使用。在其他情况下，水可能会恢复到可用于农业或工业加工的水平。该第一阶段研究项目的技术目标是设计、构建和测试封装的微生物材料，旨在消除水中难以去除或极其危险的化学物质，从而使其能够重复利用。二氧化硅封装材料通常被认为是安全的 (GRAS)、廉价且灵活。这些材料与特定的微生物生物催化剂相结合，经证明对特定化学类别内的一系列化学品具有广泛的生物降解活性。其中一类是多环芳烃 (PAH) 和相关的芳环化学物质，其中包括已证明的毒素、致癌物和内分泌干扰物。与目前使用的一些现有技术不同，即将开发的技术将寻求完全破坏所关注的化合物，从而不需要进一步处理或处置废料。此外，在某些情况下，生物催化剂的特异性可用于选择性地去除所关注的化学物质，同时完全保留进一步利用水可能需要的其他化学物质。 总体而言，本项目旨在扩大生物催化剂和先进材料的使用，以选择性和完全去除水中的化学物质，从而最大限度地降低成本并最大限度地保护和利用水资源。
