I-Corps: Industrial Enzymes from the Microbiomes of Household Insects

开发能够催化植物细胞壁材料（木质纤维素）高效转化为可发酵糖或高价值化学结构单元的酶是许多工业酶公司的重要目标。然而，目前用于植物细胞壁降解的酶在有限的条件下具有活性;例如，它们不能处理非常酸性或碱性的条件。该研究项目旨在确定可用于分解植物细胞壁等难降解材料的工业酶。这种酶可用于产生能量和修复污染。该项目旨在寻找在不同条件下具有活性的新酶，因此，最大限度地发挥作用。使用这些改进的酶将使工业过程更便宜，产量更高，效率更高。这项研究将导致概念验证，特别是从家庭昆虫的微生物组中生产至少一种商业相关的酶。该项目还将为至少两种类型的专利提供基础：1）从骆驼蟋蟀和皮蠹甲虫中分离木质纤维素酶的方法，以及2）在该项目过程中鉴定的重组酶的应用。I-Corps计划将使该团队能够寻求工业合作伙伴关系，以根据工业合作伙伴的需求和利益定制拟议的研究。在执行本提案中概述的研究目标时，该团队将首先有机会成熟开发一个分离和筛选平台，该平台旨在从家庭昆虫微生物组中识别微生物和酶，这些微生物和酶可用于生物技术/工业应用，并与目标技术公司建立关系。此外，拟议的研究还可以回答有关家庭昆虫的生态学，它们的微生物群以及这些昆虫用于降解和消化永久性家庭材料的酶的几个问题。

Developing enzymes that can catalyze efficient conversion of plant cell wall material (lignocellulose) to fermentable sugars or high-value chemical building blocks is an important goal of many industrial enzyme companies. However, the current enzymes being used for plant cell wall degradation are active under a limited set of conditions; they can't, for example, deal with very acidic or basic conditions. This research project seeks to identify industrial enzymes that can be used to break down hard-to-degrade materials such as plant cell walls. Such enzymes are useful in producing energy and in remediating pollution. This project seeks to find new enzymes that are active in diverse conditions and, as such, maximally useful. The use of these improved enzymes would allow industrial processes to be cheaper, higher volume and more efficient. This research will result in a proof-of-concept, specifically the production of at least one commercially relevant enzyme from the microbiome of household insects. The project will also result in providing the basis for at least two types of patents: 1) process of isolating lignocellulosic enzymes from camel crickets and dermestid beetles and 2) the application of recombinant enzymes identified in the course this project. The I-Corps program will enable the team to seek out industrial partnerships to customize the proposed research to the needs and interests of the industrial partners. In performing the research goals outlined in this proposal, the team will foremost have the opportunity to mature the development of an isolation and screening platform designed to identify microorganisms and enzymes from household insect microbiomes that have utility for biotechnological/industrial applications and to form relationships with target technology companies. In addition the proposed research could also answer several questions about the ecology of the household insects, their microbiota, and the enzymes used by these insects to degrade and digest permanent household materials.
