SBIR Phase I: Microbial Enhancement of Soybeans for Salmonid Diets

这个小企业创新研究第一阶段项目旨在开发微生物增强植物蛋白来替代水产养殖饲料中的鱼粉。 环境问题和商业限制使得用植物蛋白替代鱼粉成为水产养殖业的长期目标。 大豆中的非营养性碳水化合物代表了使用微生物处理来提高大豆蛋白质的特别困难的技术挑战。 为了应对这一挑战，该项目提出将快速、多标准菌株分离和筛选、固体基质培养技术和鲑鱼饲料配方方面的创新联合收割机结合起来。第一阶段项目的主要任务是证明选择微生物以满足多个标准的技术可行性，开发固体基质培养工艺，并将增强的大豆纳入鳟鱼饮食。该项目的商业应用是在水产养殖领域。 一种满足国内鳟鱼业和政府孵化场要求的植物蛋白可以立即在商业上应用，取代大约25 000吨鱼粉。据预测，2010年全世界水产养殖将消耗约280万吨鱼粉，商业价值超过15亿美元。一种增强的植物蛋白可以占据这个市场的很大份额。

This Small Business Innovation Research Phase I project aims to develop microbially enhanced plant protein to replace fishmeal in aquaculture feeds. Environmental issues and commercial constraints make substituting plant protein for fishmeal a long standing goal of the aquaculture industry. Non-nutritive carbohydrates in soybeans represent a particularly difficult technical challenge in using microbial treatment to enhance soy protein. To address this challenge, this project proposes to combine innovations in rapid, multi-criteria strain isolation and screening, solid substrate culture technology and salmonid diet formulation. The principle tasks of this Phase I project are to demonstrate technical feasibility of selecting microbes to meet multiple criteria, to develop solid substrate culture processes, and to incorporate enhanced soy into trout diets. The commercial application of this project is in the area of aquaculture. A plant protein meeting requirements of the domestic trout industry and government hatcheries could find immediate commercial application in displacing approximately 25,000 tons of fishmeal. Worldwide aquaculture is forecast to consume about 2.8 million tons of fishmeal in the year 2010 with commercial value in excess of $1.5 billion. An enhanced plant protein could capture a significant share of this market.
