产氢菌株阪崎肠杆菌的筛选及其产氢特性的研究

Abstract

能源危机与环境污染问题受到人们越来越多的关注，开发新的能源体系已成为世界各国的共识。氢由于其本身无色、无嗅、无毒且燃烧后仅生成水而被认为是理想的清洁能源。另外，氢的能量密度高，其热值为143MJ/kg，约为石油热值的3倍；它能以气态、液态或固态金属氢化物的形式储存，能满足储运及各种应用环境的不同要求。因而“氢经济”成为各国经济发展规划的重要组成部分。 本研究对高温环境的样品进行分离，通过初筛和复筛，选出一株产氢性能稳定且活性较高的菌株。通过对菌株的形态结构、生理生化特征及16SrRNA基因序列进行分析，鉴定该菌株为阪崎肠杆菌（Enterbactersakazakii）。分析了pH值、碳源、菌...

As the economy develops, the energy source problem and the environmental issue are paid more and more attention. Developing new energy system has become basic. Many of the countries are concerning about the development of the new energy system. Hydrogen energy has been considered as one of the most ideal future energies as it is clean, pollution-free, high heat value and easily storage and transpo...
