摘要

Abstract <section xml:id="bit26710-sec-0001" numbered="no"> > Acetic acid is an abundant material that can be used as a carbon source by microorganisms. Despite its abundance, its toxicity and low energy content make it hard to utilize as a sole carbon source for biochemical production. To increase acetate utilization and isobutanol production with engineered Escherichia coli , the feasibility of utilizing acetate and metabolic engineering was investigated. The expression of acs, pckA , and maeB increased isobutanol production by up to 26%, and the addition of TCA cycle intermediates indicated that the intermediates can enhance isobutanol production. For isobutanol production from acetate, acetate uptake rates and the NADPH pool were not limiting factors compared to glucose as a carbon source. This work represents the first approach to produce isobutanol from acetate with pyruvate flux optimization to extend the applicability of acetate. This technique suggests a strategy for biochemical production utilizing acetate as the sole carbon source. </section> </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display:

Acs,Pcka </ i>和 Maeb </ i>的表达增加了脱丁醇产量,高达26%,加入TCA循环中间体表明中间体可以增强异丁醇生产。对于醋酸盐的异丁醇生产,与葡萄糖作为碳源相比,醋酸乙酸碱基和NADPH池没有限制因子。该作品代表了生产丙酮酸助焊剂优化的醋酸异丁醇的第一种方法,以延长乙酸酯的适用性。该技术表明,利用醋酸盐作为唯一碳源的生物化学生产策略。 </ p> </ section> </
