Abstract

Anhydrobiotic engineering aims to improve desiccation tolerance in living organisms by adopting the strategies of anhydrobiosis. This was achieved for Escherichia coli and Pseudomonas putida by osmotic induction of intracellular trehalose synthesis and by drying from trehalose solutions, resulting in long-term viability in the dried state.

摘要

隐生工程旨在通过采用隐生策略提高生物体的耐旱性。通过渗透诱导细胞内海藻糖合成以及从海藻糖溶液中干燥,大肠杆菌和恶臭假单胞菌实现了这一点,从而在干燥状态下具有长期生存能力。
