Screening and characterization of Sphingomonas sp. mutant for welan gum biosynthesis at an elevated temperature.

Bioprocess and biosystems engineering - 1 Sept 2014

Zhu Ping, Chen Xiaoye, Li Sha, Xu Hong, Dong Shuhao, Xu Zongqi, Zhang Yu

Abstract excerpt

The optimal temperature for the microbial polysaccharide fermentation is no higher than 30 °C, which is economically undesirable due to additional cooling cost. To solve this problem in the case of welan gum production, we obtained the high-temperature-tolerant-producing strain, Sphingomonas sp. HT-1 by atmospheric and room-temperature plasma-induced mutation. Using HT-1, we obtained a concentration and 1 %...
