Abstract

An integrated high-throughput screening (HTS) strategy was developed to screen large numbers of polymyxin E-producing mutants of Paenibacillus polymyxa. Various types of mutants were transferred onto the surfaces of solidified agar in 96-well microtiter plates, and then inoculated to 96-deep-well microtiter plates for micro-cultivation. The culture conditions were optimized for the production of polymyxin E. The supernatants from the micro-culture plates were transferred to 96-well bioassay microtiter plates containing Escherichia coli JM109 for high-throughput bioassay. By using this high-throughput screening (HTS) procedure, one best producer P. polymyxa PE 5.808 was identified from a large NTG mutated library with about 5,000 isolates. The volumetric productivity of polymyxin E of P. polymyxa PE 5.808 was 1,200 μg/ml in shake flasks, about 140% improvement compared with that of the wild type strain.
