英文摘要	Dietzia spp. have broad potential applications in industries. However, genetic manipulation of these species is obstructed by their low transformation efficiency, which is in the range of 10(4) colony-forming units (CFU) mu g(-1) exogenous DNA. In this study, both single-factor and orthogonal experiments were conducted to test the effects of competent cell concentration (parameter A), electroporation time (B), and field strength (C), as well as the concentrations of glycine (D), isonicotinic acid hydrazide (INH, E), Tween 80 (F), and penicillin G (G) on the electrotransformation efficiency of Dietzia sp. DQ12-45-1b. The order in which the parameters contributed to electrotransformation efficiency was C>D>F>G>B>A>E, suggesting that field strength, glycine, and Tween 80 each had a greater capability to increase electrotransformation efficiency than the other parameters tested. Using the optimized protocol deduced from the results of the orthogonal experiments, the electrotransformation efficiency of Dietzia sp. DQ12-45-1b reached 2.51 x 10(7) CFU mu g(-1) plasmid. To the best of our knowledge, this is the highest transformation efficiency that has been reported for Dietzia bacteria to date. Thus, we present a method that combines the transformation factors to obtain the optimal transformation efficiency for a target bacterium. (C) 2014 Elsevier B.V.
