Abstract

R300B-, RSF1010-, and RK2-derived plasmids were introduced into Acinetobacter sp. strain HO1-N and Acinetobacter calcoaceticus BD413 by transformation and conjugal mobilization. The transformation frequencies of BD413 were 4.2 X 10(6) to 6.3 X 10(6) transformants per micrograms of DNA per 10(9) recipient cells. Conjugal mobilization frequencies were 1.1 X 10(-1) to 8.5 X 10(-1) per recipient. An improved method for the transformation of A. calcoaceticus BD413 is reported.

摘要

通过转化和接合转移,将R300B -、RSF1010 -和RK2衍生的质粒导入不动杆菌属菌株HO1 - N和醋酸钙不动杆菌BD413。BD413的转化频率为每微克DNA每10⁹个受体细胞产生4.2×10⁶至6.3×10⁶个转化子。接合转移频率为每个受体1.1×10⁻¹至8.5×10⁻¹。报道了一种改进的醋酸钙不动杆菌BD413转化方法。
