Optimization of Electroporation Conditions for Bacillus pumilus 3–19 Strain

Description
Summary:Electroporation is the process of using electrical impulses to create temporary pores in the plasma membrane which, in turn, enables the penetration of nucleic acids into the cytoplasm of a cell. This method is widely used for the rapid and efficient introduction of foreign DNA into a wide range of cells. Cell viability and electrotransfection efficiency depend on various experimental factors, including the impulse form, vector concentration, cell type (density), properties of the electroporation buffer, and the growth phase of the bacterial culture. In this work, we investigated the optimal conditions for the transformation of the Bacillus pumilus 3–19 strain using electroporation. Competent B. pumilus cells were obtained on the 4th hour of culture growth using PEB1 electroporation buffer and SOC1 (Super Optimal broth with Catabolic repressor) medium, while the electric field strength was 12 kV/cm. With these parameters, the transformation efficiency of bacillus cells was 56.3 transformants/μg DNA. Thus, the rational choice of pulsation conditions and buffering compositions is critical for the design of electroporation protocols to maximize the viability and efficiency of electrotransfection.
