Development of an improved cloning vector and transformation system in Amycolatopsis mediterranei (Nocardia mediterranei).
A versatile plasmid cloning vector pRL60 carrying kanamycin/neomycin resistance (km/neo), erythromycin resistance (ermE) and alpha-amylase (alpha-amy) marker genes that replicates in various Amycolatopsis mediterranei strains and Escherichia coli has been constructed. This cloning vector has been derived from a hybrid plasmid pRL50, which was developed by cloning ermE from pIJ4026 into a pRL1 d...
متن کاملTransformation of Bacillus polymyxa with plasmid DNA.
A plasmid transformation system was developed for Bacillus polymyxa ATCC 12321 and derivatives of this strain. The method utilizes a penicillin-treated-cell technique to facilitate uptake of the plasmid DNA. Low-frequency transformation (10(-6) per recipient cell) of plasmids pC194, pBD64, and pBC16 was accomplished with this method. Selection for the transformants was accomplished on both hype...
متن کاملTransformation of Azotobacter vinelandii with plasmid DNA.
Azotobacter vinelandii cells can be transformed at high frequencies with the broad-host-range plasmids pRK2501, RSF1010, and pGSS15, using a modification of the procedure developed by Page and von Tigerstrom (J. Bacteriol. 139:1058-1061, 1979) for chromosomal DNA-mediated transformation. The frequency of transformation per microgram of plasmid DNA per viable cell with pRK2501 and pGSS15 was abo...
متن کاملEfficient transformation of Amycolatopsis orientalis (Nocardia orientalis) protoplasts by Streptomyces plasmids.
Conditions for efficient transformation of Amycolatopsis orientalis (Nocardia orientalis) protoplasts by Streptomyces plasmid cloning vectors were identified. Three streptomycete plasmid origins of replication function in A. orientalis, as do the apramycin resistance gene from Escherichia coli, the thiostrepton resistance gene from Streptomyces azureus, and the tyrosinase gene from Streptomyces...
متن کاملTransformation of vegetative cells of Bacillus anthracis with plasmid DNA.
Methods have been developed for chemical transformation and electro-transformation (electroporation) of vegetative cells of Bacillus anthracis with supercoiled plasmid DNA. Chemical transformation was dependent on incubation in Tris/HCl with osmotic support and transformation with plasmid DNA was effected by treatment with polyethylene glycol 3350. Maximum transformation frequencies were 3.8 x ...
