Transfer of plasmid DNA to Brevibacterium lactofermentum by electrotransformation.


The Escherichia coli-Brevibacterium lactofermentum shuttle vector pBLA was introduced into intact cells of B. lactofermentum by electrotransformation. Several parameters of this procedure such as voltage and cell concentration were analysed. Optimal conditions gave an efficiency of 10(6) transformants per microgram of DNA. Two recalcitrant strains could be… (More)
