high frequency transformation of bacillus subtilis protoplasts by plasmid dna

For transformation to take place the recipient bacterium must be in a state of competence which might occur in nature as a time limited response to environmental conditions.

Bacillus subtilis is a gram positive species with several adaptive mechanisms for competition and environmental stress.

High frequency transformation of bacillus subtilis protoplasts by plasmid dna. These changes emerge from complex regulated pathways for adapting to external stresses including competition. A great deal is known therefore about this process for a review see dubnau 1982 because the transformation of competent cells by plasmid dna continues to be the most widely used means of introducing recombinant dna we shall discuss this process in some detail later.
