[Comparative study of transformation and fusion induced by polyethylene glycol in Acholeplasma laidlawii B].

This study showed in Acholeplasma laidlawii the possibility of transformation and fusion of protoplasts after induction by polyethylene glycol. Recombination in a genome of the resistance to chloramphenicol and neomycin has been obtained. Minimal inhibitory concentration of these antibiotics towards the recombined strain are identical to those measured with the parental strains.
