Transformation of Streptococcus lactis Protoplasts by Plasmid DNA †

AUTOR(ES)
RESUMO

Polyethylene glycol-treated protoplasts prepared from Streptococcus lactis LM3302, a lactose-negative (Lac−) derivative of S. lactis ML3, were transformed to lactose-fermenting ability by a transductionally shortened plasmid (pLM2103) coding for lactose utilization.
