Abstract

SUMMARY: Data from two experiments indicated that transformation occurred in in the conversion of lactose-negative to lactose-positive cells. When the DNA from prototrophic cells was mixed in media with auxotrophic cells approximately 0.1% of the recipient cells were transformed to prototrophs.

Transformation activity of the donor DNA was found to diminish with heat, DNase or 2-deoxyglucose. The frequencies of transformation obtained in this study compare with those observed in other fungi and some bacteria.
