Abstract

SUMMARY: Protoplasts of Sarcina lutea and Streptococcus faecalis underwent thermal lysis when heated to 60° and above. [14C]Glycine was released from the internal pool of Strep, faecalis at 50°. Spermine, spermidine, cadaverine and Mg2+ partially protected protoplasts against thermal lysis.
