title: Action of lysozyme on penicillin-induced filaments of Proteus vulgaris.
abstract: Penicillin-induced filaments of Proteus vulgaris P 18 had a seemingly unaltered cell envelope. Lysozyme, however, reduced the wall part of these filaments into a three-layered structure and caused transformation into spheroplasts. Although cross walls and membrane septa were absent in the filaments, most of the lysozyme-induced spheroplasts remained attached to each other.
