[Properties of the bacteriocin of Erwinia aroideae]

Erwinicin, produced by Erwinia aroideae cells, consists of rod-shaped particles. The molecular weight of such particles, determined by the method of sedimentation in saccharose gradient, is 15 megadaltons. The size of the particles is 14 x 160 nm. The preparations of erwinicin are thermolabile, insensitive to the action of RNAase, pronase, DNAase and possess antigenic properties. The synthesis of erwinicin is an inducible process.
