1-aminocyclopropane-1-carboxylate + H2O	Pseudomonas brassicacearum	ACC deaminase activity is an important trait of plant growth-promoting rhizobacteria, PGPR, that stimulates root growth in infected plants, e.g. in soil-grown tomato Lycopersicon esculentum cv. Ailsa Craig. All the Pseudomonas brassicacearum strains studied cause pith necrosis when stems or fruits are inoculated with a bacterial suspension, as does the causal organism of this disease Pseudomonas corrugata strain 176, but the non-pathogenic strain Pseudomonas sp.
