Ice nucleation activity of some reference cultures of Pseudomonas syringae and field isolates of bacteria from wheat and barley in Queensland
1986
Newton, D. | Hayward, A.C. (Queensland Univ., St Lucia (Australia). Dept. of Microbiology)
When Australian reference cultures of Pseudomonas spp. and pathovars of P. syringae were examined for ice nucleation activity, 14 out of 60 were positive (3 out of 4 isolates of P. syringae pv. pisi and 11 out of 17 isolates of P. syringae pv. syringae). When bacterial isolates from wheat, barley and other grasses were tested, 18 out of 174 were positive of which 5 were P. syringae and 13 were identified using the API 2OE system as a relatively uniform biotype of Erwinia herbicola. All but two of the E. herbicola isolates and all of the P. syringae isolates were isolated from wheat and barley at a single site near Toowoomba.
