Strains
SA33T and 7A078 could grow in the presence of 5 mM
AlCl3 in 0.1% BactoTryptone (Difco) adjusted to pH 3.5
with sulfuric acid, whereas the closely related type strains
except those of B. tropica and B. unamae did not. Standard
physiological tests were carried out according to the
methods described previously (Smibert & Krieg, 1994).
