Pseudomonas syringae cultured in a defined citrate medium supplemented with 1 mM aluminium, chromium and manganese, respectively, appeared to elicit disparate biochemical responses. At the stationary phase of growth aluminium was predominantly present as an insoluble residue. Although virtually none of this metallic element was detected in the supernatant, the bacterial cells appeared to contain some aluminium. Following the initial uptake of chromium the microbe secreted the metal in the supernatant. Only a small fraction of the chromium was localised in the bacterial cells; 91% manganese was biotransformed into an insoluble pellet. No citrate was detected in the exocellular fluid at cessation of cellular growth.
分别在添加了1 mM铝、铬和锰的特定柠檬酸盐培养基中培养的丁香假单胞菌似乎引发了不同的生化反应。在生长稳定期，铝主要以不溶性残渣的形式存在。尽管在上清液中几乎检测不到这种金属元素，但细菌细胞似乎含有一些铝。在最初摄取铬之后，微生物将这种金属分泌到上清液中。只有一小部分铬存在于细菌细胞中；91%的锰被生物转化为不溶性沉淀。细胞生长停止时，细胞外液中未检测到柠檬酸盐。
