A strain of Burkholderia cepacia isolated by enrichment culture utilized L-2-amino-3-phosphonopropionic acid (phosphonoalanine) at concentrations up to 20 mM as a carbon, nitrogen, and phosphorus source in a phosphate-insensitive manner. Cells contained phosphoenolpyruvate phosphomutase activity, presumed to be responsible for cleavage of the C---P bond of phosphonopyruvate, the transamination product of L-phosphonoalanine; this was inducible in the presence of phosphonoalanine.
通过富集培养分离得到的一株洋葱伯克霍尔德菌，能够以对磷酸盐不敏感的方式，利用浓度高达20 mM的L-2-氨基-3-膦酰丙酸（膦酰丙氨酸）作为碳源、氮源和磷源。细胞含有磷酸烯醇式丙酮酸磷酸变位酶活性，推测该酶负责催化膦酰丙酮酸（L-膦酰丙氨酸的转氨产物）中C---P键的断裂；在膦酰丙氨酸存在的情况下，该酶可被诱导产生。
