Bacteria that can utilize glyphosate (GP) or methylphosphonic acid (MPA) as a sole phosphorus source have been isolated from soil samples polluted with organophosphonates (OP). No matter which of these compounds was predominant in the native habitat of the strains, all of them utilized methylphosphonate. Some of the strains isolated from GP-polluted soil could utilize both phosphorus sources. Strains growing on glyphosate only were not isolated. The isolates retained high destructive activity after long-term storage of cells in lyophilized state, freezing to -20 degrees C, and maintenance on various media under mineral oil. When phosphorus-starved cells (with 2% phosphorus) were used as inoculum, the efficiency of OP biodegradation significantly increased (1.5-fold).
已从受有机膦酸盐（OP）污染的土壤样本中分离出能够将草甘膦（GP）或甲基膦酸（MPA）作为唯一磷源利用的细菌。无论这些化合物中哪一种在菌株的原生栖息地占主导地位，它们都能利用甲基膦酸盐。从受GP污染的土壤中分离出的一些菌株可以利用这两种磷源。未分离到仅在草甘膦上生长的菌株。这些分离株在细胞冻干状态下长期保存、冷冻至-20摄氏度以及在矿物油下的各种培养基上保存后，仍保留着较高的破坏活性。当使用缺磷细胞（含2%磷）作为接种物时，OP生物降解效率显著提高（1.5倍）。
