测试了来自草甘膦或烷基膦酸盐污染土壤的四种细菌菌株利用不同有机膦酸盐的能力。所有研究的菌株都很容易利用甲基膦酸和许多其他膦酸盐，但其降解草甘膦的能力不同。仅菌株 Ochrobactrum anthropi GPK 3 和 Achromobacter sp。 Kg 16 在从含有草甘膦的富集培养物中分离后使用了该化合物。无色杆菌属MPK 7 来自相同的富集培养物，类似于无色杆菌属。 MPS 12 来自甲基膦酸盐污染源，需要适应 GP 上的生长。研究的菌株在生长参数、膦酸盐降解效率和该过程的特征产物以及能量代谢方面存在显着差异。这些差异为提出膦酸盐污染土壤中微生物群落中这些菌株之间相互作用的可能模型提供了基础。
Four bacterial strains from glyphosate- or alkylphosphonates-contaminated soils were tested for ability to utilize different organophosphonates. All studied strains readily utilized methylphosphonic acid and a number of other phosphonates, but differed in their ability to degrade glyphosate. Only strains Ochrobactrum anthropi GPK 3 and Achromobacter sp. Kg 16 utilized this compound after isolation from enrichment cultures with glyphosate. Achromobacter sp. MPK 7 from the same enrichment culture, similar to Achromobacter sp. MPS 12 from methylphosphonate-polluted source, required adaptation to growth on GP. Studied strains varied significantly in their growth parameters, efficiency of phosphonates degradation and characteristic products of this process, as well as in their energy metabolism. These differences give grounds to propose a possible model of interaction between these strains in microbial consortium in phosphonate-contaminated soils.
