The objective of this research is to employ polymer-producing bacteria under an in-situ environment to a soil of inferior strength so that the biopolymers released can serve as a binder in soil particles to enhance the soil strength. The goal is to provide a cost-effective, environmentally-acceptable, in-place method to increase the strength of the soil matrix. It could also be possible that this technology can be extended to minimize risks associated with land subsidence due to fossil energy exploitation.

本研究的目的是利用聚合物生产 细菌在原位环境下的劣化土壤 强度，使得释放的生物聚合物可以用作粘合剂， 土颗粒，以提高土壤强度。 目标是 提供一个具有成本效益的，环境可接受的， 增加土壤基质强度的方法。 它也可以 这项技术有可能被推广到最小化风险 与化石能源开采引起的地面沉降有关。
