- Experiments showed that the strengh of soil can be enhanced by either applying slime-forming bacteria directly to the soil matrix to produce a biopolymer inside it, or by applying biopolymer from slime-forming bacteria or commercial products such as poly-3-hydroxybutyrate (PHB), xanthan gum, and sodium alginates to the soil matrix. The cross-linked support networks result from the interaction of biopolymer with the soil matrix.
Zonal bioremediation or enbironmental encapsulation is potential applications of this research. Reduction of soil erosion and enhancement of the soil strength in the foundations of hydraulic systems may also be good prospects for geotechnical and agricultural exploration.
