In this study, bacteria consortium-encapsulated alginate/gellan gum microbeads (BAGMs) were successfully prepared and applied to enhance the biodegradation of total petroleum hydrocarbon (TPH) in the aquifer of groundwater. To find the optimal condition of preparing the microbeads for suitable migration in the aquifer, we experimented with varying the concentrations of gellan gum (0–2 g/L) and calcium ions (2.52–3.01 mM) with the emulsification-internal gelation. After that, soil column test was conducted to evaluate the improvement of biodegradation of TPH in groundwater contaminated with TPH. As a result, the TPH removal rate of BAGMs was higher than that of non-encapsulated bacteria and natural conditions. |
