Biodegradation of diesel by mixed bacteria immobilized onto a hybrid support of peat moss and additives: A batch experiment
We report microbial cell immobilization onto a hybrid support of peat moss for diesel biodegradation. Three strains isolated from a site contaminated with diesel oil were used in this study: Acinetobacter sp., Gordonia sp., and Rhodococcus sp. To increase not only diesel adsorption but also diesel biodegradation, additives such as zeolite, bentonite, chitosan, and alginate were tested. In this study, a peat moss, bentonite, and alginate (2/2.9/0.1 g, w/w/w) hybrid support (PBA) was the best support matrix, considering both diesel physical adsorption capacity and mixed microbial immobilization.
