| 中文摘要 | in this study, the possibility of establishing a dual-species biofilm from a bacterium with a high biofilm-forming capability and a 3,5-dinitrobenzoic acid (3,5-dnba)-degrading bacterium, comamonas testosteroni a3, was investigated. our results showed that the combinations of strain a3 with each of five strains with a high biofilm-forming capability (pseudomonas sp. m8, pseudomonas putida m9, bacillus cereus m19, pseudomonas plecoglossicida m21 and aeromonas hydrophila m22) presented different levels of enhancement regarding biofilm-forming capability. among these culture combinations, the 24-h dual-species biofilms established by c. testosteroni a3 with p. putida m9 and a. hydrophila m22 showed the strongest resistance to 3,5-dnba shock loading, as demonstrated by six successive replacements with dmm2 synthetic wastewater. the degradation rates of 3,5-dnba by these two culture combinations reached 63.3-91.6% and 70.7-89.4%, respectively, within 6 h of every replacement. using the gfp-tagged strain m22 and confocal laser scanning microscopy, the immobilization of a3 cells in the dual-species biofilm was confirmed. we thus demonstrated that, during wastewater treatment processes, it is possible to immobilize degrader bacteria with bacteria with a high biofilm-forming capability and to enable them to develop into the mixed microbial flora. this may be a simple and economical method that represents a novel strategy for effective bioaugmentation. |
