Abstract

Abstract: The brackish-water-adaptive electrochemical bacterial consortia in the sediment bioelectrochemical system (SBES) installed in a model tank simulating an aquaculture pond operated with brackish water were successfully enriched after 15 days. Total bacteria counts in the inoculum, the sediment of the SBES anode and the sediment of the control tank varied from 3.9 x 105 to 2.71 x 106 cfu g-1. Halophilic bacteria such as Vibrio sp., Pseudomonas sp. were found dominant in the anode of the SBES and might play a key role in the electron transfer process as well as in the performance under the saline conditions of the corresponding SBES. The composition and the diversity of the anode bacterial community enriched in the SBES were significantly different from that of the control not having electrodes but only slightly different from that of the inoculum.

Keywords: Brackish-water-adaptive electrochemical bacteria, sediment bioelectrochemical systems (SBESs), brackish aquaculture.
