“…This study found that the composition of bacterial communities were dynamic in time for the communities in bulk soil and rice straw residues under both conditions and for both soil types. Other studies have also shown that the dynamic of bacterial communities colonizing rice straw residues ranges in different times both in flooded and dry conditions [12,19,[42][43][44]. Weber et al [19] showed that the bacterial community observed changes during the initial 15-day incubation period, but stability was observed during the remaining 71 days of incubation.…”

This study investigated the effect of upland crop rotation on soil bacterial community in bulk soil and rice straw residues in the alluvial soils. Soil samples and rice straw residues in two crop rotation models including triple rice and rice-upland crops were collected for incubation under anaerobic and aerobic conditions. Data were analyzed from Denaturing Gradient Gel Electrophoresis band patterns. The results showed that the composition and diversity of communities colonizing the rice straw residues differed from those inhabiting the bulk soil. The bacterial community composition and diversity were only moderately affected by rice straw residues in the bulk soil. Especially, this study indicated that the composition of the bacterial community associated with the bulk soil and rice straw residues was dynamic in two incubation conditions (aerobic or anaerobic) and the different crop rotation models. The findings of this study demonstrated that the bacterial diversity was not affected by the difference in continuous paddy rice cultivation compared to the upland crop rotation system.

A sediment microbial fuel cell (SMFC) is a system in which MFC is applied to a sediment layer of an aqueous system for water purification. SMFCs can remove contaminants from sediments and decompose organic matter while simultaneously producing electrical energy. SMFC is installed in the form of installing an anode in the sediment at the bottom of the water system and a cathode in the water layer above the sediment, and connecting the two electrodes through an external circuit. Early SMFCs were developed to be used as power sources in hard-to-reach deep water areas or remote areas. However, recently, it has attracted a lot of attention as a technology for biologically purifying pollutants through its own power supply. Furthermore, it is being developed as a means of monitoring the environmental condition of the installed area. Despite the importance of SMFC, no comprehensive review has yet been published to the Korean readers on the trends and prospects of SMFC research. Therefore, in this review paper, the mechanism of SMFC, their mechanism of removal of organic, inorganic, and heavy metals, and the current state of SMFC technology are discussed, and future prospects are presented.
