METHOD AND SYSTEM FOR CONTROLLING MICROBIAL REACTIONS IN BENTHIC SOIL

WIPO Patent Application WO/2013/137122

A1

[Problem] To provide a method and a system whereby various microbial reactions in various kinds of soils can be appropriately controlled in accordance with a benthic soil. [Solution] A method for controlling microbial reactions in a benthic soil, said method comprising burying a first electrode (11) in an anaerobic soil (E) in a benthic region, setting up a second electrode (12) in water (W) thereabove, and controlling the first electrode (11) to a redox potential (V), at which a definite microbial reaction in the soil (E) is inhibited or promoted, by a potential controller (20) that is connected between the electrodes (11) and (12). For example, the first electrode (11) is controlled to a redox potential, at which a methane gas synthesis reaction of a methane-producing bacterium is inhibited, or to another redox potential at which a reduction reaction of a nitrous oxide-reducing microorganism is promoted. In a preferred embodiment, the yield of a product obtained by a definite microbial reaction is monitored while changing the potential of the first electrode (11) by the potential controller (20) to detect a redox potential (V) at which the definite microbial reaction in the soil (E) is inhibited or promoted, and then the first electrode (11) is controlled to the potential thus detected.
