“…Twenty grams of 0.5 mm diameter soil samples were air-dried, then put into a glass incubator, and added with 40 ml of distilled water, mixed gently, and then put into the incubator at 30°C. The gas production protocol was adopted from Susilowati (2007) with the modification of adding acetylene as an inhibitor of methane oxidation (Watanabe et al 1995(Watanabe et al , 1997Chan & Parkin 2000). Fifty ml of acetylene was added into each 1000 ml of air in the headspace room of the glass incubator (Watanabe et al 1995).…”

“…After getting the concentration at times C 0 and C 24 , the gas production (in µg CH 4 /kg soil/day) was calculated using the following formula: The measurement of CH 4 -OP used the same procedure as the measurement of CH 4 -PP above, excluding the addition of acetylene into the samples (Watanabe et al 1995(Watanabe et al , 1997Chan & Parkin 2000). The difference between CH 4 production with and without the inhibitor is the amount of CH 4 oxidized (CH 4 -OP).…”

Mujiyo M., Sunarminto B.H., Hanudin E., Widada J., Syamsiyah J. (2017): Methane production potential of soil profile in organic paddy field. Soil & Water Res., 12: 212−219.The use of organic fertilizers in the organic paddy/rice field can increase methane (CH 4 ) production, which leads to environmental problems. In this study, we aimed to determine the CH 4 production potential (CH 4 -PP) by a soil profile from samples using flood incubation. Soil properties (chemical, physical, and biological) were analyzed from soil samples of three different paddy farming systems (organic, semi-organic, and conventional), whilst soil from teak forest was used as the control. A significant relationship was determined between soil properties and CH 4 -PP. The average amount of CH 4 -PP in the organic rice field profile was the highest among all the samples (1.36 µg CH 4 /kg soil/day). However, the CH 4 oxidation potential (CH 4 -OP) is high as well, as this was a chance of mitigation options should focus on increasing the methanotrophic activity which might reduce CH 4 emissions to the atmosphere. The factor most influencing CH 4 -PP is soil C-organic (C org ). C org and CH 4 -PP of the top soil of organic rice fields were 2.09% and 1.81 µg CH 4 /kg soil/day, respectively. As a consequence, here the mitigation options require more efforts than in the other farming systems. Soil with various amounts of C org reached a maximum point of CH 4 -PP at various time after incubation (20, 15, and 10 days for the highest, medium, and the lowest amounts of C org , respectively). A high amount of C org provided enough C substrate for producing a higher amount of CH 4 and reaching its longer peak production than the low amount of C org . These findings also provide guidance that mitigation option reduces CH 4 emissions from organic rice fields and leads to drainage every10-20 days before reaching the maximum CH 4 -PP.

“…A variety of chemicals used in agriculture such as pesticides and herbicides and nitrification inhibitors, are known to affect microbial processes. It is well established that CH 4 production is inhibited by acetylene, aminopurine, ammoniumthiosulphate, carbofurane, calcium carbide (capsulated), DDT, dicyandiamide, methyle chloride, methyle fluoride, nitrapyrine, pyridine, organochlorine and sodium azide and CH 4 -acetylene, bromoxynil, dicyandiamide, DDT, 2,4,-D, ethylene, hexachlorocyclohexane, hydrazine, methomyle, nitrapyrine, phenylalanine, sodium thiosulphate, threonine and thiourea [9,25,147]. Nitrification inhibitors such as acetylene and nitrapyrin can inhibit the growth of nitrifiers, methanogens and methanotrophs [107].…”

Abstract. Methane has profound impact on the physico-chemical properties in atmosphere leading to global climate change. Out of the various sources of CH 4 , rice fields are the most significant contributors. The processes involved in the emission of CH 4 from rice fields to the atmosphere include CH 4 production (methanogenesis) in the soil by methanogens, methane oxidation (methanotrophy) by methanotrophs and vertical transfer of CH 4 via plant transport and diffusion or ebullition. In the overall methane dynamics rice plants act as : a) source of methanogenic substrate, b) conduit for CH 4 through well developed system of inter cellular air space (aerenchyma), and c) potential methane oxidizing micro-habitat in the rhizosphere by diffusing oxygen which favour the growth and multiplication of methanotrophs. Apart from mechanistic uncertainties, there are several other uncertainties in the estimation of CH 4 flux. Methane dynamics in the paddy field is controlled by a complex set of parameters linking the biological and physical characteristics of soil environment like temperature, carbon source, Eh, pH, soil microbes and properties of rice plants, etc. It has now become possible to isolate, detect and characterize the methanogens and methanotrophs by using molecular biological tools like PCR, FISH, etc. techniques. The apparent half saturation constant (K m ) and maximum oxidation rate (V max ) are distinctive parameters which determine the ability of bacteria to survive on atmospheric methane.

“…Biological methane oxidation to CO 2 can strongly reduce (B21-fold) climate forcing. Environmental parameters such as oxygenation and methane concentration, moisture content, pH, nitrogen sources and temperature can strongly influence this biological process in soil (Jones and Nedwell, 1993;Boeckx et al, 1996;Chan and Parkin, 2000;Borjesson et al, 2004;Scheutz and Kjeldsen, 2004). Another factor that might influence methane oxidation in soil is the presence of earthworms.…”

Effect of earthworms on the community structure of active methanotrophic bacteria in a landfill cover soil

In the United Kingdom, landfills are the primary anthropogenic source of methane emissions. Methanotrophic bacteria present in landfill biocovers can significantly reduce methane emissions via their capacity to oxidize up to 100% of the methane produced. Several biotic and abiotic parameters regulate methane oxidation in soil, such as oxygen, moisture, methane concentration and temperature. Earthworm-mediated bioturbation has been linked to an increase in methanotrophy in a landfill biocover soil (AC Singer et al., unpublished), but the mechanism of this trophic interaction remains unclear. The aims of this study were to determine the composition of the active methanotroph community and to investigate the interactions between earthworms and bacteria in this landfill biocover soil where the methane oxidation activity was significantly increased by the earthworms. Soil microcosms were incubated with 13 C-CH 4 and with or without earthworms. DNA and RNA were extracted to characterize the soil bacterial communities, with a particular emphasis on methanotroph populations, using phylogenetic (16S ribosomal RNA) and functional methane monooxygenase (pmoA and mmoX) gene probes, coupled with denaturing gradient-gel electrophoresis, clone libraries and pmoA microarray analyses. Stable isotope probing (SIP) using 13 C-CH 4 substrate allowed us to link microbial function with identity of bacteria via selective recovery of 'heavy' 13 C-labelled DNA or RNA and to assess the effect of earthworms on the active methanotroph populations. Both types I and II methanotrophs actively oxidized methane in the landfill soil studied. Results suggested that the earthworm-mediated increase in methane oxidation rate in the landfill soil was more likely to be due to the stimulation of bacterial growth or activity than to substantial shifts in the methanotroph community structure. A Bacteroidetes-related bacterium was identified only in the active bacterial community of earthworm-incubated soil but its capacity to actually oxidize methane has to be proven.
