| 1. | Study on pd , ag and co catalysts supported on zro2 for complete methane oxidation
催化剂用于甲烷完全氧化反应的研究 |
| 2. | The results showed that methane oxidation ability was different in various soil and possibly it was related to the basic properties of the soil . microorganisms were responsible to methane oxidation
2 )对设施蔬菜栽培土壤甲烷氧化的研究结果表明，不同土壤对甲烷的氧化能力各异，这可能与土壤的理化性质有关。 |
| 3. | The related current research status is introduced and a preliminary conclusion was drawn on the mechanism of methane oxidation by methanotroph , its physiolony and distribution in ecosystems , as well as potential use of methanotroph in biodegradation of gas
介绍了瓦斯微生物治理技术的国内外研究现状、甲烷氧化菌氧化甲烷的机理和影响因素，以及甲烷氧化菌的生态分布。 |
| 4. | The utilization of c sources by a methanotrophic isolate from the soil was also detected . it was supposed that the facultative methanotrophs might be dominant for methane oxidation as methane released weakly in the greenhouse soil
此外，还研究了从土壤中分离的甲烷氧化菌对碳源的利用情况，表明在甲烷释放极少的设施栽培土壤中，兼性营养的甲烷氧化菌可能在甲烷氧化中占据主导地位。 |
| 5. | Glucose could obviously increase the flux of n2o among the carbon sources detected . that the methane - oxidizing bacteria probably were also one of microbiological populations producing n2o was proposed , based on research work . 2 ) methane oxidation ability of green - house soil was detected
研究也表明在自然界中除了硝化(包括自养和异养型)细菌和反硝化细菌种群以外，甲烷氧化菌可能也是对氧化亚氮释放具有一定贡献的细菌类群。 |
| 6. | This paper deals with the fluxes of nitrous oxide from green - house soil , the methane oxidation by the soil , and microbiological mechanisms . the results obtained were reported as the followings : 1 ) it showed that the flux of n2o from the greenhouse was much higher than that from the bare land
因此，研究农业设施栽培条件下，甲烷和氧化亚氮排放及其微生物学机理，既可明确甲烷和氧化亚氮的排放通量，又能提供有效控制甲烷和氧化亚氮排放的措施，为农业和环境的可持续发展提供科学依据。 |
| 7. | N sources ( including organic and inorganic n tested ) and c sources tested could restrain methane oxidation . cellulose inhibited methane oxidation most weakly while the high concentration of methanol and glucose did dramatically , but the proper concentration of methanol could stimulate soil methane oxidation sharply . in the middle process of methane oxidation , addition of glucose could restrain methane oxidation shortly but the inhibition could be relieved about 5 days later when supplied again with enough oxygen
土壤微生物是甲烷氧化的主要生物类群，含水量对土壤甲烷氧化活性有明显影响，过高或过低对甲烷氧化均具有抑制作用；氮源(包括有机和无机氮源)对甲烷氧化均有抑制作用；不同碳源对甲烷氧化的影响各异，纤维素对甲烷氧化抑制作用最小，而高浓度的甲醇、葡萄糖则对甲烷氧化具有强烈抑制作用；而适当浓度的甲醇可极大促进土壤对甲烷的氧化：在甲烷氧化过程中加入葡萄糖能迅速抑制甲烷氧化；在加入葡萄糖的同时保持瓶中充足的氧气，则这种抑制作用可以在重新培养一定时间后得到解除。 |
