| 摘 要： | 堆肥系统内氧浓度一直是影响堆肥进程的重要因子,它决定了堆肥系统中微生物活动的强弱,从而影响堆肥中复杂有机物的分解速率.该文研究了氧浓度对纤维素降解复合菌系MC1功能的影响.通过不同封口方式与不同大小容器培养实验,揭示静置培养条件下复合菌系MC1在纤维素降解过程中,氧浓度对该复合菌系分解纤维素能力的影响.得出复合菌系MC1在微耗氧条件下(＜0.05 mg/L)分解纤维素,分解纤维素最佳的氧浓度范围在0.01～0.02 mg/L,氧浓度过高或过低均不利于纤维素的分解.特定氧浓度有利于复合菌系MC1执行分解功能. |
| 关 键 词： | 氧浓度 复合菌系MC1 纤维素降解 |

| Abstract: | The oxygen concentration in compost system is a very important factor which influences composting process. It determines the activity of micro-organism in the compost system and then influences the degradation rate of complex organic materials in the compost. The influence of oxygen concentration on cellulose decomposing function of a composite microbial system MC1 was investigated. In order to find out the oxygen dependence and influence of environment oxygen concentration on this composite microbial system under static submerged culture conditions, two groups of experiments were designed to research this influence during cellulose decomposition process. One group used different sealed ways, and the other group used different cylindrical containers (different depths and diameters). The results show that oxygen is an indispensable factor in cellulose decomposition process, and the optimum concentration of environment oxygen was within 0.01-0.02 mg/L during cellulose decomposition process. The special oxygen concentration has an important influence on cellulose decomposing function of this microbial system. |
| Keywords: | oxygen concentration composite microbial system MC1 cellulose decomposition |
