摘要
对不同腐烂程度毛竹篼的成分及酶活进行分析，结果表明降解过程中各成分和酶活都呈现一定的规律和相关性。在降解过程中，灰分、热水抽出物、1％NaOH抽出物、综纤维素、纤维素、酸不溶木质素最高值分别为32．39％、14．03％、48．13％、58．53％、41．45％、50．67％；最低值分别为3．32％、5．44％、27．70％、27．54％、24．67％、25．15％。滤纸酶活、棉花酶活、CMC纤维素酶活最高值分别为116．79×10^3U／kg、155．90×10^3U／kg、76．66×10^3U／kg。漆酶酶活、锰过氧化物酶活、木质素过氧化物酶活最高值分别为18．15×10^3U／kg、9．60×10^3U／kg、0．32×10^3U／kg。前、后期酶活都较低：中期物质丰富的时候，微生物大量生长、繁殖，酶活较高。
The analysis of composition and enzyme activity of the bamboo stump on different decomposition degree, results showed that each ingredient and enzyme activity present certain regularity and correlation in the degradation process. During the process of degradation,ash,hot water extract, I%NaOH extract, cellulose,cellulose, acid-insoluble lignin high values was 32.39%, 14.03%, 48.13%, 41.45%, 50.67%; minimum values was 3.32%, 5.44%, 27.7%, 24.67%, 25.15%. Filter paper enzyme activity and CMC enzyme activity and cotton cellulose enzyme supreme values was 116.79 × 10^3 U/kg, 155.90 × 10^3 U/kg, 76.66 × 10^3 U/kg. Laccase, manganese peroxidase and lignin peroxidase enzyme activity maximum values was 18.15 × 10^3 U/kg, 9.60 × 10^3 U/kg, 0.32 × 10^3 U/kg. Earlier and later stage enzyme activity was low, when medium-term ingredient rich, microbial growth, reproduction, enzyme activity was high.
