摘要:
白蚁-细菌-真菌共生系统对自然界生物质降解具有重要作用,研究蚁巢伞(Termitomyces)对木质纤维素的降解能力有助于揭示其共生关系,为蚁巢伞应用于生物质能源开发提供理论依据。利用黑翅土白蚁(Odontotermes formosanus)菌圃(OFC),及其固体培养蚁巢伞(TA)、液体培养蚁巢伞(TL)分别对未经预处理和经密褐褶孔菌(Gloeophyllum trabeum)预处理材料进行降解试验,探究蚁巢伞的木质纤维素降解能力。结果显示,未经预处理时,处理90天后,OFC对纤维素、半纤维素和木质素的降解率分别为15.22%、29.34%和6.01%;处理120天后,TA对纤维素、半纤维素和木质素的降解率分别为20.98%、31.89%和11.68%,TL对纤维素、半纤维素和木质素的降解率分别为14.39%、24.62%和5.05%。经过预处理时,处理120天后,OFC对纤维素、半纤维素和木质素的降解率分别为37.09%、42.20%和24.95%,TA对纤维素、半纤维素和木质素的降解率分别为34.77%、38.29%和29.74%,TL对纤维素、半纤维素和木质素的降解率分别为30.57%、30.47%和24.36%。三种状态蚁巢伞对经预处理材料木质纤维素降解率均高于未经预处理材料。研究表明,蚁巢伞对木质纤维素具有一定的降解能力,尤其是蚁巢伞对木质素的降解说明其可以打破木质素屏障,证实了利用蚁巢伞的木质纤维素降解能力来实现生物质能源化的潜力,间接为蚁巢伞的人工栽培提供参考。(图4 表2 参39)
Abstract:
The symbiotic system formed by termites-bacteria-fungus plays a very important role in the degradation of biomass in nature world . To study the ability of symbiotic Termitomyces to degrade lignocellulose will help to reveal the relationship between Termitomyces and termites. It also provides theoretical basis for using Termitomyces to develop biomass energy. The wood materials both without pretreated and pretreated by Gloeophyllum trabeum were treated by Odontotermes formosanus fungus comb s ( OFC), solid culture of Termitomyces ( TA) and liquid culture of Termitomyces ( TL), respectively, for which to investigate the ability of Termitomyces to degrade lignocellulose. In the non-pretreated wood materials degradation test, when treated for 90 days, the degradation rate of cellulose, hemicellulose and lignin by OFC were 15.22%, 29.34%, and 6.01%, respectively. And when treated for 120 days, the degradation rate of cellulose, hemicellulose and lignin by TA were 20.98%, 31.89%, and 11.68%, respectively. The degrad ation rate of cellulose, hemicellulose and lignin by TL were 14.39%, 24.62%, and 5.05%, respectively. In the pretreat ed wood materials degradation test, after 120 days of treatment, the degradation rate of cellulose, hemicellulose and lignin by OFC were 37.09%, 42.20% and 24.95%, respectively. The degradation rate of cellulose , hemicellulose and lignin by TA were 34.77%, 38.29% and 29.74%, res pectively. The degradation rate of cellulose, hemicellulose and lignin by TL were 30.57%, 30.47 % and 24.36%, respectively. In addition, the lignocellulose degradati on rate of pretreated wood materials by OFC, TA and TL was higher than that of the non-pretreated wood materials. Termitomyces has a certain degradation effect on lignocellulose. Especially, the lignin biodegradation ability of Termitomyces shows it can break th e lignocellulosic lignin barrier . This confirms the potential of using Termitomyces to degrade lignocellulose to achieve the energy utilization of woody biomass, and also provides references for artificial cultivation of Termitomyces indirectly. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
