热带雨林环境霉菌试验菌种筛选研究

Filtration for Strain of Fungus Test in Tropical Rainforest

目的研究西双版纳热带雨林环境空气中的优势菌种和装备上的敏感菌种,为热带雨林环境霉菌试验的菌种筛选提供参考。方法采用撞击法采集西双版纳试验站空气中的菌种,同时挑取试验站内正在进行环境试验的装备上生长的霉菌,通过纯化、鉴定、分析得到西双版纳热带雨林环境优势菌种和装备上的敏感菌种。结果获得热带雨林环境优势菌种12株,装备材料上的敏感菌种10株。结论根据霉菌对纤维、塑料、皮革、橡胶和纺织品的影响,筛选出6株优势菌种结合10株敏感菌种作为装备霉菌试验添加菌种。

Objective To research predominance strain of tropical rainforest in Xishuangbanna and sensitive strain of equip-ment to provide a reference for filtration for strain of fungus test in tropical rainforest. Methods The impact method was used to collect the strain from the air of Xishuangbanna. The strain on the surface of equipment in tropical rainforest in the station was picked for purification, identification and analysis. The dominant bacteria in tropical rainforest in Xishuangbanna and the sensi-tive strain on equipment were obtained. Results Twelve dominant strains of tropical rainforest and ten sensitive strains on equipment material were obtained. Conclusion Based on influences of mould on fiber, plastics, leather, rubber and textile, six dominant strains and the ten sensitive strains are selected to join the fungus test of equipment.
