曾候乙墓穴木椁微生物降解对木材危害及防治措施研究

Study on Danger and Control of Microorganism Degradation to Coffin Wood in Zeng Houyi Tomb

从曾候乙墓分离到的16株菌,其中有11株为芽孢杆菌属类,4株微杆菌属,1林为黄色杆菌属。将16株细菌分别侵染6种木材,结果证明细菌降解对6种木材均有不同的韧性下降,个别木材出现腐烂病灶。2号菌降解后对泡桐、枣树、马尾松、香樟、刺槐和桑树分别下降8％,12％,10％,5％,10％和13％。3,5,6,7,8,9和16号菌对上述6种木材也有不同程度影响。而4,11,12,13,14和15号菌对6种木材的韧性下降影响不明显。但其渗透性大大提高了,因此也会影响木材的使用年限。采用杀菌、杀虫的石油气,乙醇等有机溶济,防治微生物降解产物对木材的浸蚀,均有较好的防菌、防认腐效果。

The sixteen typical strains were obtained from coffin of Zeng houyi tomb. Eleven of them belong to genus Bacillus, four are genus Microbacterium and one Xanthobacter wiegeletal flauus. Six species wood: paulownia fortunei, ziay-phus jujubausr inermis, pinus massonian.innamoinum caphora, robinia pseudoacacia and moms alba, were infected with sixteen strains,respectively, which caused tenacity of six woods to decrease incoordinately, even rotted. So life span of the wood would be affected.
