Biodegradation of woody substance by aerobic soil bacteria and difference in the durability of sawdusts against soil bacteria have been studied.The results are summerized as follows:1. Woody substance has not easily been degraded by aerobic soil bacteria when they are attacked by aerobic soil bacteria in the presence of non-woody substances such as garbage (food related organic substances).2. Although the contents of the hot water extracts have increased and the contents of the hollocelluloses have decreased, the contents of the lignin have not changed drastically during the oeration of a GADEmachine for three monthes.3. Vacant space, water retention, and water drainage of sawdusts have changed according to the size of the particles of the sawdusts.4. Durability of the sawdusts against the abrasion in the GADE machine is different in the size of the particle of the sawdusts.5. Water soluble substances have effected on the growth of the bacteria in different concentarations.

研究了好氧土壤细菌对木质物质的生物降解及木屑对土壤细菌耐受性的差异。结果表明：1.在垃圾等非木质物质(与食物有关的有机物)存在的情况下，木质物质不易被好氧土壤细菌降解。虽然热水浸出物的含量有所增加，而综纤维素的含量有所下降，但木质素的含量在三个月的时间里没有明显的变化。锯末的空置空间、保水性和排水量随锯末颗粒大小的不同而不同。GADE磨机中锯末的耐磨性因锯末颗粒大小不同而不同。不同浓度的水溶性物质对细菌的生长有不同的影响。
