,一种完全不含氮的坚韧的植物细胞壁成分。
Insects like termites can go whole hog on the whole log, because they can " chew" the wood with their serrated mandibles AND also have the right gut machinery - AKA microbes - to break the lignin down on the molecular level.
像白蚁这样的昆虫可以吃掉整根原,因为它们可以用锯齿状的下颚“咀嚼”
材,并且还有合适的肠道机制——也就是微生物——在分子水平上分解
。
