Results showed that:there were significant differences in the carbon to oxygen ratioamong various positions and processingconditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface,whichindicated some structure of cellulose and hemicellulose,while the effects of processing with boracic acid were not apparent;the bamboo processed in hightemperature and with boracic acid showed decreasedfree hydroxide and activity at the same time;the amount of active free hydroxide of inner layer was higher thanthat of the outer.

结果表明：不同部位和不同处理条件下竹材表面的碳氧比有很大差异；竹材表面主要以木素和各种抽提物为主；高温干燥导致竹材表面易挥发的抽提物分解，使部分纤维素和半纤维素的结构特征得以显露，而硼酸处理效果不明显；高温处理和硼酸处理后竹材表面的自由羟基减少，活性降低；竹黄表面的活性自由羟基的数量高于竹青表面。

Clostridium botulinum bacteria is anaerobic, which means it can survive and grow with little or no oxygen.

肉毒梭菌为厌氧细菌，这意味着它可以生存和发展与很少或根本没有氧气。
