Spider silk is highly resistant to rotting.
Spider silk possesses remarkable properties that make it significantly resistant to decomposition. Unlike many other organic materials, spider silk does not readily rot when exposed to the elements and microbial life.
Resistance to Decomposition
Based on observations and studies, spider silks have been seldom observed to decompose in nature. This is noteworthy because spider webs and threads are constantly exposed to a wide variety of saprophytic microbial organisms—microbes that feed on decaying organic matter and are the primary cause of rotting.
Inhibiting Microbial Growth
Laboratory studies have further supported these field observations. These studies have shown that spider silk is not only inherently resistant to degradation but also appears to inhibit microbial growth. This dual action—resisting breakdown and deterring the microbes that cause it—contributes significantly to the silk's longevity in various environments.
This natural durability is one of the many fascinating aspects of spider silk, contributing to its strength and stability even when left exposed outdoors.
