Abstract
Ochrolechia parella is one of the most abundant lichens colonizing granite monuments in the region of Galicia (N.W. Spain). Its interaction with granite used in the construction of four ancient monuments was studied using FT Raman spectroscopy to evaluate the production of calcium oxalate by this lichen and the relationship of this production with different environmental conditions, particularly humidity. The results obtained showed that Ochrolechia parella is an aggressive colonizer, causing chemical disturbances to the granite through the formation of both calcium oxalate monohydrate and dihydrate. Apothecial development appears to be related to the production of calcium oxalate, and humidity determines the state of hydration of the calcium oxalate in the thallus. © 1999 John Wiley & Sons, Inc.

花岗岩遗迹中斑蛭(ololechia parella (L.) mass的生物降解:FT拉曼光谱研究
在加利西亚(西班牙西北部)地区的花岗岩纪念碑中，红毛衣是最丰富的地衣之一。利用FT拉曼光谱研究了它与花岗岩的相互作用，以评估这种地衣产生草酸钙，以及这种生产与不同环境条件，特别是湿度的关系。结果表明，草酸钙是一种具有侵略性的定殖菌，通过草酸钙一水和草酸钙二水的形成对花岗岩造成化学干扰。茎尖的发育似乎与草酸钙的产生有关，而湿度决定了草酸钙在菌体中的水化状态。©1999 John Wiley &儿子,Inc。生物光谱学学报，2009,31 (2):559 - 559
