Accumulation and Phytotoxicity of Two Commercial Biocides in the Lichen Evernia prunastri and the Moss Brachythecium sp.

This study investigated the accumulation and phytotoxicity of two commercial biocides widely used for removal biological colonization from monuments, namely Biotin T® (3%) Preventol RI80® (2%), on lichen moss model species, specifically, Evernia prunastri Brachythecium sp. The active compounds, benzalkonium chloride (BAC) RI80 isothiazolinone (OIT) T, were accumulated in similar amounts both species without significant changes up to 21 days. Both compounds caused a severe impairment photosynthetic apparatus these any recovery over time, although T showed faster stronger action, was more sensitive than lichen. By shedding light BAC OIT lichens mosses quantifying their effectiveness photosynthetically devitalize organisms, obtained results are useful comparison implementation green alternative products control biodeteriogens.
