Biodeterioração em construções por fungos

Abstract

Biodeterioration in building materials have been poorly reported in Brazil and it is an important topic considering the economic and social aspects. The installation of fungi on substrates could be influenced by humidity, temperature, geographic region, and a source of nutrients, this installation has been associated with increased risk of diseases including asthma, allergies among others. This paper was divided into two parts. In the first, we report the general aspects of the Fungus kingdom, addressing nutritional, physiological, taxonomic and reproductive characteristics. The second part is a survey based on several published articles on biodeterioration in some building materials, describing methodologies and reporting results. The findings include Penicillium, Aspergillus, Stachybotrys and Trichoderma as major colonizers among others, assessing the impact of humidity and temperature in its existence, pointing out some mycotoxins produced by some microorganisms antifungal and antimycotic most efficient at the moment.
