“…Paint degradation related to the presence of biofilm was shown to be very low, but progressed faster in Ubatuba [8]. Other researchers also isolated cyanobacteria from painted buildings in Latin America [9][10][11]. Stenotrophomonas maltophilia were also detected in water-based acrylic paints [12].…”

“…and Cladosporium sp. [9,11,14,15,[32][33][34][35][36] were also frequently found. In addition, Lugauskas et al (2003) identified fungi from the genera of Aureobasidium pullulans, Aspergillus niger, Aspergillus versicolor, Cladosporium cladosporioides, Paecilomyces sulphurellus, Trichoderma viride, Ulocladium atrum as capable of degrading polymer materials [37].…”

“…Gaylarde and Gaylarde (2000) found algae, cyanobacteria, protozoa, fungi, slime, moulds, actinomycetes and other bacterial groups on surfaces of painted buildings in five Latin American countries (a total of 1363 different morphotypes were found by the authors). These authors suggested that there are approximately 4 x 10 6 species of phototrophs on painted walls throughout the world.…”

“…Some fungi, for example, can be associated with problems such as allergenic diseases, disorders of the skin and respiratory problems (Gutarowska and Zahowska, 2002;Shirakawa et al 2002a and2002b). As the biodiversity of painted building surfaces can be very high (Gaylarde and Gaylarde, 2000), it is necessary to develop biocides with a broad range of action and ever greater efficiency, but with less toxic effects.…”

-Biocides play an important role in the preservation of a variety of products susceptible to microbiological growth such as paint, a material that can undergo microbial deterioration both in storing (inside the can) and after the application on a surface. In this work, artificial neural networks were used to predict the level of fungal growth on surfaces painted with water-based paints with biocide formulations containing different concentrations of ten kinds of commercial and experimental chemical agents. The use of neural networks is well known in chemical processes and they are a powerful tool for discovering relationships between sets of data. Industrial Environmental Tropical Chamber tests were used as the network training set. The importance of the each additive of the dry-film biocide formulation in prevention of biodeterioration was also examined.

-(Corticolous green algae from tropical forest remnants in the northwest region of São Paulo State, Brazil). The algae inhabit a wide variety of terrestrial environments and substrates; however the taxonomic knowledge for tropical regions is still scarce. This survey was conducted in ten forest remnants in São Paulo State where visible growths of algae and bryophytes were collected and studied for the main algal components of the communities. Results reveal the occurrence of nine species of green algae, distributed through the class Trebouxiophyceae (one species), Charophyceae (one species) and Ulvophyceae (seven species). Desmococcus olivaceus (Persoon ex Archerson) J. R. Laundon and Printzina effusa (Krempelhüber) Thompson & Wujek are new records for Brazil. The most frequent organisms found in the areas pertain to Trentepohliales that is mainly represented by Trentepohlia species. On the basis of results found, it is recommended that such communities receive more attention in future investigations to improve the knowledge about this important group of primary producers.Key words -Brazil, seasonal semideciduous forest, terrestrial algae, Trentepohlia RESUMO -(Algas verdes corticícolas de remanescentes de fl oresta tropical na região noroeste do Estado de São Paulo, Brasil). As algas habitam uma grande variedade de ambientes e substratos terrestres; entretanto o conhecimento taxonômico para as regiões tropicais ainda é escasso. Esse levantamento foi conduzido em 10 fragmentos fl orestais no Estado de São Paulo, onde crescimentos visíveis de algas e briófi tas foram coletados e os principais componentes da comunidade algal foram estudados. Os resultados revelaram a ocorrência de nove espécies de algas verdes, distribuídas nas classes Trebouxiophyceae (uma espécie), Charophyceae (uma espécie) e Ulvophyceae (sete espécies). Desmococcus olivaceus (Persoon ex Archerson) J. R. Laundon e Printzina effusa (Krempelhüber) Thompson & Wujek são novos registros para o Brasil. Os organismos mais frequentes nas áreas pertencem a Trentepohliales, que foi representado principalmente por espécies de Trentepohlia. Baseado nos resultados encontrados, é recomendado que tais comunidades recebam mais atenção em investigações futuras para aumentar o conhecimento sobre esse importante grupo de produtores primários.Palavras-chave -algas terrestres, Brasil, fl oresta estacional semidecidual, Trentepohlia 1.
