Carlile & Watkinson (1994) states that the number of species of fungi that have been identified by the year 1994 reached 70,000 species, with an estimated addition of 600 species each year. Of these, about 10,000 species of the fungus. According Moncalvo (1997) and Kuhn & Ghannoum (2003), most species of fungi found in tropical regions due to local climatic conditions are warm and humid torpis that supports growth. Fungi are very diverse habitats, but in general, mold can grow on substrates containing organic carbon sources (Carlile & Watkinson 1994).
Molds that grow and colonize the parts in the room has been studied. Mold is easily found on parts of the room is damp or wet, such as the former ceiling is leaking, the walls are dirembesi water, or on damp furniture that is rarely exposed to sunlight. Genus of fungi are often found growing in the room were Cladosporium, Penicillium, Alternaria, and Aspergillus (Mazur et. Al., 2006). Another study conducted by Brasel et al. (2005) showed that the fungi of the genus Stachybotrys is also found growing indoors.
Mold spores can cause health problems will primarily attack the respiratory tract. Asthma, allergic rhinitis, and sinusitis is the most common health problems encountered as a result of the immune system that attack the spores are inhaled (Curtis et al., 2004; Mazur et al., 2006). Another disease is the fungus infection of the respiratory tract, or so-called mycosis. One common disease is Aspergillosis mycosis, which is the growth of fungi of the genus Aspergillus in the respiratory tract (Soubani & Chandrasekar 2002). In addition to the genus Aspergillus, several species of the genus Curvularia and Penicillium can also infect the respiratory tract and showed similar symptoms such as Aspergillosis (Mazur et al., 2006).
