“…As the conventional fungicides are not suitable for indoor usage, more environmental friendly compounds that are non-toxigenic to humans are required [4] . A few biocides used in the food industry have been evaluated and shown to be effective against isolated indoor waterborne fungi [4] , [5] , [6] , [7] , [8] , [9] and single isolated indoor airborne fungus [9] . Nevertheless, the techniques used in the previous method focused on evaluation of bioactive compounds against single isolated fungus by taking into consideration that the fungus growth is measured by diameter of fungus colony, which is very hard to measure, and required 30 days to accomplish [4] .…”

“…Potassium sorbate was used as an example of the subject of the assay in this study because of its previous performance in controlling the growth of individual indoor fungus [4] , [5] , [6] , [7] , [8] , [9] . However, this method could be used to assess the biocide inhibitive performance of other new alternatives/bioactive compounds against the total indoor airborne fungi.…”

“…The antifungal used should be effective in controlling the fungi growth and safe consumed as concerns rises on the safety of the chemicals used [9]. Antifungal such as potassium sorbate, calcium benzoate and zinc salicylate is safe as food preservatives [1,[10][11][12]. Therefore, this research conducted to investigate the ability of these antifungal to reduce the growth of indoor fungi on four dif-ferent types of wall finishing.…”

Various health complaints often been attributed to pollution and the poor quality of the indoor air. If there is good practice in building design, construction, and maintenance, the structures should remain dry. However, when there is moisture damage, the materials may be in contact with water for prolonged times, which inevitably leads to microbial growth or even total deterioration of the building material. Antimicrobial coating is designed to generate a surface that is easy to clean and can also incorporate active agents, commonly called antifungal, that prevent microbial colonization, the subsequent growth and bio-deterioration of the substrate. This paper presents the sustainable treatment for indoor environment quality in buildings by examining the application of potassium sorbate, zinc salicylate, and calcium benzoate that used as food industry preservatives as indoor antimicrobial agents. Four types of wall finishing used on plasterboard substrate: acrylic paint, glycerol based-paint, thin wallpaper, and thick wallpaper. The result indicated that potassium sorbate is the best bio compound to react as antifungal agent to prohibit the growth of indoor fungi. All the antifungal shows difference level of their effectiveness from each other. Only 40% of fungi were able to grow on thin wallpaper by using potassium sorbate as antifungal agent.

“…This is an area where a hazard such as chemicals, lighting and indoor air quality rises. Health problems such as asthma, irritations and other issues are spread due to airborne fungal spore which effect humans drastically [5][6][7]. These signs are uncommon in buildings that are well maintained but water leaks and inappropriate humidity levels causes high fungal spore loads [8,9].…”

Abstract. Buildings are a vital component in a human's daily life. It provides shelter from the environment, weather and animals. Mold growth within the building might be caused by the moisture problems which directly act on it such as water leaks or indirect factor such as high humidity levels. This growth causes esthetic problems and deterioration of its wall coatings. Spores from the fungi also cause health problems to humans. The fungus species studied in this research is Aspergillus niger. The material is made of wood and its finishing is thick wallpaper, thin wallpaper, acrylic paint and glycerol based paint. ASTMD5590-00 standard was used to evaluate fungal growth and to determine if non antifungal agent was effective in inhibiting the amount of fungal growth on four types of wall finishing used on wooden walls. This research was conducted without using any antifungal agent. Highest percentage of growth of the fungi was found on acrylic paint, followed by glycerol based paint and thin wallpaper. Thick wall paper shows the least growth of fungi. The maximum growth is visible on day 12 which is more than 60% by all the wall finishing.
