“…The antifungal activity was studied with the help of silver ions. Silver is a potentially toxic metal to most of the microorganisms, that interact with cellular nucleic acids and enzymes active sites or absorbs on the all wall (Heaton et al, 1991). Similarly in the present study reported that, the antifungal activity was determined with different concentration of silver nitrate (50, 100 & 150 ppm) by using agar well diffusion method.…”

Paintings are essential components of culture heritage all over the world. Paints consist of organic and inorganic nutrients that can stimulate the growth of the microorganism. Many of the components present in paint are biodegradable. Paint is used for the protection of the substrate materials. The purpose of paint is to provide good appearance. Paint is a surface coating polymer based products. It is often discoloured by mould and blue stain, this leads to loss of paints. Biodeterioration arise from interaction among substrate, environment and organisms. The fungi degrade the paint film by producing extracellular enzymes such as ligninase, cellulose and organic acids. The most commonly used method is the addition of antifungal agent in the paint composition, which may acts as a biocide and inhibits the mould growth on paint and painted surface. Therefore the present study was aimed to isolate and identified the mouldy growth on fabric paints especially in green and red colors. The effective control of fungi in the paints was controlled using appropriate antifungal agent. Silver nitrate is very effective in killing fungal species that causes decay and deterioration of paint or paint film even at low concentration.

“…People who cannot prevent the occurrence of the mould problem, they need to resort to chemical agents, special plasters and anti mould paint or major flat renovation. Because fungi are very difficult to get rid of if they have grown deep into various materials, including plasters on the walls and ceilings of the rooms [25,26]. It is also possible to use physical methods to preventing and combating attacks of fungus as well as other harmful living organisms (e.g.…”

The development of indoor molds is mainly connected to the room conditions, like air humidity, temperature or pH. The sanitary rooms, usually with elevated dampness, are a good environment for fungal growth and should be monitored for fungal concentration due to the risk of an elevated exposure to fungal allergens and mycotoxins. In the present work the diversity and the concentrations of fungal pollutants in the dormitory bathroom of Polish University was evaluated for both the ceiling and the air. The results showed that Cladosporium cladosporoides was the only species found on the dark stains on the ceiling, but in the air the variety of fungi was higher, with a total of 6 species: Aspergillus flavus, A. niger, C. cladosporioides, Fusarium poae, Penicillium chrysogenum and Rhizopus nigricans. The increased concentration of A. niger and C. cladosporoides in the air suggests further control of the air pollution in order to avoid excessive exposure to mycotoxins and allergens. Moreover, the concentration of airborne fungi inside the facility exceeded some standards of fungal air contamination stated as dangerous for human health. Our study allows for unambiguously identifying isolated fungi and develop recommendations, to prevent the present outbreak of fungi as well as in the future.

“…One of these strategies is the application of coatings (Ivanovna et al, 2016). Paints and varnishes are coatings with a decorative or protective function that can be complemented with antimicrobial compounds such as algaecides (Gladis et al, 2010), bactericides (Hoque et al, 2015) and/or fungicides (Heaton et al, 1991).…”

Pyocyanin is a pigment produced by 95% of Pseudomonas aeruginosa strains and exhibits antimicrobial properties that can be used for different purposes. In this work, PMMA-based nanoparticles that were encapsulated into 200 µg/mL of pyocyanin (Np-Pyo) were produced by the nanoprecipitation method. They were evaluated with respect to antifouling activity against Aspergillus sp. and Penicillium sp. With an encapsulation efficiency of 56%, the NpPyo remained stable for 90 days. Their characteristics were satisfactory for the following parameters: average size (616.90±38.30 nm; blank: 282.58±22.89 nm), polydispersion index (0.51±0.01; blank: 0.45±0.78), zeta potential (-5.13±0.41 mV; blank: -6.44±1.12 mV) and pH (6.18±0.03; blank: 6.42±0.01). The in vitro biofilm formation assay was performed on dolomite coupons measuring 1 cm2, on which the formulation was applied. There were tested conditions with and without immersion for 72h at 30 ºC. In the tests with the immersed coupons, there was fungal colonization; this was, however, lower than that observed in the control. A. niger decreased by 3 log units. No growth was observed on the coupons that were not immersed. The results were promising and demonstrated viability as a means of antifouling protection, particularly on dry surfaces.
