Aims: The effects of plasterboard composition on Streptomyces californicus growth and bioactivity of spores were studied. Methods and Results: Streptomyces californicus was grown on 13 modified plasterboards under saturated humidity conditions. The total content of fatty acid methyl esters was used for quantifying S. californicus biomass, while the spore-induced cytotoxicity and production of nitric oxide (NO), tumour necrosis factor-alpha, and interleukine-6 (IL-6) in mouse macrophages was used to assess the bioactivity of spores. Removal of starch completely from the plasterboard or only from the core reduced significantly the biomass production and the biological activity of spores in comparison with reference board. The biocide added into the core or on the liner decreased the growth markedly and inhibited the sporulation totally. The biomass production correlated positively with the spore number, cytotoxicity, and production of NO and IL-6. Conclusions: Streptomyces californicus grew under nutrient limitation on all studied plasterboards. The starch is the major factor enabling S. californicus to grow and to produce biologically active metabolites on plasterboard. Significance and Impact of the Study: The composition of building material has an impact on microbial growth and bioactivity of spores which may be involved in complex mechanisms leading to respiratory symptoms in the occupants in moisture damaged buildings.

Microbial growth and the production of volatile metabolites is one possible explanation for building-related health problems. Streptomyces spp. are frequently found in water-damaged buildings. This study shows that Streptomyces spp. are able to produce not only odorous compounds like geosmin, but also potentially irritating compounds. This finding should be of interest in indoor air investigations.

“…The most dominant bacteria were Streptomyces and Pseudomonas, whose species tend developing in water damaged buildings and can be a serious threat to human health causing respiratory problems among others [16,17]. In addition, the bacteria from the highly diverse phylum Firmicutes were found on all three samples.…”

Silver Nanoparticles Study for Application in Green Housing

We report on antibacterial and antifungal properties study of silver nanoparticles in applications relating to straw bale construction. Humidity related growth of microorganisms in green constructions is of concern as it can induce health problems among the house residents and also can cause lower durability of ecologically friendly construction materials. We provide a comparative analysis of the effects of silver nanoparticles on most common house-colonizing fungi and bacteria. Outdoor tests demonstrated an efficiency of the silver nanoparticles for fighting micro-organisms. Indoor tests in petri dishes were then performed and compared with outdoor tests and the possible nature of the biocidal properties of the silver nanoparticles is probed. In contrast to the commonly reported results, we observe that antifungal properties of silver nanoparticles against common fungi in outdoor conditions show great potential in related applications.
