Air pollutants, such as nitrogen oxides (NO and NO2), have a negative impact on the built cultural heritage. In order to reduce it, a photoactive repair plaster for conservation of various gypsum decorations, in particular moulded elements, has been developed in compliance with the requirements of conservators-restorers international community. Hen...

Relatively easy treatment of glass aggregates can lead to the formation of a highly porous zeolite aggregate. This study focuses on the possibility of using such an aggregate as an active additive to a gypsum binder. The physical properties of hardened gypsum composites with zeolite fillers doped with various metal ions (Ni2+, Cu2+, and Zn2+) have...

In 2017-2020, the Pontifical University of John Paul II undertook the project of the chapter house heritage conservation financed from EU funds: Konserwacja unikatowych w skali światowej zabytków związanych z historią Krakowskiej Kapituły Metropolitalnej oraz udostępnienie ich w przestrzeni wystawienniczej w postaci interaktywnej multimedialnej eks...

The prevention of decrease of quality caused by microbial activity in footwear materials entails the use of biocides. However, these substances may pose a hazard to humans and to the natural environment. The paper presents the results of antimicrobial effect investigation for cowhide leather treated with oregano oil. In these studies oil was applie...

Essential oils introduced into raw materials in the technological process enable leather to gain antimicrobial properties. These properties were examined toward microorganisms potentially pathogenic to humans and causing biodegradation of leather. The article presents an assessment of antimicrobial activity of cowhide lining leathers fatliquored wi...

The main purpose of these studies was to assess the possibility of applying the technique of solid phase microextraction (SPME)-gas chromatography (GC)-mass spectrometry (MS) to detect the activity of moulds on historical objects, based on the analysis of microbial volatile organic compounds (MVOCs). The studies were performed for selected species...

The goal of this work was to analyze the profile of microbial volatile organic compounds (MVOCs) emitted by moulds growing on silk samples in search of particular volatiles mentioned in the literature as indicators of active mould growth. The selected moulds were inoculated on three types of media: (1) samples of pure silk placed on microbial media...

The goal of this work was to analyse the profile of microbial volatile organic compounds (MVOCs) emitted by moulds growing on parchment samples, in search of particular volatiles mentioned in the literature as indicators of active mould growth. First, the growth of various moulds on samples of parchment was assessed. Those species that showed colla...

The goal of this work was to determine the microbial volatile organic compounds emitted by moulds growing on wool in search of particular volatiles mentioned in the literature as indicators of active mould growth. The keratinolytically active fungi were inoculated on two types of media: (1) samples of wool placed on broths, and (2) on broths contai...

The main aim of the research was to evaluate the microbiological quality of the deacidification solution produced by GSK company. The solution is used in Neschen C900 machines in two institutions (1 and 2) in Poland for deacidification of paper collections. Tests were performed for two types of samples: the working solution, located in the tub of t...

The evaluation of the laundering process requires microbiological cleanness testing. There are no clearly established methods for determining the number of microorganisms surviving in fabrics after washing. The aim of the study was to evaluate the number of bacteria surviving the laundry process in textiles stained with blood. Cotton textile sample...

The main goal of this work was to optimize the SPME sampling method for measuring microbial volatile organic compounds (MVOCs) emitted by active molds that may deteriorate historical objects. A series of artificially aged model materials that resemble those found in historical objects was prepared and evaluated after exposure to four different type...

DNA isolation is a crucial step of conducting genetic studies in any organism. However, this process is quite difficult when studying fungi because of the need to damage the fungal cell walls of specific structures. In this study, we developed a method for the rapid and efficient isolation of fungal DNA based on simultaneous mechanical and enzymati...

The bioluminescence method is based on measurements of adenosine triphosphate (ATP) which is the principal energy carrier in all living organisms, including microorganisms. ATP reacts with luciferin in the presence of the catalyst -luciferase enzyme, and the effect of this oxidation reaction is emission of light, recorded by a luminometer. In hygie...

Ocena efektywności procesu prania wymaga sprawdzenia czystości mikrobiologicznej. Nie ma jednoznacznie ustalonych sposobów wyznaczania liczby drobnoustrojów pozostających w tkaninach po praniu. Celem badań było określenie liczby bakterii przeżywających proces prania w zabrudzonych krwią tkaninach. Próbki tkaniny bawełnianej zaszczepiano trzema...

Nanoparticle preparation with metal compounds, especially silver ones, is nowadays very often applied to give technical materials antibacterial properties. The aim of these studies was to evaluate the antimicrobial efficiency of zinc dioxide after it incorporation onto cotton and polyester textiles. Fabrics were treated with water suspension nanoca...
