“…Comparing the isolated microflora from these two albumen prints with those from similar items, for example gelatin-based photographs 6 7 8 9 10 , shows that there are some common members from the Bacillus , Aspergillus and Penicillium genera. Several fungi, such as Pleurotus pulmonarius , Phlebia sp., Pleosporales sp.…”

“…and Malassezia sp.) were detected in both the album and the Gyula print, although the fungal community of the albumen print was richer, containing many other species, several of which, Trichosporon , Geotrichum / Galactomyces , Chaetomium and Cladosporium , have already been found in photographic materials or archival documents 6 10 44 45 . Fungal species of the genera Nectria , Corynespora and Saccharomyces were also seen, which have not frequently been encountered in archival environments.…”

“…Many albumen-based photographs must exist in archives, galleries and museums around the world, both on display and in storage, and several of them are part of important historical collections; like the other historical objects in these collections, they too need to be safeguarded against aging and biodeterioration processes. It is already known how many microorganisms, mainly fungi, attack various types of archival materials, including books, parchments and photographic materials 3 4 , but, though many studies have been carried out to investigate the microflora responsible for the deterioration of different materials preserved in indoor environments 3 4 5 , few have examined the biodeterioration of photographic materials, and most of those that do have focused only on gelatin-based photographs 6 7 8 9 10 .…”

This study is one of the few investigations which analyze albumen prints, perhaps the most important photographic heritage of the late 19th and early 20th centuries. The chemical composition of photographic samples was assessed using Fourier-transform infrared spectroscopy and X-ray fluorescence. These two non-invasive techniques revealed the complex nature of albumen prints, which are composed of a mixture of proteins, cellulose and salts. Microbial sampling was performed using cellulose nitrate membranes which also permitted the trapped microflora to be observed with a scanning electron microscope. Microbial analysis was performed using the combination of culture-dependent (cultivation in different media, including one 3% NaCl) and culture-independent (bacterial and fungal cloning and sequencing) approaches. The isolated microorganisms were screened for their lipolytic, proteolytic, cellulolytic, catalase and peroxidase activities. The combination of the culture-dependent and -independent techniques together with enzymatic assays revealed a substantial microbial diversity with several deteriogen microorganisms from the genera Bacillus, Kocuria, Streptomyces and Geobacillus and the fungal strains Acrostalagmus luteoalbus, Bjerkandera adusta, Pleurotus pulmonarius and Trichothecium roseum.

“…Photographs are composed of at least three components: a rigid metal-free paper support, an image-forming material and a binder that in 20th century photographs is mainly based on gelatin, whereas in the late 19 th and early 20 th cent. albumen prints were also used [1]. A layer of barium sulphate (baryta paper, BaSO4) is placed between the gelatin and paper layers in order to increase the light reflection coefficient [18,19].…”

“…Photographs and films, popularly referred to as "the seventh art", represent an ethnographic, social and artistic [1] narrative of life events [2] as part of humanity's historic and cultural heritage and, as such, need to be conserved for future generations. In the digital era, taking a picture is trivial with a modern digital camera, but until the last decade of the 20th century, it required considerable skill, and photographs had to be developed using a special light-sensitive emulsion [3].…”

Overview of fungal isolates on heritage collections of photographic materials and their biological potency

Despite controlled relative humidity in archives and private collections, fungi are a widespread cause of biodeterioration of cinematographic films and historic photographs, which represent a significant cultural and historic loss to society. Photographic emulsions and coatings are organic and hygroscopic in nature and represent a good and easily accessible source of nutrients. Because archives hold whole stacks of these materials, they subsequently contain more fungi in comparison to other enclosed spaces. This in turn generates a need for a systematic microbiological evaluation of fungi isolated from photographic documents in order to pinpoint the potentially biodeteriorative fungal species and increase awareness and control readiness when these species are encountered.With this aim, we have decided to collect data regarding fungal isolates and their biological potency from the following originating materials: gelatin cellulose triacetate or cellulose nitrate films, albumen or gelatin paper photographs, cellulose nitrate negative films, gelatin glass plate negatives and positive paper prints. In addition, the most efficient biotic degraders of gelatin binder are presented and the degradation of cellulose based supports as well as the occurring microbial interactions and the impact of inhibitory silver salts are reviewed. Lastly, based on the origins of fungal contamination and the occurrence of fungi related to allergenic and toxicogenic diseases, prevention and control measures are suggested.

Microbial deterioration accounts for a significant percentage of the degradation processes that occur on archeological/historical objects and artworks, and identifying the causative agents of such a phenomenon should therefore be a priority, in consideration of the need to conserve these important cultural heritage items. Diverse microbiological approaches, such as microscopic evaluations, cultural methods, metabolic- and DNA-based techniques, as well as a combination of the aforementioned methods, have been employed to characterize the bacterial, archaeal, and fungal communities that colonize art objects. The purpose of the present review article is to report the interactions occurring between the microorganisms and nutrients that are present in stones, bones, wood, paper, films, paintings, and modern art specimens (namely, collagen, cellulose, gelatin, albumin, lipids, and hydrocarbons). Some examples, which underline that a good knowledge of these interactions is essential to obtain an in depth understanding of the factors that favor colonization, are reported. These data can be exploited both to prevent damage and to obtain information on historical aspects that can be decrypted through the study of microbial population successions.
