Microbiological and entomological analysis
Microbiological and entomological analyzes for archives, libraries and museums
Archives, libraries and museum deposits are places naturally exposed to the risk of biological attacks. Molds, bacteria and insects can proliferate in conservation environments and damage, even irremediably, the archival and book heritage for various reasons. The most important are: the alteration, even for a short period of time, of the correct microclimatic storage parameters (in particular temperature and relative humidity); the presence of dust deposits attributable to the failure to carry out maintenance activities at regular intervals; the acquisition of contaminated works, funds or collections; the excessive anthropogenic impact on the part of visitors and users; the lack of barriers and filters to control external pollution; the operation of uncleaned and unmaintained air conditioning systems.
A high risk of infections is also associated with the occurrence of micro-disasters – such as ruptures of pipes and pipes, infiltrations, etc. -, or major catastrophic events – such as floods, fires and consequent shutdowns, earthquakes. The contact of archival and library assets with water, even for a few hours, is in fact sufficient to induce the development and propagation of molds, fungal spores and bacteria capable of irreversibly deteriorating paper or membranous supports.
In addition to the certified sanitation, disinfection and disinfestation activities – carried out both on site and in the company, through a unique fleet of machines in Italy – Fratielivi offers its customers a series of laboratory services provided by professionals. These services are dedicated to the recognition, eradication and contrast of biodeteriogens and focused on diagnostics, control, monitoring and prevention.
The characterization of biological degradation and the certification of the results of the disinfection and disinfestation procedures
Before starting the disinfection, disinfestation (and restoration) operations, it is good to know and define the origin of the problem in order to implement the most correct intervention strategy. To precisely define the quantity and vitality of infectious agents and infesting organisms, as well as their degree of danger to the artistic-cultural asset to be protected and, in some cases, to human beings, Fratielivi makes use of the intervention and the skills of some professional figures. In particular, conservation scientists and microbiologists belonging to the order and experts in the preparation and conduct of appropriate laboratory tests for movable cultural assets of archival, library and museum interest.
These examinations and laboratory tests are always conducted or carried out through: non-invasive sampling and, in the case of insects, through appropriate capture with entomological traps; instrumental microscopic, biochemical, cultural and, in some cases, DNA investigations. These performances allow:
- the determination of the bacterial and fungal load
- the determination of the microbial activity
- the taxonomic recognition of biodeteriogenic microbial species
- the recognition of the entomological weeds species (woodworms, termites, silverfish, moths, etc.)
Monitoring of conservation environments: investigations, techniques and tools for preventive conservation
To effectively combat the development of mold and insects in archives, libraries and museums, a series of preventive measures can be adopted. They can contribute both to slowing down the natural degradation of archival and library assets, and to reducing the costs of any restoration work. The focus of the solutions offered by Fratielivi in this area is the conservation environment.
The protection actions proposed by the company include:
- air quality analyzes
- aerobiological investigations
- entomological monitoring
- microclimatic monitoring through dataloggers
- the supply of systems for the restoration and maintenance of optimal hydroclimatic conditions
The solutions offered by the company for preventive conservation include, upon request, the supply of certified containers for long conservation. These containers, produced, even custom-made, by the Fratielivi paper converting division, allow the reconditioning of sanitized and disinfected paper and membranous material in accordance with the law.
