Bacteria of the pseudomonas migula genus on stored vegetables

Acta Scientiarum Polonorum: Hortorum Cultus, 2003
For the study on Pseudomonas bacteria, samples of vegetables with soft rot symptoms were collected in a market place and storage-rooms. The samples were examined on selective media for Gram-negative bacteria of the genus Pseudomonas.

Biodeterioration of cementeous matrix by fungi // Biodeterioration d'une matrice cimentaire par les champignons [PDF]

, 2007
International audienceBiodeterioration mechanisms are complex and not yet absolutely understood. To control and to act efficiently against deterioration by fungi, it is necessary to have a better understanding of those mechanisms.

Uncovering the Fungal Diversity Colonizing Limestone Walls of a Forgotten Monument in the Central Region of Portugal by High-Throughput Sequencing and Culture-Based Methods

Applied Sciences, 2022
Fungal organisms are considered one of the most relevant stone colonizers, and biodeteriogens. They are ubiquitous heterotrophs, metabolically versatile, ranging from generalist to extremophiles. Limestone, a sedimentary rock characterized by high levels

The Roman Houses of the Caelian Hill (Rome, Italy): Multitemporal Evaluation of Biodeterioration Patterns

Microorganisms, 2023
Like other hypogeal environments, the Roman Houses of the Caelian Hill are prone to unwanted biological growth. Wide conservative interventions have been carried out at the beginning of this millenium to reduce biodeterioration and physical–chemical ...

A role for microbial selection in frescoes' deterioration in Tomba degli Scudi in Tarquinia, Italy [PDF]

, 2017
Mural paintings in the hypogeal environment of the Tomba degli Scudi in Tarquinia, Italy, show a quite dramatic condition: the plaster mortar lost his cohesion and a white layer coating is spread over almost all the wall surfaces.

The Integration of Metagenomics and Chemical Physical Techniques Biodecoded the Buried Traces of the Biodeteriogens of Parchment Purple Spots

Frontiers in Microbiology, 2020
Ancient parchments record an immense part of our cultural heritage, having been used as the main written support material for centuries. Parchment easily undergoes biodeterioration, whose main signs are the so-called purple spots, which often lead to ...
