What About Biofilms on the Surface of Stone Monuments?
Bacteria can live either as free planktonic cells in bulk solution, or as sessile cells attached to a surface. In addition to their attachment status, sessile bacteria are part of sessile communities termed biofilms. A biofilm can be defined as a microbial community attached to a solid surface composed of cells organized as microcolonies embedded in an organic polymer matrix of microbial origin...
متن کاملBiofilms and lichens on stone monuments: do they damage or protect?
With this paper, I focus on a topic that, in my opinion, is worth consideration by scientific community involved in the conservation of cultural heritage. As far the role that biofilms and lichens play in the weathering of natural and artificial stones, an increasing number of researches account for a negligible effect and even for a protection. Thus, the axiomatic correlation among biofilms, l...
متن کاملMathematical Models for Biofilms on the Surface of Monuments
In this article, a system of nonlinear hyperbolic-elliptic partial differential equations is introduced to model the formation of biofilms. First, a short introduction to some basic concepts about biofilms is given. Then a detailed derivation of the model is presented, which is mainly based on the theory of mixtures, also in comparison with previous models. Adapted numerical schemes will be pre...
متن کاملCharacteristics and role of the exocellular polysaccharides produced by five cyanobacteria isolated from phototrophic biofilms growing on stone monuments.
Three coccoid and two filamentous cyanobacterial strains were isolated from phototrophic biofilms exposed to intense solar radiation on lithic surfaces of the Parasurameswar Temple and Khandagiri caves, located in Orissa State, India. Based on to their morphological features, the three coccoid strains were assigned to the genera Gloeocapsosis and Gloeocapsa, while the two filamentous strains we...
متن کاملBiodeterioration of Stone Monuments a Worldwide Issue
The biodegradation is a general action strictly linked in the presence of active organisms, and this is not only unavoidable but it represents a fundamental process of the Biosphere. When this process is acting on « valuable » objects, is named as Biodeterioration. The consequences surely produce a worse condition, and this process is particularly unfavourable when the object belongs to the Cul...
