Examination of fungal deterioration on plasticized polyvinyl chloride by cryo-scanning electron microscopy

Cladosporium as the Main Fungal Contaminant of Locations in Dwelling Environments.

“…Phoma was isolated from 24 locations (35.3%) of which 10 were highly contaminated. This fungus is known to be the main contaminant of environments like bathrooms that are wet or moist (Moriyama et al, 1992 and1993). Our findings were the same as those of other reports that showed Phoma was dominant.…”

Microbial deterioration of Mowilith DMC 2, Mowilith DM5 and Conrayt poly(vinyl acetate) emulsions used as binding media of paintings by pyrolysis-silylation-gas chromatography–mass spectrometry

“…Thus, study of the biodeterioration of synthetic binders and varnishes has attracted the attention of the conservation profession given their demonstrated ability for undergoing morphological and chemical changes on microbial attack. Thus, different methods have been reported for assessing the biodeterioration of synthetic resins commonly present in paintings, sculptures and other contemporary art objects including instrumental techniques such as optical and scanning electron microscopy (SEM) [7][8][9], spectrophotometry [8,9], determination of the weight loss of specimens inoculated with Evaluation of the deterioration produced by microbiological attack on Mowilith DM5, Mowilith DMC2 and Conrayt poly(vinyl acetate) (PVA) emulsions has been carried out using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The proposed method includes the on-line derivatization of PVA emulsions using hexamethyldisilazane during pyrolysis.…”

Biodegradation of thermally treated low density polyethylene by fungus Rhizopus oryzae NS 5

“…3a, b. Mathur et al (2011) the microbial adhesion to the surface of polymer is a preliminary step for biodegradation to take place (Moriyama et al 1993). Microorganisms colonize the polymer surface and adhere by extracellular polymer production.…”
