Biodegradation, Biodeterioration, and Biostabilization of Industrial Products

Waterborne functional paints to control biodeterioration

“…There are biocides that result to be functional in dry films (in-film) while others seek it in the liquid product (in-can). In the last decades, the concern about the environmental impact of biocides has led to new legislations with restrictions on the use of compounds such as aromatic and halogenated derivatives while others are no longer allowed, as is the case of phenylmercurials [65]. Nowadays, due to different regulatory requirements and to achieve a broader range of activity, the trend in most countries is to combine active ingredients to obtain more effective ("booster") biocide compositions to formulations [66].…”

“…Resins with ester bonds like some polyurethanes have been found to be more susceptible to microbial attack and experience more in-service failure than those based on polyether because of the susceptibility of the ester to a large number of microbial enzymes (the hydrolases) [75]. In the case of additives conformed by small molecules, they are most easily affected, and although they are in lower concentration, their degradation can cause important losses in the functionalities of the coating systems and therefore affect their performance [65].…”

Effect of Microorganism on Flax and Linen

“…[1]. Microorganisms attack on any kind of fibre or material surface in various steps like 1) Microorganisms stick onto the surface of a material either by adhesion or aggregation, 2) proliferation of attached microbial cells, 3) production of enzymes, 4) biodegradation of materials, 5) reduction of degree of polymerization of material polymer and production of degradable products [2].…”

“…Biofragmentation is a process in which microorganisms increase their population and secrete enzymes and free radicals, which break down macromolecules to oligomers and monomers. In assimilation, energy, new biomass and various metabolites used by microorganisms are produced and simple gaseous molecules and mineral salts are released into the environment [2].…”

Organo-montmorillonite with biogenic compounds to be applied in antifungal coatings

“…Aspergillus fumigatus is an example of an opportunistic pathogen which causes a wide spectrum of problems related to the respiratory system including life-threatening infections in immunocompromised patients (Kousha et al, 2011;Lee et al, 2013). Hygienic coatings are formulated to control indoor microbial growth in households and health care centers among other (Falkiewicz-Dulik et al, 2015;Johns, 2003). Their study is very active at the present, specially the seeking of new eco-friendly bioactive additives or microbiocides to replace those questioned due to their toxicity and low efficiency.…”
