“…The brown discoloration of paint surfaces has been reported to originate from minerals, fungi, and specific cyanobacteria [48]. In addition to microorganisms, the EPS in biofilm not only adheres to cells but also traps atmospheric dust and carbon residues from automobile traffic and pigments and minerals produced by microorganisms and contributes to the discoloration of buildings [49,50].…”

Microbial colonization leads to the formation of biological soil crusts (BSCs) on the surface of architecture, which causes the deterioration of construction materials. However, little information is available on the formation of BSCs on lime concrete materials of early architecture. In this study, the variances of microbial communities, physicochemical properties, and surrounding environmental factors of the lime concrete facades from the early architecture of Wuhan University were investigated. It was found that the surface of lime concrete materials was internally porous and permeable, embedded with biofilms of cyanobacteria, mosses, bacteria, and fungi. Redundancy analysis (RDA) analysis showed that the abundances of photoautotrophic microorganisms depended on light intensity and moisture content of construction materials, while that of heterotrophic microorganisms depended on total nitrogen (TN) and NO3−-N content. The deposition of total carbon (TC), NH4+-N, and total organic carbon (TOC) was mainly generated by photoautotrophic microorganisms. The lime concrete surface of early architecture allowed internal growth of microorganisms and excretion of metabolites, which promoted the biodeterioration of lime concrete materials.

“…The recent study extended the significance of digitalization that enriched cultural to digital heritage in the European country and how digital takes much dynamic the stimulating and participating familiarity in museum or gallery exhibition. The recent study enhanced more towards scientific approaches within chemistry (Alexander & Schiesser, 2017). Moreover, even though in India, the status of digitization has been explored, which works closely with manuscripts in India.…”

This project reviewed on the artwork that exhibited in galleries is always in danger of being deteriorated due to exposure or the unconducive environment unless a good system of preserving them is in place. The valuable artwork must protect, and therefore a useful archiving technology needs to be engaged for the perpetual digitalized artwork. This project was able to digitalize for constant archiving of artwork that contains various themes, styles, content and context from a different medium. The identification is essential due to categorizing the types of material, including physical and visual protection through digitations.

Biofilm formation is a serious problem in the food industry due to spoilage bacteria colonization. The main spoilage bacteria of postharvest vegetables are Erwinia and Pseudomonas species (Lone Gram et al., 2002). These bacteria form biofilms on the surface on which they colonize, thereby providing shelter for antimicrobial agents and other sanitation procedures (Claessen et al., 2014;Yu et al., 2021). Biofilm formation is considered a stagewise process. Firstly, planktonic bacteria move to the surface mediated by flagellum, where they may then attach reversibly and the initial adherence of bacterial colonists to a surface is through weak van der Waals forces. After enough cells adhere to the solid surface, the bacteria begin to secrete extracellular substances, such as exopolysaccharide (EPS), to anchor themselves more enduringly. The biofilm can further develop and mature with the protection of the
