Due to the ongoing threat of degradation artefacts and monuments, conservation cultural heritage items has been gaining prominence on global scale. Thus, finding suitable approaches that can preserve these materials while keeping their natural aspect is crucial. In particular, preventive an approach aims control deterioration before it happens in order decrease need for intervention. Several techniques have developed this context. Notably, application coatings made metal oxide nanomaterials dispersed polymer matrix be effectively address stone issues. (TiO2, ZnO, CuO, MgO) with self-cleaning antimicrobial activity considered as possible conservative materials. Metal used strengthen several studies. This review seeks update knowledge different kinds nanomaterials, especially nanoparticles nanocomposites, employed preservation consolidation over last 10 years. transport diverse environments undoubtedly not well understood. Therefore, controlling effects various neighbouring non-target organisms ecological processes

Abstract An arsenite-oxidizing bacterium was isolated from the Ganga River, Varanasi, India. Phylogenetic analysis by 16S rRNA gene sequencing identified strain as Kurthia gibsonii MKVVM3 IITBHU. The bacterial growth showed biofilm formation in As (V) containing medium. oxidized 100 mg l −1 of (III) to initial 24 h incubation. In first two days, arsenite oxidase amplified IITBHU lowered arsenic levels up 95%. reductase expression present involved conversion into more soluble (III). isolate short rods and it ranged 500 1900 nm length 352.3 519.8 width. differences pre post exposed Amide I area were linked peptide bonds, C–H C=O stretchings. These variations reflected changes structure makeup proteins, lipids carbohydrates cell wall. exhibited rougher surfaces 156.120 109.609 nm, respectively than control (103.112 nm). Peak-to-peak height measurements 940.66 for control, 1246.833 703.125 (V). considerably significant support remediation phenomena isolate.
