In this regard, it is imperative to both delineate their biodegradation capacity as well as select target antiseptics that can prevent this process, while remaining inert towards the painting materials. This study characterized the fungus &lt;em&gt;Iodophanus&lt;/em&gt; sp. STG-150, belonging to the &lt;em&gt;Pezizaceae&lt;/em&gt; family, which was isolated from bio-lesion sites of the 16th century painting “Deesis Tier of 13 Figures”—a unique habitat that has not been described before. To analyse their ability to degrade painting materials, cells of the STG-150 strain were inoculated onto crafted mock layers that were coloured with individual painting materials, including basis, adhesives, egg yolk emulsion and tempera paints, watercolour, and varnishes. STG-150 was able to actively grow on basis (pavoloka), adhesives (sturgeon glue and mordant), egg yolk emulsion, and ochre-pigment. Contrastingly, moderate growth was observed on watercolour black and varnishes (linseed oil, acrylic varnish). The addition of cobalt green, strontian yellow, cadmium red, and grey-green to the egg yolk resulted in significant antifungal resistance. Furthermore, the addition of zinc white and burnt sienna completely inhibited STG-150 growth. Using scanning electron microscopy (SEM), it was observed that STG-150 produced two morphological forms of mycelium on the egg yolk emulsion and ochre-pigment—vegetative and aerial with conidia. All other art materials revealed only vegetative mycelium. Fourier-transform infrared spectroscopy (FTIR) also detected areas of STG-150 growth at the periphery of the inoculation site that were invisible to the eye. Mineral pigments as an antiseptic cannot be used to protect paintings from biodegradation, as they introduce unwanted colouration and degrade the original colour. Consequently, a targeted selection of new generation antiseptics were developed for the protection of paintings against STG-150: (i) nucleoside derivatives: &lt;em&gt;N&lt;sup&gt;4&lt;/sup&gt;&lt;/em&gt;-dodecyl-5-methyl-2′-deoxycytidine (Ala 54), &lt;em&gt;N&lt;sup&gt;4&lt;/sup&gt;&lt;/em&gt;-dodecyl-5-methylcytidine (Ala 106), 3′-amino-&lt;em&gt;N&lt;sup&gt;4&lt;/sup&gt;&lt;/em&gt;-dodecyl-5-methyl-2′,3′-dideoxycytidine (SOV4); (ii) sulphur-containing heterocyclic compounds: 3,5-dinitropyridin-2-yl thiocyanate – (М1), 4-nitro-2,1,3-benzothiadiazol-5-yl thiocyanate (M2), 3-cyano-5-nitropyridin-2-yl thiomorpholine-4-carbodithioate (M3), and ethyl 1‑hydroxy-6-thioxo-1,6-dihydropyridine-3-carboxylate (М4); as well as (iii) &lt;em&gt;H&lt;/em&gt;-phosphinic amino acid analogues: 1-Aminoethyl-&lt;em&gt;H&lt;/em&gt;-phosphinic acid (Ala-pH), &lt;span&gt;l&lt;/span&gt;-amino-2-methylpropyl-&lt;em&gt;H&lt;/em&gt;-phosphinic acid (Val-pH), 1-amino-3-methylthiopropyl-&lt;em&gt;H&lt;/em&gt;-phosphinic acid (Met-pH), and &lt;span&gt;l&lt;/span&gt;-amino-2-carboxyethyl-&lt;em&gt;H&lt;/em&gt;-phosphinic acid (Asp-α-pH).

Property boundaries should encompass all elements that contribute to the OUV of the property and be sufficient to protect the OUV from any natural or anthropogenic threats. Climate change-related hazards are impacting WH properties at multiple scales. In many cases, especially for slow onset hazards, existing boundaries are not sufficient to monitor and respond to change. In these cases, it can help to explore the wider landscape context. This paper considers the utility of standardised remote sensing land use and land cover (LULC) data to understand the high-level environmental classifications within and surrounding cultural and mixed WH properties. Of 11 LULC classes within the analysed dataset, 10 were present in at least one of the 49 properties in the Indian Subcontinent recognised for their cultural heritage, with the most common being Tree cover (≥5% of the area of 40 properties and/or their surrounds). Protection of cultural properties from climate-based impacts can benefit from LULC analysis by responding to known climate-related risks (e.g., flood, wildfire, etc.) on specific land cover classes. These risk profiles can be useful decision support tools for climate adaptation. The analysis is demonstrated for four case studies at three locations, using properties with a range of sizes and values. For example, trees in the broader landscape within and around Khangchendzonga National Park may encounter future impacts from temperature change (resulting in shifting biomes and changing phenology), precipitation changes (resulting in changes in rainfall and drought) and wind changes (resulting in storm damage). Each of those climate drivers increase the risk of wildfires. Additionally, LULC analysis provides valuable information on a property’s environmental context when inscribed boundaries are unknown. This study demonstrates that a systematic and reliable analysis of LULC data can provide a way to consider the broader environmental context of WH properties, complementing property values described in their Statements of OUV. However, the study also acknowledges key limitations to using LULC, including classification accuracy concerns and challenges with validation across diverse site types.
