“…Glucosidase is a very common enzyme found in soils, which is used as a biochemical indicator to measure processes of degradation and stabilisation of OM [45] as it is involved in the carbon cycle [39]. In this context, it is necessary to know the activity of this enzyme to determine the stability of the substrate since it is proven that β-GLU hydrolyses cellulose into glucose [46].…”

Microorganisms are only effective when adequate conditions for their survival and development are provided. Among the factors that influence its effectiveness includes the type of soil or culture substrate, which works as an energy source reserve. Therefore, a tomato and a melon crop were established in different cycles to assess the effect of the physicochemical properties of organic substrates based on coconut fibre and vermicompost in three proportions, 0:100, 40:60 and 60:40 (% v:v), on the microbial activity in the rhizosphere when the bacteria Azotobacter vinelandii, Bacillus megaterium and Frateuria aurantia were applied. Concentrations of NO3−, H2PO4−, K+ and Ca2+ in the petiole cellular extract (PCE) were quantified at 60, 90 and 120 days after transplantation (DAT) for tomato and 45 and 65 DAT for melon. We analysed dehydrogenase activity (DHA), acid phosphatase activity (FTA) and β-glucosidase activity (β-GLU). In order to maintain optimal volumetric moisture for the survival of microorganisms, automatic control was used to manage the irrigation frequency between 22%–28%. The results showed that physicochemical substrate properties, by incorporating 40% vermicompost into the coconut fibre mixture, increased enzymatic activity. Plants that were inoculated with Azotobacter vinelandii and Frateuria aurantia showed an improvement in NO3− and K+ assimilation achieving highest yields.

“…ramotenellum respectively (Table 3), and autochthonous of Kinkarakawagami, are commonly found in several environmental matrices of Korea, China, Thailand, and Japan [37][38][39][40] , confirming the eastern provenance of these wallpapers. Besides, these microorganisms hold enzymatic assets (i.e., xylanases and laccases) that enable them to degrade and depolymerize (1) lignin and cellulose compounds 37,[40][41][42][43][44] , (2) lacquers [45][46][47] , and (3) organic pigments 46,48 .

“…produce extracellular xylanases 42,43,49 , which efficiently hydrolyse lignocellulosic material and the Indigo pigment 42,43 , a biotic aspect that supports their presence on INV_11_1, INV_11_4, INV_13_5, and INV_13_4 (Table 3). Laccases are instead Cu-polyphenol oxidases firstly identified in the exudates of the Japanese Rhus verniczfera plant 50 from which the Urushi lacquer is extracted 32 , yet also recognized as enzymatic catalyst of most fungal strains 47 . Since these enzymes are responsible for the degradation of phenol substrates 45,47 , the partial identification of vibrational modes typical of urushiol polymerization or Indigo ( Supplementary Tables 1-4) could be ascribed to the biotic deterioration of both Urushi lacquer and organic pigment, as Japanese lacquer IR contributions were found within sampling points where fungal strains were isolated (Tables 2, 3).…”

A combined physical–chemical and microbiological approach to unveil the fabrication, provenance, and state of conservation of the Kinkarakawa-gami art

Kinkarakawa-gami wallpapers are unique works of art produced in Japan between 1870 and 1905 and exported in European countries, although only few examples are nowadays present in Europe. So far, neither the wallpapers nor the composing materials have been characterised, limiting the effective conservation–restoration of these artefacts accounting also for the potential deteriogen effects of microorganisms populating them. In the present study, four Kinkarakawa-gami wallpapers were analysed combining physical–chemical and microbiological approaches to obtain information regarding the artefacts’ manufacture, composition, dating, and their microbial community. The validity of these methodologies was verified through a fine in blind statistical analysis, which allowed to identify trends and similarities within these important artefacts. The evidence gathered indicated that these wallpapers were generated between 1885 and 1889, during the so-called industrial production period. A wide range of organic (proteinaceous binders, natural waxes, pigments, and vegetable lacquers) and inorganic (tin foil and pigments) substances were used for the artefacts’ manufacture, contributing to their overall complexity, which also reflects on the identification of a heterogeneous microbiota, often found in Eastern environmental matrices. Nevertheless, whether microorganisms inhabiting these wallpapers determined a detrimental or protective effect is not fully elucidated yet, thus constituting an aspect worth to be explored to deepen the knowledge needed for the conservation of Kinkarakawa-gami over time.

“…Phosphorus is the crucial element in living organisms that involves many biologically important processes such as plant growth, energy storage, photosynthesis, cell regulation and signaling etc [1] . Phosphatase, a natural enzyme widely found in living systems, can remove phosphate groups from organic substrates into inorganic phosphates and hence play a significant role in the recycle of phosphorus [2] . The majority of the environmental phosphorus came from animal wastes before the 18 th century.…”

Electronic‐State Manipulation of Surface Titanium Activates Dephosphorylation Over TiO₂ Near Room Temperature

Dephosphorylation that removes a phosphate group from substrates is an important reaction for living organisms and environmental protection. Although CeO2 has been shown to catalyze this reaction, cerium is low in natural abundance and has a narrow global distribution (>90 % of these reserves are located within six countries). It is thus imperative to find another element/material with high worldwide abundance that can also efficiently extract the phosphate out of agricultural waste for phosphorus recycle. Using para‐nitrophenyl phosphate (p‐NPP) as a model compound, we demonstrate that TiO2 with a F‐modified (001) surface can activate p‐NPP dephosphorylation at temperatures as low as 40 °C. By probe‐assisted nuclear magnetic resonance (NMR), it was revealed that the strong electron‐withdrawing effect of fluorine makes Ti atoms (the active sites) on the (001) surface very acidic. The bidentate adsorption of p‐NPP on this surface further promotes its subsequent activation with a barrier ≈20 kJ mol−1 lower than that of the pristine (001) and (101) surfaces, allowing the activation of this reaction near room temperature (from >80 °C).
