“…The intermediates formed by the microbial degradation of lignin include vanillin (4-hydroxy-3-methoxybenzaldehyde), dicarboxylic acid, cis -muconic acid, and polyhydroxyalkanoates (PHAs). Therefore, vanillin is a high-value-added intermediate generated from the two approaches [ 33 ].…”

“…Tannins may not be fully explained by the archaeological context, but their presence con rms the use of plant-based materials. Lignin, detected with SR μ-FTIR, shows a potential correlation with other degradation products by enzymatic action 54 , identi ed through HRMS. These compounds, including pcoumaric, 4-hydroxyphenylacetic, gentisic, ferulic, and isoferulic acids, are also synthesized via the phenylpropanoid biosynthetic pathway in plants 55 .…”

This study presents a comprehensive multimodal analytical study of an Egyptian ritual Bes-vase, of the 2nd century BCE employing cutting-edge proteomics, metabolomics, genetics techniques, and synchrotron radiation-based Fourier Transformed Infrared microSpectroscopy (SR µ-FTIR) to characterize organic residues of its content. We successfully identified the presence of various nutraceutical, psychotropic, medicinal, and biological substances, shedding light on the diverse components of a liquid concoction used for ritual practices in Ptolemaic Egypt. Using LC-MS/MS with a new methodological approach, we identified key proteins and metabolites, enabling the identification of botanical sources, confirmed by genetic sequences. Our analyses revealed traces of Peganum harmala, Nimphaea nouchali var. caerulea, and a plant of the Cleome genus, all of which are traditionally proven to have psychotropic and medicinal properties. Additionally, the identification of human fluids suggests their direct involvement in these rituals. Furthermore, metabolomics and SR μ-FTIR analyses also revealed the presence of fermented fruit-based liquid and other ingredients such as honey or royal jelly. The identification of specific chemical compounds, such as alkaloids and flavonoids, provides insight into the psychoactive and therapeutic uses of these in ancient ritual practices. This multidisciplinary study highlights the complexity of ancient cultures and their interactions with psychoactive, medicinal, and nutraceutical substances. These findings contribute to our understanding of ancient belief systems, cultural practices, and the utilization of natural resources, ultimately enhancing our knowledge of past societies and their connection to the natural world.

“…The gradual increase in the relative content of lignin can be attributed to its intricate chemical structures and high degree of polymerization, which render it less susceptible to microbial and moisture degradation. 29 Figure 1 illustrates the macroscopic and surface morphological changes of straw fibers during the biological pretreatment process. As the pretreatment time extended, there was a gradual darkening in the apparent color of straw fibers (Figure 1a), primarily attributed to the gradual exposure of lignin.…”

Biodegradability of fiber-based bio-pot is not only determined by the properties of individual fiber and resin components but also significantly influenced by the behavior of the fiber−resin interphase. Herein, we fabricated bio-pots by utilizing bio-pretreated straw fiber and keratin-modified resin and clarified the interphase degradation mechanism by fiber and composite pot characterization, respectively. The bio-pots exhibited enhanced mechanical properties and hydrophobicity due to improved interfacial adhesion. However, the pretreatment reduced the hemicellulose content in the fibers from 30.06% to 15.84%, resulting in a decrease in the biodegradation rate of bio-pot. Scanning electron microscope and nano-indentation results elucidated that the reinforcing effect of resin on pretreated fibers diminished the interphase's susceptibility to moisture and soil microbials, leading to decreased mechanical loss during natural degradation (e.g., from degradation rate 44.0% for blank samples to 37.4% for 10 day pretreated fiber-based pots at the modulus). The significance of the results may improve bio-pot environmental sustainability and predict its life cycle through interphase degradation. Additionally, the results demonstrate the great future potential on recycling of waste natural fiber and development of composite bio-pot with controllable biodegradability.
