“…(Family Myrtaceae) were extracted by the hydrodistillation method using the Clevenger apparatus at the Faculty of Agriculture (EL-Shatby), Alexandria University, Alexandria, Egypt, where approximately 150 g of small pieces of leaves were put in a 2 L flask containing 1500 mL of distilled water and then connected to a Clevenger unit and heated for 3 h under refluxing 50 , 63 . The EO was collected and dried over anhydrous sodium sulfate and the EO amount was calculated based on sample weight 10 as 2.44 mL/100 fresh leaves of E. camaldulensis . The collected EO was preserved at 4 °C in a refrigerator while being kept dry in an Eppendorf tube.…”

The most important uses of old fabrics include clothing, mummification, and bookbinding. However, because they are predominantly constructed of natural materials, they are particularly susceptible to physical and chemical deterioration brought on by fungi. The treatments that are typically used to preserve old textiles focus on the use of synthetic fungicides, which have the potential to be dangerous for both human health and the environment. Essential oils (EOs), which are safe for the environment and have no negative effects on human health, have been widely advocated as an alternative to conventional antifungals. Four natural fabrics—linen, cotton, wool, and silk—were utilized in the current work. The extracted EO from leaves of river red gum (Eucalyptus camaldulensis Dehnh.) were prepared at 125, 250, and 500 µL/L. Aspergillus flavus, Fusarium culmorum and Aspergillus niger were inoculated separately into the treated four fabrics with the EO at concentrations of 125, 250, and 500 µL/L or the main compounds (spathulenol and eucalyptol) at the concentrations of 6, 12, 25, and 50 µL/L and were then compared to the un-treated samples. GC–MS was used to analyze the EO chemical composition, while visual observations and scanning electron microscopic (SEM) were used to study the fungal growth inhibition. Spathulenol (26.56%), eucalyptol (14.91%), and p-cymene (12.40%) were the principal chemical components found in E. camaldulensis EO by GC–MS. Spathulenol molecule displayed the highest electrostatic potential (ESP) compared with the other primary compound, as calculated by quantum mechanics. In the untreated textile samples, SEM analysis revealed substantial proliferation of hyphae from A. flavus, F. culmorum, and A. niger. The fungal growth was completely inhibited at a concentration of 500 µL/L from the EO. Both eucalyptol and spathulenol completely inhibited the formation of the fungal spores at a concentration of 50 µL/L, although eucalyptol was more effective than spathulenol across the board for all four textiles. The results support E. camaldulensis EO functionalized textiles as an effective active antifungal agent.

The purpose of the current investigation was to ascertain the efficacy of cellulose and gellan gum in removing pomegranate stains and dirt from a historic printed manuscript from the year 1888 AD. To confirm the efficacy of these compresses before and after treatment, as well as after exposing treated samples to artificial aging, numerous studies including a digital microscope, scanning electron microscope (SEM), fourier transform infrared (FTIR), color change (ΔE), and pH were carried out. After cleaning and aging, promising results were obtained. p-Hydroxy benzoic acid, gallic acid, salicylic acid, benzoic acid, quercetin, catechol, and rutin were the most prevalent phytochemicals in the pomegranate stain, which was analyzed using high-performance liquid chromatography (HPLC). The digital microscope and scanning microscope demonstrated that the gellan gum compress was successful in removing stains but severely weakened the paper, resulting in a clear cut of the fibers and substantially removing the inks. In contrast, the cellulose compress effectively removed stains without harming the paper fibers. Both compresses revealed a substantial rise in ΔE in the treated sample. These alterations were connected to a rise in the paper samples' Lightness (L), which was measured after surface debris was removed. As groups remained unaffected after the cleaning procedure, infrared spectrum analysis proved that the chemical structure of the paper had not been altered. However, after cleaning, both compresses, particularly gellan gum, showed an increase in the intensity of peaks at 3400 cm−1 (OH stretching). Additionally, a significant change was seen following treatment, with pH values rising. Gellan gum and cellulose compresses were shown to be quite good at removing acidity, and since pH levels rose after treatment, this suggests that the stain was cleaned up and removed. Based on these findings, we suggest cleaning cellulosic supports with a cellulose compress.
