“…These radicals are characteristic of disordered regions of MWCNTs, which conforms the nucleation sites for hydrogen atoms. Other signals attributed to stretch vibrations of C-H at ~2,200 cm −1 and C–H X groups of the disordered sp3 region and vibration rings at 600 cm −1 were characteristics of MWCNTs ( Al-Rekaby, 2018 ; Lehman et al, 2011 ). Conversely, we observed that the FTIR spectra of the culture residue from P. ostreatus cultivated with MWCNTs + lignin indicated the absence of the characteristic bands of the MWCNTs, also a characteristic peak of the COOH functional radicals was identified at ~1,700 cm −1 ( Fig.…”

Multi-walled carbon nanotubes (MWCNTs) are of multidisciplinary scientific interest due to their exceptional physicochemical properties and a broad range of applications. However, they are considered potentially toxic nanoparticles when they accumulate in the environment. Given their ability to oxidize resistant polymers, mycorremediation with lignocellulolytic fungi are suggested as biological alternatives to the mineralization of MWCNTs. Hence, this study involves the ability of two fungi specie to MWCNTs biotransformation by laccase and peroxidases induction and evaluation in vivo of its toxicity using Caenorhabditis elegans worms as a model. Results showed that the fungi Penicillium chrysogenum and Pleurotus ostreatus were capable to grow on media with MWCNTs supplemented with glucose or lignin. Activities of lignin-peroxidase, manganese-peroxidase, and laccase in cultures of both fungi were induced by MWCNTs. Raman, FTIR spectroscopy, HR-TEM, and TGA analyses of the residue from the cultures of both fungi revealed structural modifications on the surface of MWCNTs and its amount diminished, correlating the MWCNTs structural modifications with the laccase-peroxidase activities in the fungal cultures. Results indicate that the degree of toxicity of MWCNTs on the C. elegans model was enhanced by the structure modification associated with the fungal ligninolytic activity. The toxic effect of MWCNTs on the in vivo model of worms reveals the increment of reactive oxygen species as a mechanism of toxicity. Findings indicate that the MWCNTs can be subject in nature to biotransformation processes such as the fungal metabolism, which contribute to modify their toxicity properties on susceptible organisms and contributing to environmental elimination.

“…, Rekaby -Layth Sareea Al 4 detention and the relative area of the compounds, The obvious differences showed the effect of treatments with nano fertilizers and bio fertilizers on the content of the plant root. The goldenrods was represented by an increase in the proportions of some compounds over others, the emergence of new compounds, and the disappearance of others, according to the statistical analysis data presented in Table (1 The results of the statistical analysis presented in Table (2) for the compound Stigmasta-7,16-dien-3-ol, (3.beta)) were found in the root of the Goldenrods plant for the compounds that were detected in the data of the GC Mas device, which was the retention time (34.151), as the addition of the nano fertilizer at a concentration of 1 gm/ L showed an increase in the percentage of the compound, but it was not significant, as it was recorded at 6.82, and when the concentration of the nano fertilizer was increased to 2 gm/ L, the percentage of the compound decreased until it reached a ratio of 4.23 compared to the comparison plants. It scored 6.05, as for the use of bio fertilizer, it led to an increase in the compound percentage, but it was not significant, as it achieved a percentage of 6.00 compared to the comparison plants, which recorded 5.40.…”

This experiment was done to find out to assess the effect of three concentration of Nano fertilizer 0, 1 and 2 gm./L , and the bio fertilizer at two levels 0 and 20 gm./L and their interactions on production of active ingredient of Solidago canadensis L. (goldenrods) , that planted in plastic pots. the active compounds in roots were measured After finishing experiment by Gas Chromatography-Mass Spectrometry (GC-MS) ( Manufacturer: Agilent 5977 A MSD , USA) The show results that the experimental treatment effect a significant increase in all measured parameters. Chemical description of extract has been carried out using gas chromatography and mass spectrometry (GC-MS). forty identified components in S. canadensis of total compounds in the fundamental compounds were identified as medical activity. The efficacy test included the effect of the alcohol extracts of the plant by inhibiting the growth of bacterial genera by the method of diffusion by drilling on the Mueller-Hunton medium. The laboratory experiment was carried out using Complete Randomized Design (CRD) with two factors (6 × 2) and three replicates for each treatment, the first factor, the type of extract for each plant treatment, and the second, the concentrations of the extract (100 and 200 mg / ml). The averages were compared when the differences were Significance using modified significance test RLSD with a significance level of 0.01. The results show : The higher level increased of concentration Benzofuran after treatment by 2 gm./L Nano fertilizer without Bio fertilizer, The higher level increased of concentration Stigmasta-7,16-dien-3-ol, (3.beta).after treatment by treatment 1 gm./L Nano fertilizer and 20 gm. /L Bio fertilizer , The higher level increased of concentration Phthalic acid after treatment by treatment 1 gm./L Nano fertilizer and 20 gm. /L Bio fertilizer , The higher inhibition diameter of Staphylococcus aureus after treatment by treatment 1 gm./L Nano fertilizer and 20 gm. /L Bio fertilizer , Which is Achieve 15.00 mm and The higher inhibition diameter of Pseudomonas aeruginosa after treatment by treatment 2 gm./L Nano fertilizer and 20 gm. /L Bio fertilizer , Which is Achieve 15.00 mm.

Roselle (Hibiscus sabdariffa L.) is a comestible plant known for its fleshy red calyces that are used in making a wide range of foods such as wine, juice, jam, syrup, pudding, cakes, ice cream, and herbal tea. The anti- bacterial, diuretic, antioxidant, and anti-mutagenic effects of the roselle calyces are also well known. It is high in vitamins, minerals and bioactive substances such as organic acids, phytosterols, and polyphenols, and because of its extensive phar-macological potential, it has long been used as folk medicine to treat common cold. Gas chromatography-mass spectroscopy (GC-MS) is the best technique to identify the compounds present in the sample by mass spectra data obtained from purely available standards injected under the same conditions. In this study, the GC-MS technique was used to validate the pharmacological potential of Hibiscus sabdariffa by identifying the chemicals found in its calyces. The maximum cyanidin-3-glucoside was found to be the highest in PKM (Periyakulam) HS 04 1784.65 mg/100 g in cyanidin-3-glucoside equivalents, total flavonoid content (28.01 mg QE/g), and DPPH (2-diphenyl-1-picrylhydrazyl) activity % (93.17), and in PKM HS 02 total phenolic content (1.29 GA mg/g). The extract was prepared by soaking a dry calyx powder sample in methanol overnight and the ethanolic extract was then analyzed using GC-MS. Flavonoids, tannins, phenols, saponins, alkaloids, glycosides, terpenoids, and steroids were found in the ethanolic extract of Hibiscus sabdariffa calyces. The existence of 26 bioactive chemicals was discovered by GC-MS analysis, including phthalic acid, astaxanthin, lutein, lycoxanthin, 3-Pyridinecarboxylic acid, rhodoxanthin, molybdenum, and hexadecenoic acid. The presence of some of these bioactive chemicals has been used to support scientific evidence for the plant’s anti-aging, anti-oxidant, anti-hypertensive, and anti-inflammatory capabilities, which constitute valuable preliminary information in pharma industries.
