Bagasse and wheat bran are agrowaste and cause different environmental problems. These compounds contain highly valuable compounds that can be recycled by microorganisms. This work was carried out to evaluate the effect of fermentation by Bacillus subtilis on biological activity and chemical components of bagasse and wheat bran. The results demonstrated the antimicrobial activity of fermented wheat bran and bagasse against eight selected microbial pathogens exhibited high activity of fermented wheat bran and mix, fermented bagasse showed less antimicrobial activity. Fermented wheat bran and bagasse samples had the highest antioxidant activity values (16.45 and 14.94 %) in comparison with the unfermented samples (6.20 and 3.97 %) respectively. Concentration of protein, ash, oil, and carbohydrates in fermented wheat bran were 5.34 %, 7.30%, 2.36% and 10.6%, whereas in bagasse they were 2.45%, 1.68%, 1.51% and 3.25 respectively. The moisture contents in bagasse 73.1% were more than in wheat bran 63.88%.

The present investigation was carried out to prepare gluten free biscuits with high quality for celiac patients. The chemical analysis as minerals, amino acids of raw materials was estimated. Also, chemical composition for gluten free biscuits blends was determined and results showed that protein, ether extract and fibre contents were higher in all samples prepared using cassava flour, quinoa flour and sweet potato flour than those samples prepared using cassava flour. Volume, length, spread ratio and width of gluten free biscuit blends B2, B3, B4 and B5 decreased but thickness and bulk density increased compared to cassava flour biscuits B1. All sensory characteristics of free gluten biscuits samples B2, B3, B4 and B5 prepared using cassava flour, quinoa flour, and sweet potato flour were somewhat higher than biscuits prepared from cassava flour B1. Finally, blends B2 and B5 had higher scores in sensorial evaluation, chemical analysis, and physical attributes.

The synthesis, anticancer and antimicrobial properties of novel N-aryl-2-(5-aryltetrazol-2-yl)acetamides were discussed. Novel N-aryl-2H-tetrazoles were synthesized and modified in order to obtain the compounds with a satisfactory pharmacological profile. The structures of target substances were confirmed by using ¹H spectroscopy, mass spectrometry and elemental analysis. Anticancer activity screening was carried out within the framework of Developmental Therapeutic Program of the National Cancer Institute's (DTP, NCI, Bethesda, Maryland, USA). The compounds with significant levels of anticancer activities have been found that can be used for further optimization. The antimicrobial activity of the synthesized substances was evaluated by the value of the MIC and minimum fungicidal and bactericidal concentration. The findings exhibited that the compounds possessed moderate antimicrobial potential.

In developing countries, it still suffers from endless problems regarding wastewater treatment and the problem of choosing the appropriate treatment system due to lack of proper technology and weak economy. This study highlights the maturity oxidation pond (stabilization) of small communities as an effective, low-cost and simple post-treatment technique for treating wastewater before discharging into an aquatic ecosystem. The Rashid plant was cited as a treatment plant in the city of Rashid-ElBeheira Governorate - Egypt as a model plant for applying this technology in treatment of wastewater. This work also includes the studying of the relationship between climatic conditions, physicochemical parameters and biomass of microorganisms to evaluate the efficiency of its performance.

A series of isoxazole derivatives, 3-aryl-5-[5-(4-nitrophenyl)-2-furyl]-2,3-dihydroisoxazoles (5a-j) were synthesized by cyclocondensation reaction between 1-aryl-3-[5-(4-nitrophenyl)-2-furyl]prop-2-en-1-ones (4a-j) and hydroxylamine hydrochloride in presence of sodium acetate in glacial acetic acid at reflux temperature. Formerly, compounds (4a-j) were synthesized by the condensation of 5-(4-nitrophenyl) furan-2-carbaldehyde (3) with various aromatic ketones by using alkali as catalyst. The structures of the synthesized various isoxazole have been characterized by using elemental analysis, Infrared,¹H-NMR spectroscopy and further supported by Mass spectroscopy. All the products have been screened for their in-vitro biological assay like antibacterial activity towards Gram-positive and Gram-negative bacterial strains and antifungal activity towards Aspergillus niger at a concentration of 40 µg/ml. It was exposed that the compounds 5a, 5c, 5e, 5f, and 5i showed inspiring antibacterial and antifungal activity compared to the used reference standard.

Spodopetra Frugiperda is a highly polyphagous migratory lepidopteran pest species. It causes infestation in crops leading to severe crop losses. Being a new invasive parasite, its susceptibility to insecticides needs to be explored and therefore, there is an urgent need to develop the potent insecticides for the effective control of this insect pest. This is the first report on toxic effects produced by the prepared chalcone and hydrazone analogs, followed by structure relationships. Five compounds of chalcone and hydrazone derivatives have been synthesized in pure state as reported procedures, and their toxicity as potential insecticidal agent against Spodopetra Frugiperda was screened. Their characterizations by using spectroscopic analyses were performed. The toxicity data exhibited that compound 5 is more toxic about 2-fold than other synthesized compounds, the other screened compounds showed weak to strong toxicological activity against Spodopetra Frugiperda (lepidoptera: Noctuidae).

This research was carried out in order to evaluate the benefits of date seed powder (DSP) by adding it to bakery products to enhance the nutritional value of these products and maximize the economic value of these wastes. Thus, the contents of the (DSP) were determined from the chemical composition, mineral elements, amino acids, fatty acids, phenols and flavonoids, afterthought DSP were added to the toast bread and crackers with a ratio of 5, 10 and 15 % as substitute of the wheat flour and then the organoleptic properties of these products were evaluated. The findings of these investigations revealed that the (DSP) contains important minerals, essential amino acids, unsaturated fatty acids and antioxidants, and all of these compounds have an effective effect on the health of the body. In addition, the Sensorial evaluation of toast bread and crackers were shown to be acceptable by the judges, and thus the possibility of adding DSP to bakery products.

A series of furan derivatives tebufenozide analogues comprising five compounds (2, 3, 4, 5, and 6) have been designed and synthesized via reaction of N'-phenylfuran-2-carbohydrazide (1) with different acid chlorides. The structures of the synthesized compounds were identified by elemental analyses and spectroscopic data. The analogues compounds have the active center of tebufenozide (mimic) with change of tertiary butylhydrazine by phenylhydrazine. Studying the effect of this change on the toxicological activity against Spodoptera littoralis larvae was performed for three compounds of the synthesized ones. Toxicological activity data showed that compound (3) is more active than compounds (2) and (5)

The FTIR and Raman spectra of dopamine were also recorded in the spectral region 20 - 4000 cm^-1 and 400 - 4000 cm^-1 respectively. The optimized molecular geometry and fundamental vibration frequencies are interpreted using structural optimizations based on the DFT method. The B3LYP / 6-311G (d, p) was used to determine the calculations of the chemical descriptor. The dopamine (DA) molecule can acquire a maximum charge of 0.513 eV from its environment. To understand the molecular interactions of Dopamine, the MEP is a crucial tool. Nonlinear optical descriptors (NLO) and the lengths, bond angles are also determined by DFT and MP2 methods. The DFT method was used to determine the chemical shifts of ¹H and ¹³C of the product. These constants have been calculated by employing the GIAO (Gauge-Including-Atomic-Orbit), CSGT (Continuous Set of Gauge Transformations) and IGAIM (Individual Gauges for Atoms In Molecules) methods at the B3LYP/6-311G (d, p). The comparison of the theoretical chemical shifts with the experimental ones shows that the CSGT method is the best.
