Having high cytotoxicity cell line effect, Cinnamomum zeylanicum Blume essential oil offers a novel approach to the chemotherapy treatment. In order enhance its quantity/purity, experimental conditions produce should be more exploited. Steam distillation was used isolate oil, and conditions’ optimization carried out with surface-response methodology. The maximum amount (2.6 g/100 g d.b.) obtained under minimum condensation water flow (0.8 mL/min), sample size of 6.5 cm, saline solution...
Abstract This work deals with the optimization of culture conditions Bacillus invictae AH1 in order to increase production level proteolytic activity. Response‐surface methodology (RSM) was applied for most significant fermentation parameters (concentration wheat bran and K 2 HPO 4 /KH PO ) that were earlier identified by Plackett–Burman Design from seven possible factors. A central composite design used quadratic regression model producing active protease built. maximum activity reached...
Abstract A mesophilic bacterial culture, producing an extracellular alkaline lipase, was isolated from the gas‐washing wastewaters generated Sfax phosphate plant of Tunisian Chemical Group and identified as Staphylococcus capitis strain. The named S. lipase (SCL), has been purified to homogeneity culture medium. enzyme molecular weight around 45 kDa. Specific activities about 3,900 500 U/mg were measured using tributyrin olive oil emulsion substrates, respectively at 37°C pH 8.5....
Citrus fruits have been a valuable economic crop for thousands of years. Furthermore, citrus essential oils are significant in the perfume, food, and beverage sectors, as well aromatherapy medical medicines.The present study aims to evaluate phytochemical pharmacological potentials optimized sinensis 'Maltese half-blood' peels (CsEO) extraction yields using Response-Surface Methodology (RSM).There few investigations on oil.Citrus oil were performed by hydro-distillation (RSM). The analysed...
AbstractCancer is a significant global health issue with high recurrence rates despite extensive treatments. Hence, the search for new anticancer treatments of great importance. The purpose this study was to assess efficacy Citrus aurantium peels essential oil (CPEO) as potential anti-cancer treatment. Full Factorial Design 23 method employed optimize yield CPEO extraction and examine its antioxidant antiproliferative effects on HeLa MCF-7 cancer cell lines. GC-MS analysis revealed that...
Superoxide dismutase (SOD) is an enzyme that protects against oxidative stress from superoxide radicals in living cells. This was extracted sardinelle (Sardinella aurita) viscera, purified and characterized. The Cu/Zn-SOD to homogeneity by the three-step procedure consisting of heating at 65°C for 15 min, precipitation with ammonium sulphate (30–60%, w/v) Sephadex G-100 gel filtration a 7.17-fold increase specific activity. molecular weight native estimated be 40 kDa G-125 on HPLC column...
Abstract Background Salvia officinalis L. essential oil (SoEO) was mostly traditionally used to medicate various diseases as cancer. Then, the present work aims were: (1) model cytotoxicity effects of related human cancer cell lines kind (MCF-7 and HeLa) ; (2) optimize hydro-distillation extraction conditions SoEO; and, (3) determine in vitro scavenging capacity free radicals DPPH • , NO ABTS + ability reduce Fe 3+ . Methods The anti-proliferative abilities were evaluated by measuring...
