[Ab] Resumo:This work was aimed to evaluate the feasibility of castor bean residue based activated carbons prepared through metals chloride activation. The activated carbons were characterized for textural properties and surface chemistry, and the adsorption data of rhodamine B were established to investigate the removal performance. Zinc chloride-activated carbon with specific surface area of 395 m /g displayed a higher adsorption capacity of 175 mg/g. Magnesium chloride and iron(III) chloride are less toxic and promising agents for composite chemical activation. The adsorption data obeyed Langmuir isotherm and pseudo-second-order kinetics model. The rate-limiting step in the adsorption of rhodamine B is film diffusion. The positive values of enthalpy and entropy indicate that the adsorption is endothermic and spontaneous at high temperature.

[Ti] Título:A graphene oxide-based strand displacement amplification platform for ricin detection using aptamer as recognition element.

[Ab] Resumo:The toxic plant protein ricin is a potential agent for criminal or bioterrorist attacks due to the wide availability and relative ease of preparation. Herein, we developed a novel strategy for the detection of ricin B-chain (RTB) based on isothermal strand-displacement polymerase reaction (ISDPR) by using aptamer as a recognition element and graphene oxide (GO) as a low background platform. In this method, ricin-binding aptamer (RBA) hybridized with a short blocker firstly, and then was immobilized on the surface of streptavidin-coated magnetic beads (MBs). The addition of RTB could release the blocker, which could hybridize with the dye-modified hairpin probe and trigger the ISDPR, resulting in high fluorescence intensity. In the absence of RTB, however, the fluorescence of the dye could be quenched strongly by GO, resulting in the extremely low background signal. Thus, RTB could be sensitively detected by the significantly increased fluorescence signal. The linear range of the current analytical system was from 0.75µg/mL to 100µg/mL and the limit of detection (3σ) was 0.6µg/mL. This method has been successfully utilized for the detection of both the RTB and the entire ricin toxin in real samples, and it could be generalized to any kind of target detection based on an appropriate aptamer.

[Ab] Resumo:An investigation was made into the feeding behavior of goats to evaluate the effects of a detoxified castor bean meal in the diet of goats. Thirty-six ½ crossbred Boer goats were used, with an average weight of 20 ± 3.2 kg. A completely randomized design was used with four treatments (diets with of 0, 100, 200, and 300 g detoxified castor bean meals/kg dry matter) and nine replicates. Castor bean meal was detoxified using calcium oxide. Diets were formulated to be isonitrogenous, and the forage:concentrate ratio was 50:50. The feeding behavior was observed on the 17th, 45th, and 70th days of the experiment. For the evaluation of feeding behavior (feeding, idle, and rumination times), the animals were observed in 5-min intervals for 24 h. The addition of detoxified castor bean meal did not change (P > 0.05) the evaluated behavioral variables. Linear reduction was observed (P < 0.05) in the efficiencies of feeding and rumination, expressed in g dry matter/h. The variables related to the time series discretization of the feeding behavior of goats did not change (P > 0.05) with the inclusion of detoxified castor bean meal. The inclusion of detoxified castor bean meal in growing goats' diets does not change the feeding, rumination, and idle times, however, decreases intake, feeding, and rumination efficiencies of dry matter.

[Ab] Resumo:Castor cake is the residue in castor oil production in which many active components exist and the major one among them is ricinine. In this study, optimization of extraction of ricinine from castor cake using ultrasonic-microwave synergistic extraction (UMSE) was investigated to obtain high yield and purity by Box-Behnken design (BBD) response surface design. The optimal conditions of extraction were: ultrasound power 342 W, extracting time 5 min, microwave power 395 W, and non-significant factor of liquid/solid ratio 1:10. The crude extraction was recrystallized from ethanol. As a result, the maximum yield of ricinine was approximately 67.52%. The purity of ricinine was 99.39% which was determined by high performance liquid chromatography (HPLC). Additionally, the structure of purified ricinine was identified by fourier transforms infrared (FTIR) and liquid chromatography-mass spectrometry (LC-MS). Scanning electron microscope (SEM) was used to characterize the prismatic crystals morphology of ricinine. Results demonstrated that the present method combined the advantages of ultrasonic extraction and microwave extraction, which is time-saving with high extraction yield. Our results offer a suitable method for large-scale isolation of ricinine.

[Ti] Título:Comparison of chelates for enhancing Ricinus communis L. phytoremediation of Cd and Pb contaminated soil.

[Ab] Resumo:We studied chelate effects on castor bean (Ricinus communis L.) growth. These effects included Cd and Pb accumulation in plant tissues and the chemical behavior of Cd and Pb in the plant rhizosphere and non-rhizosphere. Tests were conducted in a glasshouse using the rhizobag method. Two castor bean cultivars (Zibo-3 and Zibo-9) were grown in soil contaminated with 3.53mg/kg Cd and 274mg/kg Pb. The soil was treated with citric acid (CA), ethylenediamine disuccinic acid (EDDS) or ethylenediamine tetraacetic acid (EDTA) (5mmol/kg). EDDS-treated soil produced 28.8% and 59.4% greater biomass for Zibo-3 and Zibo-9 respectively. In contrast, CA and EDTA inhibited the growth of the two cultivars. Zibo-9 had greater tolerance than Zibo-3 to chelate toxicity. Based on Cd and Pb plant uptake, EDDS could substitute for EDTA for phytoremediation of Cd in soil. EDTA was the most effective of the three chelates for Pb phytoremediation but it is less suitable for field use due to toxicology environmental persistence. Acid extractable Cd and Pb in the rhizosphere or reducible Cd and Pb in the non-rhizosphere of soil were the main influences on Cd and Pb accumulation in castor bean.

[Ab] Resumo:BACKGROUND: Ricinus communis (Euphorbiaceae) has previously been reported to possess analgesic, antihistamine, antioxidant and anti-inflammatory activities. This study was designed for isolation, characterization and evaluation of antibacterial and anti-proliferative activities of R. communis seed protein. METHODS: The concentration and molecular weight of R. communis seed protein were estimated by SDS-PAGE and spectrophotometric analysis, respectively. Lectin activity was evaluated by hemagglutination assay on mice blood. In vitro susceptibility of four human pathogenic bacteria including Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes and Staphylococcus aureus was detected using disk diffusion assay, and minimum inhibitory concentration (MIC) value was determined using micro-dilution method. A total of twenty four Swiss albino mice containing Ehrlich's ascites carcinoma (EAC) cells were treated with the crude protein of R. communis at 50 and 100 µg/ml/d/mouse for 6 days. Growth inhibitory activity of R. communis seed protein on EAC cells was determined by haemocytometer counting using trypan blue dye and DAPI (4΄,6-diamidino-2-phenylindole) staining was used to assess apoptotic cells. RESULTS: The protein concentration of six R. communis (castor) varieties ranged between 21-35 mg/ml and molecular weight between 14-200 kDa. Castor protein agglutinated mice blood at 3.125 µg/wall. The seed protein shows considerable antimicrobial activity against E. coli, P. aeruginosa and S. aureus, exhibiting MIC values of 250, 125 and 62.5 µg/ml, respectively. Administration of seed protein led to 54 % growth inhibition of EAC cells at 100 µg/ml. DAPI staining indicates marked features of apoptosis including condensation of cytoplasm, nuclear fragmentation and aggregation of apoptotic bodies etc. CONCLUSION: Our study suggests that the lectin rich R. communis seed protein has strong antibacterial and anticancer activities.

[Ab] Resumo:Response of castor (Ricinus communis L.) to cadmium (Cd) was assessed by a seed-suspending seedbed approach. Length of total radicle was the most sensitive indicator of Cd tolerance among the tested germination and growth characters. The ED50 value for Cd was 11.87 mg L(-1), indicating high Cd tolerance in castor. A pot experiment was conducted by growing 46 varieties of castor under CK (without Cd) and Cd1 (10 mg kg(-1) of Cd) and Cd2 (50 mg kg(-1) of Cd) treatments to investigate genotype variations in growth response and Cd accumulation of castor under different Cd exposures. Castor possessed high Cd accumulation ability; average shoot and root Cd concentrations of the 46 tested varieties were 21.83 and 185.43 mg kg(-1), and 174.99 and 1181.96 mg kg(-1) under Cd1 and Cd2, respectively. Great variation in Cd accumulation was observed among varieties, and Cd concentration of castor was genotype dependent. The correlation between biomass and Cd accumulation was significantly positive, while no significant correlation was observed between Cd concentration and Cd accumulation, which indicated that biomass performance is the dominant factor in determining Cd accumulation ability.

[Ti] Título:Differential Contribution of Malic Enzymes during Soybean and Castor Seeds Maturation.

[Ab] Resumo:Malic enzymes (ME) catalyze the decarboxylation of malate generating pyruvate, CO2 and NADH or NADPH. In some organisms it has been established that ME is involved in lipids biosynthesis supplying carbon skeletons and reducing power. In this work we studied the MEs of soybean and castor, metabolically different oilseeds. The comparison of enzymatic activities, transcript profiles and organic acid contents suggest different metabolic strategies operating in soybean embryo and castor endosperm in order to generate precursors for lipid biosynthesis. In castor, the malate accumulation pattern agrees with a central role of this metabolite in the provision of carbon to plastids, where the biosynthesis of fatty acids occurs. In this regard, the genome of castor possesses a single gene encoding a putative plastidic NADP-ME, whose expression level is high when lipid deposition is active. On the other hand, NAD-ME showed an important contribution to the maturation of soybean embryos, perhaps driving the carbon relocation from mitochondria to plastids to support the fatty acids synthesis in the last stages of seed filling. These findings provide new insights into intermediary metabolism in oilseeds and provide new biotechnological targets to improve oil yields.

[Ab] Resumo:Keeping in view the versatile applications of castor oil in cosmetic, pharmaceutical and recently as renewable source, the present work is a step towards the commercialization of castor on large scale in Pakistan. The current study introduces a castor variety with high oil content. Initially seeds were physically examined for some physical parameters. Seed moisture, ash content and linear dimensions such as length, width and thickness were found to be 4.53%, 6.44%, 12.24 mm, 8.31 mm and 5.67 mm, respectively. For oil extraction, Soxhlet method was used which resulted in the high oil content 54.0%. For quality assessment of oil, physicochemical parameters were checked according to official standard AOCS methods and compared with ASTM specifications. The determined parameters were as follows; specific gravity 0.953 g/cm(-3), refractive index 1.431, viscosity 672.0 mPas.s, moisture content 0.32%, FFA 0.14%, IV 83.61 gI2/100 g, PV 2.25 meq/Kg and SV 186.0 mgKOH/g. Furthermore, fatty acid analysis of oil showed that, most abundant fatty acid was ricinoleic acid 94.59%, followed by palmitic 0.31%, linoleic 1.84%, oleic (n-9) 2.05%, oleic (n-10) 0.22%, stearic 0.45% and eicosenoic acid 0.53%. The detected fatty acids were compared with registered variety and varieties of other regions.
