A method for long chain fatty acids (LCFA) extraction, identification and further quantification by gas chromatography was developed and its application to liquid and solid samples collected from anaerobic digesters was demonstrated. After validation, the usefulness of this method was demonstrated in a cow manure digester receiving pulses of an industrial effluent containing high lipid content....

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

Prospects for the development of hydrolysis production are determined by relevance industrial use plant biomass to replace declining reserves fossil organic raw materials and increasing demand ethanol, especially its as automobile fuel, protein-containing feed additives that compensate protein deficiency in production, other products. Based on review research results presented scientific litera...

In this study, Citrus sinensis (C. sinensis) solid waste was used to catalyze the conversion of free cyanide (F-CN) under alkaline conditions; conditions which represent most industrial wastewater containing F-CN. Acid hydrolysis of the solid waste increased the catalytic conversion of FCN by 3.86 compared to the unhydrolysed solid waste. The conversion of F-CN using unhydrolysed and hydrolysed...

Silica-bonded n-propyldiethylenetriamine sulfamic acid (SBPDSA) was found as an efficient solid acid for the synthesis of coumarins. Coumarin derivatives were obtained via the Pechmann condensation reaction of phenols and β-keto-esters at 80 oC under solvent-free conditions. Also, biscoumarins were obtained via the condensation of aldehydes and 4-hydroxycoumarin in water at reflux conditions. T...

ÐFerron reagent and FTIR spectroscopy were used for the identi®cation and characterization of the aluminum species formed during dephosphorization of simulated wastewater with and without organic matter. Evidence from FTIR spectroscopy showed the formation of aluminum hydroxyphosphate, hydroxy-Al±tannate and aluminum complexes containing both phosphorus and tannic acid. The surface reactivity o...

Porous polymeric solid acids bearing hydroxyl and sulfonic acid groups, synthesized from aromatic monomers via the Friedel-Crafts “knitting” polymerization, could efficiently hydrolyze cellulose. • Bifunctional porous were for hydrolyzing polymerization followed by sulfonation was used to synthesize acids. Hydroxyl groups as cellulose-binding sites enhanced catalytic performance of acid. struct...

abstract effect of different concentrations of salicylic acid on postharvest life of kiwifruit (actinidia deliciosa) cultivar hayward at 0 ±.5 °c and 90-95% rh was studied. fruits were treated with salicylic acid (0, 1 and 2 mmol/l-1) and stored at 0±.5°c for 16 weeks. fruit quality attributes assessment including firmness, total acidity, soluble solid content, ascorbic acid, antioxidant activi...

A hydrothermal pre-treatment has been developed to improve sewage sludge quality or produce low nitrogen biocrude via liquefaction (HTL) in a subsequent step. The mild (150 °C) step was performed with deionized water, sulfuric acid (0.5 M), citric M) solubilize containing compounds the aqueous supernatant. Downstream, residual solid material liquefied addition of sodium carbonate (350 °C). tran...
