The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Alumina/silica supported K2CO3 as a catalyst for biodiesel synthesis from sunflower oil
(Elsevier Sci Ltd, Oxford, 2009)
The new type of catalyst for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as active component on alumina/silica support was synthesized using sol-gel method. Corresponding catalyst (xerogel) was prepared ...
Enzymatic conversion of sunflower oil to biodiesel in a solvent-free system: Process optimization and the immobilized system stability
(Elsevier Sci Ltd, Oxford, 2009)
The feasibility of using the commercial immobilized lipase from Candida antarctica (Novozyme 435) to synthesize biodiesel from sunflower oil in a solvent-free system has been proved. Using methanol as an acyl acceptor and ...
Production of lipase and protease from an indigenous Pseudomonas aeruginosa strain and their evaluation as detergent additives: Compatibility study with detergent ingredients and washing performance
(Elsevier Sci Ltd, Oxford, 2011)
An indigenous Pseudomonas aeruginosa strain has been studied for lipase and protease activities for their potential application in detergents. Produced enzymes were investigated in order to assess their compatibility with ...
Biodiesel synthesis at high pressure and temperature: Analysis of energy consumption on industrial scale
(Elsevier Sci Ltd, Oxford, 2009)
Analysis of several different schemes for industrial FAME production at higher pressure and temperature (catalytic or non-catalytic synthesis) was realized with the aim to find the best route to reduce the energy consumption ...
One-step, inexpensive high yield strategy for Candida antarctica lipase A isolation using hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2012)
Lipase A from Candida antarctica (CAL A) was purified to apparent homogeneity in a single step using hydroxyapatite (HAP) chromatography. CAL A bound to HAP was eluted with 10 mM Na-phosphate buffer, pH 7.0 containing 0.5% ...
Quality of chemically modified hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
Hemp fibers are very interesting natural material for textile and technical applications now. Applying hemp fibers to the apparel sector requires improved quality fibers. In this paper, hemp fibers were modified with sodium ...
Lactic acid production on liquid distillery stillage by Lactobacillus rhamnosus immobilized onto zeolite
(Elsevier Sci Ltd, Oxford, 2013)
In this study, lactic acid and biomass production on liquid distillery stillage from bioethanol production with Lactobacillus rhamnosus ATCC 7469 was studied. The cells were immobilized onto zeolite, a microporous ...
Production of enzymes by a newly isolated Bacillus sp TMF-1 in solid state fermentation on agricultural by-products: The evaluation of substrate pretreatment methods
(Elsevier Sci Ltd, Oxford, 2017)
Study on potential of different agro-industrial waste residues for supporting the growth of newly isolated Bacillus sp. TMF-1 strain under solid-state fermentation (SSF) was conducted aiming to produce several industrially ...
The effect of agitation intensity on alkali-catalyzed methanolysis of sunflower oil
(Elsevier, 2007)
The sunflower oil methanolysis was studied in a stirred reactor at different agitation speeds. The measurements of drop size, drop size distribution and the conversion degree demonstrate the effects of the agitation speed ...
