The interactions between collagen fibrils in many echinoderm connective tissues are rapidly altered by the secretions of resident neurosecretory cells. Recent evidence has suggested that a secreted protein is responsible for the interactions that lead to an increase in tissue stiffness (Trotter and Koob, 1995). Structurally intact collagen fibrils have been(More)
A comprehensive study of critical parameters in the pig pancreatic lipase (PPL) catalysed transesterification of sunflower oil to novel biofuels integrating glycerol into their composition is reported. The influence of oil/alcohol ratio, temperature, quantity of enzyme and water added and pH have been investigated. The enzymatic activity of PPL was found to(More)
Metal nanoparticles have attracted much attention over the last decade owing to their unique properties as compared to their bulk metal equivalents, including a large surface-to-volume ratio and tunable shapes. To control the properties of nanoparticles with particular respect to shape, size and dispersity is imperative, as these will determine the activity(More)
A preparative-scale enantioselective hydrolysis of racemic methyl esters of several N-protected amino acid has been carried out by using crude porcine pancreatic lipase (Triacylglycerol lipase, EC 3.1.1.3) PPL as a hydrolytic enzyme. In all cases 50% of the racemic methyl ester was hydrolysed to the N-protected L-amino acid with high yield and high optical(More)
By using 1,3-specific Pig Pancreatic lipase (EC 3.1.1.3 or PPL), covalently immobilized on AlPO(4)/Sepiolite support as biocatalyst, a new second-generation biodiesel was obtained in the transesterification reaction of sunflower oil with ethanol and other alcohols of low molecular weight. The resulting biofuel is composed of fatty acid ethyl esters and(More)
By using pig pancreatic lipase (EC 3.1.1.3 or PPL) as a biocatalyst, covalently immobilized on amorphous AlPO4 support, a new second generation biodiesel was obtained in the transesterification reaction of sunflower oil with ethanol. The resulting biofuel is composed of fatty acid ethyl esters and monoglycerides (FAEE/MG) blended in a 2:1 molar ratio. This(More)
The obtaining of Ecodiesel, a biofuel applicable to diesel engines which keeps the glycerin as monoglyceride (MG), was achieved through a selective ethanolysis process of sunflower oil, by application of Lipozyme RM IM, a Rhizomucor miehei lipase immobilized on macroporous anion exchange resins. This biocatalyst that was already described in the synthesis(More)
A new biofuel similar to biodiesel was obtained in the 1,3-selective transesterification reaction of sunflower oil with ethanol using as biocatalyst a Rhizopus oryzae lipase (ROL) immobilized on Sepiolite, an inorganic support. The studied lipase was a low cost powdered enzyme preparation, Biolipase-R, from Biocon-Spain, a multipurpose additive used in food(More)
A new biodiesel-like biofuel is obtained by the enzymatic ethanolysis reaction of sunflower oil with ethanol, in free solvent media, by using BIOLIPASE-R, a multipurpose alimentary additive from Biocon-Spain that is a low cost lipase from a strain of Rhizopus oryzae. This biofuel is composed by two parts of fatty acid ethyl esters (FAEE) and one of(More)
The effectiveness of conservation interventions for maximizing biodiversity benefits from agri-environment schemes (AESs) is expected to depend on the quantity of seminatural habitats in the surrounding landscape. To verify this hypothesis, we developed a hierarchical sampling design to assess the effects of field boundary type and cover of seminatural(More)
