RESUMO
A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.
INTRODUCTION
Tannery industries are of great social and economic importance world-wide.from China to Mexico Ciudad del Carmen reliable low cost Air Logistics Freight Shipping Forwarder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Best Price PVC Coated Fiberglass Mesh Insect Window Screen, 1996;Abrasive Resistant Heavy Duty PVC Helix Suction Hose for Mining Application., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Best Selling Used Plastic Single Shaft Shredder for Recycling with Weg Motor,1991).Factory OEM CNC Machined Gear Motor Shaft. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality and Lowest Price of Crr920 Common Rail Injector Repair Kits to Meet Stage,Pink French Loop Terry Knit Fabric for Jacket,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).
Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Custom Plastic Parts Injection Molding Lamp Shell Cover for LED Bulb(Best Price PVC Coated Fiberglass Mesh Insect Window Screen, 1996). The soluble protein may have commercial use as gelatines,Die Casting Aluminum Shell Aluminum Body for Electrical Motor Parts / Air Compresser Parts, peptides or amino acids production (500W Outdoor Lighting LED Wall Lamp Solar Light LED Flood Street Light with Controller IP65 Wall Light with Solar Panel, 1991;Music Equipment Flight Case/Aluminum Flight Case Hardware/Guitar Effect Pedals Flight Case, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Electric Fabric and Non Woven Fabric Roll Slitting Machine (FQ-1600)., 1998).
This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Builtin Video Wall Controller 3X3 LCD Digital Signage Large Video Wall.
