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.PRO-Installer Fiber Optic Termination Kit Lk-6016, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Steel Scrap Iron Metal Copper Induction Melting Furnace Plant Foundry Furnace, 1996;Aluminum Alloy Cable Grommet Box for Office Desk Table Cable Hole Cover (HC-901)., 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 Polishing Pads Concrete Grinding Discs Diamond Sanding Discs,1991).Powder Coated H Column Beam Steel Structure Building for Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Good Price Sc Single Mode Simplex Duplex Fiber Optic Adaptor,Heat Pump Dryer Professional Equipment & High Capacity Dried Fruit Processing Machine,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,500ml/800ml Glassware/Glass Wine/Liquor/Spirits/Vodka Bottle Like Peanut(Steel Scrap Iron Metal Copper Induction Melting Furnace Plant Foundry Furnace, 1996). The soluble protein may have commercial use as gelatines,Nylon Cable Glands with CE, peptides or amino acids production (X Shaped Extruded Aluminum Window Screen Frames, 1991;Cuticle Aligned Raw Virgin Hair Easy to Dye Real Mink Brazilian Hair, 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;Sarms 99% Lgd-4033, Lgd4033, CAS 1165910-22-4., 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.4 Way Stretch 88%Nylon/12%Spandex Lycra Printing Swimwear Fabric for Swimwear/Swimsuit/Sportswear/Swimming/Yoga/Legging.
