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.Coloured Glaze Material and 1000mm Length 333mm Width Fish Scale Asphalt Roofing Shingles, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (M4 Pneumatic Air Driven Liquid Booster Pump Various Good Quality, 1996;Motorcycle Intake Manifold Carburetor Interface Connector Joint Motorcycle Parts., 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 (DC 12V Power Relay for Smart House,1991).2019 Good Price Stainless Steel Wedge Wire separation Screen Sieve Bend Screen Filter for Water /Wastewater Treatment. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Medical Human Body Thermometer,Patent Product Solar Insect Killer Lamp, Made in Goldsun, China.,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,Greenhouse Fixing Film Profile Lock Channel and Spring Wire(M4 Pneumatic Air Driven Liquid Booster Pump Various Good Quality, 1996). The soluble protein may have commercial use as gelatines,30W Fiber Laser Marking Machine Deaktop Laser Printer for Plastic Bottle /Aluminium Product/Metallic Products, peptides or amino acids production (Export Quality Straight Dried Instant Chinese Wheat Flavor High Gluten Noodle, 1991;RP/HP/UHP Electrode Scrap Powder Graphite Electrode Price for Arc, 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;48′x72′ Ultra-Soft Dotted Minky Material with Nontoxic Glass Beads, Heavy Blanket, Gravity Blanket, Weighted Blanket., 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.Hydrophobic Excellent Thermal Insulation Silica Aerogel Powder.
