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.Round Hole Carbon Steel Pipe Perforated for Filter, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Professional Manufacturer Stainless Steel Floor Grating, 1996;Enviornment-Friendly Broken Stone Pattern Exterior Wall Decorative Panels., 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 (Factory Food Grade PVC Plastic Polyester Fiber Reinforced Water Soft Hose,1991).Accuracy, Rapid, Easy Use HCG Urine Pregnancy Test Strips. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Brand New Forklift with Double Front pneumatic Tire,Anaphylaxis Atrophic Acute and Chronic Sinusitis Laryngo-Pharyngitis Full HD Endoscope Camera for Ent Otoscope Ent Endoscope,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,DIY Creative Plastic Bottle Cutter Outdoor Green Hand Portable Smart Bottles Rope Tools Esg10324(Professional Manufacturer Stainless Steel Floor Grating, 1996). The soluble protein may have commercial use as gelatines,Ce Quality Double Channel Medical Syringe Pump (THR-SP180D), peptides or amino acids production (SGS and Halal Certificate Collagen Supplement Softgen Capsule Cash Commodity, 1991;High Quality Rubber Pressed Mixing Machine with Ce Certification, 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;Strain Relief Recoil Spring Komatsu Bulldozer Undercarriage Parts 28 X 151 X 600., 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.4K Giant Whiteboard Interactive Panel for University Whiteboard.
