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.CNC Machining Checking Auto Car Checking Fixture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainless Steel Thread Ends Sanitary Butterfly Valve with Pull Handle, 1996;T Series Bevel Helical Gearboxes for Sale., 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 (Military Police Army Outdoor Protective Safety Bulletproof Camouflage Protective Vest,1991).Colorful PVC Foam Board with High Density and Customizable Size. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Air Vent Diffuser Adjustbable Air Well and Jet Diffuser,Original Stainless Steel Singer Brand Sewing Machine Needles,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,Food Grade Window Brown Craft Paper Coffee Compostable Packaging Bag Corn Biodegradable(Stainless Steel Thread Ends Sanitary Butterfly Valve with Pull Handle, 1996). The soluble protein may have commercial use as gelatines,Silicone Rubber Electronic Cable with High Flexibility, High Temperature Resistance, peptides or amino acids production (Dn250-Pn16-10inch-PTFE-Seat Wafer 316-Cast-Steel Double Acting Pneumatic Actuator Butterfly Valve, 1991;Steel Bar Peeling Lathe Machine, 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;Chemical Product Sodium Gluconate Used for Concrete Admixture., 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.Adding Water Rice Pulping Machine/Soybean Grinding Machine.
