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.High Pressure Low Volume 2900rpm electric Water Pump, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Design Fashion Jewelry 925 Sterling Silver Shell Pearl Clavicle Chain Necklace Bar Necklace, 1996;Haivol High Voltage 8.7/15kv Cold Shrinkable 1 Cores Outdoor Terminal Kit (Applicable of cable crosssection 240)., 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 (Boat Windlass Truck Auto Manual Lifting Hoist Tractortraction Hand Winch,1991).Multifunction Copper Busbar Processing for Aluminum Material. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Men Genuine Leather Sling Shoulder Satchel Messenger Bag,Electric DC 24V Geared Motor for Auto Doors,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,Disposable Medical Products Non Absorbable Sterile Surgical Suture Silk Braided(New Design Fashion Jewelry 925 Sterling Silver Shell Pearl Clavicle Chain Necklace Bar Necklace, 1996). The soluble protein may have commercial use as gelatines,RF Shielding MRI Door with Brass Frame for RF Cage, peptides or amino acids production (Geotextile Beg Used for Beach Restoration Geobag, 1991;Reusable Silicone Food Storage Bag, 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;Dental Emax Empress Crown From China Dental Lab., 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.Surface Cotton, Anti-Stick, High Temperature Resistance Conveyor Belt.
