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.Fudan Compatible Card 1k RFID Card 13.56MHz, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Happy Cat Tree Condo Pet Scratcher Tower Small Black Sisal Scratch Post, 1996;Biodegradable Food Packaging Take out Food Boxes., 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 (Wholesaler 4.3 Inch Mini Tablet PC Industrial Panel PC All-in-One PC Computer,1991).Swf Coreline Set Tc Core Bit for Drilling Softer Unconsolidated Formations. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,AC4 Grade Home and Commercial Use Wooden HDF Laminate Flooring,20 Ton Small Vertical Plastic Injection Molding 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,White Hand Carved Angel Sculpture, Marble Child Statue for Garden(Happy Cat Tree Condo Pet Scratcher Tower Small Black Sisal Scratch Post, 1996). The soluble protein may have commercial use as gelatines,Foska Mini Size High Quality Heavy Duty Stapler, peptides or amino acids production (5.5X19mm Hex Head Self Tapping Screws with Washer, 1991;Industrial PVC High Pressure Oxygen Acetylene Twin Welding Sealing Double-Color Gas Cutting Flexible Air Hose, 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;Low Volume Hard Tool Kit Thermoplastic Polymer Injection Molding., 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.24 Hours Self-Service Water ATM Machine Automatic RO Water Vending Machine.
