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 Quality CE Digital Display Adjustable Power Supply, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sales Foldable Rechargeable LED Book Reading Light with USD Charging 1.5 Wires, 1996;Parcel Tape Adhesive OPP Packing Tape., 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 (High Efficiency Non-Expensive Cracking Agent,1991).Fiber Optic Sc APC Fast Connector for FTTH Drop Cable. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Heavy Duty Trailer Lifting Hoist Manual Crank Hand Puller Winch,Custom Striped Compression Soccer Socks for Adults,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,Stainless Steel Kitchen Sink, Bar Sink, Wash Hand Sink (4738)(Hot Sales Foldable Rechargeable LED Book Reading Light with USD Charging 1.5 Wires, 1996). The soluble protein may have commercial use as gelatines,Mining Machine Dewater Screen Separator Coal Sand Sieve Shaker Dewatering Screen, peptides or amino acids production (High Tensile Strength Galvanized Steel Wire, 1991;24 Volt Fire Alarm Strobe Light Horn Strobe Sounder, 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;from China to Mexico Ciudad del Carmen reliable low cost Air Logistics Freight Shipping Forwarder., 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.Best Price PVC Coated Fiberglass Mesh Insect Window Screen.
