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.7inch Desktop 1080P Media Player MP5 Car Monitor with AV Input, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Price Decorative Wrought Iron Stairs Aluminium Metal Garden Fence, 1996;Kubota Combine Harvester Spare Parts 5h484-2392 Nut., 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 (Nellcor SpO2 Extension Sensor Cable 5 Core SpO2 Adapter Cable,1991).HVAC Contactor /Air Conditioner Contactor /Definite Purpose Contactor. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Steel Floor Deck Post Cutting Cold Roll Forming Machine,Similar Kavo8000b Fiber Optic Turbine with Water Volume Adjustable Coupling (KV180),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,Fluorous Rubber Coated Fiberglass Cloth(Wholesale Price Decorative Wrought Iron Stairs Aluminium Metal Garden Fence, 1996). The soluble protein may have commercial use as gelatines,Sinotruk Spare Parts Differential Planetary Gear with Part No. Az9231320152, peptides or amino acids production (280-350-500-550ml Glass Water Bottle with Sleeve (Customized Design Pattern), 1991;PS Foam Disposable Fast Food Box Making 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;K Helical Bevel Gearboxes Reducer Motor., 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.Indoor Customized Electronic Lighted LED Neon Open Sign.
