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.Power 4 Leg Transmission Tower From Qingdao Wuxiao Group, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Blank Promotional Baseball Cap for Custom Logo Design, 1996;Metal Structural Steel Frame Structure Construction Prefab Warehouse Workshop Factory Storage Building., 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 (Five Axis CNC Flame/Plasma Pipe Cutting and Profiling Machine,1991).Aluminium Alloy Door Frame Profile. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,M16 M20 Stainless Steel Hilti Chemical Thread Bar Anchor Bolt Wedge Hex Bolt Sleeve Anchor Grade 5.6,High Quality 98% Feed Grade Betaine Anhydrous,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,Rubber Diaphragm Seals HNBR EPDM Rubber Diaphragm in High Quality(Wholesale Blank Promotional Baseball Cap for Custom Logo Design, 1996). The soluble protein may have commercial use as gelatines,Unisex Light Weight Quick Dry Sun Protection Sprots Jackets with Hood, peptides or amino acids production (Professional Pulse Dust Filter for Grain Processing, 1991;Plug-in Assembly Type Straight Through Joint and Insulation Joint, 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;DIN7505 Cross Recessed Countersunk Flat Head Chipboard Screws., 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.Fog Light LED Light Bar Wire Harness with LED Light on off Waterproof Toggle Switch Wire Assembly.
