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.PVC Cabinet Construction Board, White 18mm PVC Foam Board, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (2019 New Portable Mini Dental X-ray Machine, 1996;Ss Reduced Port 2000wog 1PC Screwed Ball Valve., 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 (China Origin High Quality Food Grade Sodium Dihydrogen Citrate Anhydrous,1991).China Prefab Steel Building for Garment Factory. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Dark Blue Color Texture Indoor Swimming Pool Glass Mosaic Tile,Cable Tray with ′t′ Slots,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,10 Gauge Galvanized Welded Wire Mesh for Construction Using(2019 New Portable Mini Dental X-ray Machine, 1996). The soluble protein may have commercial use as gelatines,High Quality Factory Inline Hockey Skate Puck, peptides or amino acids production (0.5mm Pitch PCB Board Auto Part Motorcycle Parts Engine Parts FPC Cable Wire Connector, 1991;201 301 304 Embossed Checkered Plate Stainless Steel Coil/Sheet, 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;Disposable PS Foam Fast Food Box Making Machine., 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.Suoer 12V 220V 3000W Pure Sine Wave Inverter (FPC-D3000A).
