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.T-Shirt Clamshell Heat Press Sublimation Machine (40X60cm), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Automatic Hydraulic Steel Sheet Bending Crimping Curving Machine, 1996;Double Shaft Horizontal Paddle Mixing Equipment for Detergent Powder., 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 (Mechanical Seal 101 Type for Pump and Auto,1991).Good Quality Pillow for Pregnant Wome Body Pregnant Pillow Case. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Good 0.38mm Color F-Green PVB Interlayer Film for Architecture Laminated Glass,China Soe Orthodontic Ceramic Sapphire Brackets Dental Material with Ce ISO FDA,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,2019 Newest Hybrid Shockproof Phone Case for iPhone Xs Max Xr X 8 7 6 Plus(High Quality Automatic Hydraulic Steel Sheet Bending Crimping Curving Machine, 1996). The soluble protein may have commercial use as gelatines,Whole Producing Line Salt Bath Bomb/Salt Tablet/ Salt Block Making Hydraulic Press Machine, peptides or amino acids production (Ipg 1000W, 2000W Professional Metal Pipe Laser Cutting Machine for 6m Metal Tube, 1991;3mm Acrylic Sheet Acrylic Board Acrylic Plate for Advertising Sign Board, 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 Pressure PU Filter Gasket Sandal 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.Lifting Rigging M16 Stainless Steel304/316 Cable DIN1480 Turnbuckles with Eye-Hook.
