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.Puffed Core Filling Sanck Production Machine with Ce From China, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (86 Inch All-in-One Android System Interactive Touch LCD Kiosk for Education/Meeting, 1996;Cummins Fuel Injector Kit (3076736 3095023)., 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 (Hnx IP68 Waterproof Nylon Plastic Cable Gland Pg13.5,1991).Matrix Keyboard 3X3 Matrix Membrane Switch PCB Membrane Keypad Switch. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plastic Therm Forming Filling Sealing Machine, Lid Press Machine,Electric 100W Three Wheels Toy Car for Sale,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,New Design Customized 100% Cotton Home Towel Bath Towel(86 Inch All-in-One Android System Interactive Touch LCD Kiosk for Education/Meeting, 1996). The soluble protein may have commercial use as gelatines,Toughened Railing Glass, peptides or amino acids production (Delrin Sheets with Good Wear Resistance, 1991;High-Power Safety Hammer Multifunctional Tool Flashlights with Rechargeable Battery, 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;Professional High Precision SLS/SLS 3D Printing Action Figure Parts Rapid Prototyping Service., 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.Spiral Rib Dies, Tungsten Carbide Spiral Screw Wire Drawing Dies.
