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.Customized Stable Burn-in Test Equipment, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Wholesale Custom 100% Cotton Boys T-Shirt with Print, 1996;Industry 0.002mm Accuracy Checking Fixture., 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 (Promotional Customized PP Hand Fan, Plastic Folding Fan,1991).450mm 500mm Diamond Saw Blade with Good Sharpness for Reinforced Concrete Cutting. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Six Stations Pen Press Machine,FDA Approved Cryo + RF Best Ultrasound Radio Frequency RF Slimming 80K Cavitation Slimming Machine,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,Vertical Automatic Granule Bag Packing Machine(Wholesale Custom 100% Cotton Boys T-Shirt with Print, 1996). The soluble protein may have commercial use as gelatines,Continual Shearing Machine Rtorary Cutting Machine Shear Aluminum Coil, peptides or amino acids production (160lm/W Die-Casting Aluminum UFO 150W LED High Bay Light Fixtures, 1991;4000W Industrial High Power Pipe Plate Whole Cover Exchange Platform Metal Fiber Laser Cutter for Carbon/Aluminum/Stainless/Brass 3015gr, 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;Food Additives 99% Aspartame (APM) CAS 22839-47-0 with Best Price., 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.Small Manufacturing Tht/ Ai Double Wave Soldering Machine.
