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.Test Inspect High Precision Nuts Go-Nogo Fixed Gauges Machine Tapping Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (60PCS/M LED 14.4W 20 Pixels DC12V RGB DMX512 IP65 Line Light, 1996;Solar Energy Storad Power Generation System., 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 (110V 140W Electric AC Induction Gear Motor (61K140GU-AFJ/6GU25K),1991).Custom Aluminum Cover Frame Half Aluminum Cover Profile. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Tire Rubber Powder Recycling Equipment for Sale Truck Tires Rubber Shredding Facility,DC24V 36W Solar Fan Motor PCBA Card,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 Monocular Hunting Wargame Mini Scope Digital Night Vision(60PCS/M LED 14.4W 20 Pixels DC12V RGB DMX512 IP65 Line Light, 1996). The soluble protein may have commercial use as gelatines,Dual Function Double Use Both Cut Steel Sheet and Pipe Tube Metal Fiber Laser Cutting Machine, peptides or amino acids production (Atlas Copco Ga VSD Air Screw Air Compressor High Quality Stationary Electric Screw Air Compressor, 1991;Italy Design Good Quality Hydraulic Motorcycle Lift Table, 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;Wholesale Menthol E Liquid E Juice for EGO E Cigarettes., 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.Biodegradable Kraft Paper Soup Cup Instant Noodles Bowls with Lids.
