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.New Stype Indoor and Outdoor Playground Plastic Slide with Swing for Paly Set, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Toregal New Design Outdoor Crystal Acrylic Wedding Chiavari Chair, 1996;Uic Standard Railway Type Y25 Bogie for Different Freight Wagon., 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 (Customized CNC Machining Plastic Rapid Prototype for Medical Tool Box,1991).Factory Truck/Bus Spray Paint Booth /Industry Paint Booth. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Enamelled Heavy Duty Cast Iron Skillet,Four Ranges Wide Monitoring From 8-100 Meters Via Encoder Beam Detector,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,Rd80 New Aluminum Alloy 3 Inch Industrial Chemical Resistant Water Diaphragm Pumps(Toregal New Design Outdoor Crystal Acrylic Wedding Chiavari Chair, 1996). The soluble protein may have commercial use as gelatines,Lab Equipment 3 Part Blood Cell Counter Auto Hematology Analyzer, peptides or amino acids production (Ball Mill, Grinding Mill, Mining Equipment, 1991;Used Tyre Recycling Plant for Reclaimed Rubber Production, 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;Fan Speed Controller RF Transmitter and Receiver Control Switch Kl-K201c., 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.Robe Pointe 10r Sharpy 280W Beam Spot Wash Moving Head.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%China Electric PCB Circuit Board with High Quality. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
