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.Products Genuine Leather En345-1 Steel Toe Cap Leather Safety Boots, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Toast Stamp Loaf Bread Tin Pan (ZMA), 1996;Cheap Price 30 50 80 100 150 200 Watt SMD Motion Sensor Outdoor Solar LED Street Light., 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 (ISO9001 & Ce Certificated Superfine Cocoa Cake Powder Grinder Mill,1991).Wiskind Hot-Rolled Low Cost Commercial Steel Structure Greenhouse. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Baking Soda 99.8% Min Sodium Bicarbonate,BS1387 Class B 2 Inch Sch40 Gi Pipe Galvanized,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,4in1 Functional Diamond Dermabrasion Hydra Deep Facial Cleansing Peeling Microdermabrasion Machine(Toast Stamp Loaf Bread Tin Pan (ZMA), 1996). The soluble protein may have commercial use as gelatines,6 Cavities Automatic Bottle Blow Moulding Machine / Pet Stretch Molding Machine/ Pet Bottle Blower, peptides or amino acids production (Chemical Equipment & Machinery Gas Station CO2 Beverage Aluminum Gas LPG Gas Cylinder, 1991;10g Non-Woven Fabric Silica Gel Desiccant, 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;Soosan Excavator Hydraulic Hammer for Construction Demolition., 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.Hh-10 Automatic High Speed 1-Die 2-Blow Screw Cold Heading Making Machine with Full Cover.

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%Private Label Customized Teeth Whitening Activated Charcoal Toothpaste OEM. 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.
