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.Aerobics and Exercise Highly Durable Floors of Offices and Commercial Rooms, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (100ml Plastic E Liquid Vape Cig Juice Dropper Bottle, 1996;Eco-Friendly Round Head Screw Stud Flange Hexagon Bolt for Building., 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 (Polypropylene Woven 25kg 50kg Bags Wholesale Sand Bags,1991).2-25mm Co-Extruded Highlight PVC Foam Board. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,CNC Engraving Machine Laser Marking for Assembly Line,PP/PE Plastic Lawn Turf Gravel Grass Grid for Driveway Paver (PGG5050A-1),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,Personalized Transparent Waterproof Plastic Bag Wet Underwear Clear PVC/EVA Ziplock Packing Bag with Gusset for Swimwear(100ml Plastic E Liquid Vape Cig Juice Dropper Bottle, 1996). The soluble protein may have commercial use as gelatines,High Quality A3 High Speed Epson Head UV Printing Machine for Bottle Printing, peptides or amino acids production (12V/24V, Ts16949, Air Conditioner Fan for Difference Refrigeration Truck, 1991;nellcor non-oximax 7pin infant disposable sensor, 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;Power Solar Inverter with Full Power 3000W Converter., 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.Custom Made EPDM FKM Rubber Mechanical Seal Diaphragm for Valve.

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%65 Polyester 35 Cotton Fabric Camouflage Printed Fabric. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
