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.China Factory Prices Custom Precisely A380 ADC12 Aluminum Die Casting Part, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Compostable Ecofriendly Ecosource Leakproof Bento Lunch Box, 1996;Garvenment Projector High Mast Stadium Lighting High Power Lamp Outdoor LED Flood Light with 400 Watts, 5700 Kelvin, 277 Volts, 60 Hz., 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 (Atlas Copco 30kVA 50kVA 100kVA 150kVA 200kVA Diesel Generator,1991).Carbon Steel Stainless Steel Countersunk Head Hollow Bolt. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Men Women Spring Hinges Reading Glasses Classic Real Wood Finish Readers +1.0~+4.0 Plastic Eyeglasses,China Supply Chisel Plow Swedged Spike Tip Chisel Point for Agriculture,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,Factory Supply Coaxial Cable Rg 59 with Messenger, HDMI Cable(Compostable Ecofriendly Ecosource Leakproof Bento Lunch Box, 1996). The soluble protein may have commercial use as gelatines,5ml Parfum Kenka Caneta Aluminium DOT Anodized Compact Glass Refillable Bottle Empty Pump Atomizing Spray Perfume Bottle, peptides or amino acids production (Clear PVC Roof Frame Tent in South Africa, 1991;High Sticky Tissue Paper Solvent Adhesive Double Sided Tape (DTS511), 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;Stainless Steel Bend Pipe for Industrial Use., 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.Ybz-E16f20 Vane Steering Hydraulic Pumps.

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%55 Sun Redable Vertical Floor Standing Outdoor Touch Interactive Advertising LCD Kiosk. 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.
