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.Chinese Take-out Paper Food Boxes with Metal Wire Handle (GDNB-004), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Polyester Hunting Clothes Breathable Sniper Army Airsoft Uniform, 1996;55 Sun Redable Vertical Floor Standing Outdoor Touch Interactive Advertising LCD Kiosk., 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 (AMS-Tde-04 Snow Fat Tire 350W Electric Bike/Ebike/Electric Bicycle,1991).Low Power Consumption Silicone Sex Doll Vending Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Toughened Glass Disc Suspension Insulator,Yaye 18 Hot Sell 3 Years Warranty 70W LED Solar Street Light Lamp with 9100lm & Remote Controller,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,63A/105A CNC Plasma Metal Laser Cutting Machine 20mm Sheet Cutter(Polyester Hunting Clothes Breathable Sniper Army Airsoft Uniform, 1996). The soluble protein may have commercial use as gelatines,Customized Round Airless Lotion Pump Bottles for Skin Care Products, peptides or amino acids production (Round Shape Dinner Football Gift Bowl with Cover Plate, 1991;Professional Exporter of Wheat Flour Mill Plant (80t), 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;ASTM 316 304 420 Stainless Steel Welded Pipe Coil Tube., 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.Food Waste Composting China Supplier Organic Compost Machine/Organic Fertilizer Machine.

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%Automatic Mini Bag Spices Small Salt Packing Packaging Machine. 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.
