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.PSF 1000 Flat Plate Upper Discharge separator, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aromatherapy Essential Oil Ultrasonic Diffuser with APP Remote Control Smart, 1996;Powerful Neodymium Pot Magnet Rare Earth Pot Magnet., 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 (CNC Gun Drilling Machine,1991).Dog Puppy Squeaker Plush Toy Training Chew Simulation Pet Products. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Whiteness & Excellent Dispersity Anatase Type Titanium Dioxide,Large Jewelry Display Box for Ring Necklace Earring Storage Case,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,Indoor Tub Customized Shower/Free Standing Shower Enclosure(Aromatherapy Essential Oil Ultrasonic Diffuser with APP Remote Control Smart, 1996). The soluble protein may have commercial use as gelatines,Glow in Dark Ceramic Sublimation Mug 11oz, peptides or amino acids production (Double Poles Number Bimetal Strip 1AMP Mini Circuit Breaker, 1991;Stainless Steel 201/304/316 CF8/CF8m 1000wog Threaded Ball Valve, 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;22-30L/H Commercial 3 Flavors Mix Soft Ice Cream Cones Maker Machine., 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.Supermarket Combined Island Chest Freezer Commercial Refrigerator.

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%HDPE Pipe for Water Supply (OD: 16mm-800mm). 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.
