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.20 Ton Small Vertical Plastic Injection Molding Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (White Hand Carved Angel Sculpture, Marble Child Statue for Garden, 1996;Foska Mini Size High Quality Heavy Duty Stapler., 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 (5.5X19mm Hex Head Self Tapping Screws with Washer,1991).Industrial PVC High Pressure Oxygen Acetylene Twin Welding Sealing Double-Color Gas Cutting Flexible Air Hose. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Low Volume Hard Tool Kit Thermoplastic Polymer Injection Molding,24 Hours Self-Service Water ATM Machine Automatic RO Water Vending Machine,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,Professional Plastic Plating Makeup Brush Set(White Hand Carved Angel Sculpture, Marble Child Statue for Garden, 1996). The soluble protein may have commercial use as gelatines,Stationary Air Cooled Permanent Magnet VSD Air Compressor China Atlas Copco VSD Air Compressor India Atlas Copco VSD Air Compressor Atlas Copco VSD, peptides or amino acids production (Ceramic Tile Plasma Ion Deposition Planting Functional PVD Vacuum Coating Machine, 1991;Road Construction Non Woven Needle Punched PP Non Woven Geotextile, 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;Wholesale Scented Flavor Flower Herbal Tea., 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.Q-Sub Subwoofer Professional Passive Speaker Loud Speaker Woofer.

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%2019 New Water Quality TDS Test. 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.
