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.Precision Engineering Parts Bearing Support Unit for Ball Screw, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (LED Table Lamp LED Desk Lamps LED Table Light 5W DC5V 1200mAh Modern Fashion LED Baby Study Light Lighting Eye Protection, 1996;165cm Realistic Full Solid TPE Sex Doll Big Breast Love Doll for Man., 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 (Silicone Cake Mold Sinle Cupcake DIY,1991).Plastic Pipe Clamp for Refrigeration Pipe System Pipe Fitting. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,10g Food/Pharmaceutical Desiccant Silica Gel for Moisture Absorbing,Cross Stripe Sleeveless Yoga Wear,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,Construction & Decoration ERW Square Steel Tube Manufacturer(LED Table Lamp LED Desk Lamps LED Table Light 5W DC5V 1200mAh Modern Fashion LED Baby Study Light Lighting Eye Protection, 1996). The soluble protein may have commercial use as gelatines,DVD Audio RCA Wiring Harness Cable for DVD Pioneer Avh, peptides or amino acids production (Black Steel ASTM A192 Seamless Pipe Sch120, 1991;China Excavator Radiator /Oil Radiator /Water Radiator Manufacture, 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;Canton Fair Galvanized Steel Aluminium Ibr Roof Sheet Roll Forming Making 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.BOPP CPP Laminate Food Packaging Metalized Pet Cup Sealing Film.

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%Wet Wire Drawing Machine for High Carbon Mattress Spring Wire. 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.
