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.Industrial Cast Steel Flanged One Way Swing Check Valve Nrv, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Black White Stone 925 Silver Cross Pendants Necklace Jewelry, 1996;Heated Outdoor Winter Battery Neoprene Fiber Heating Vest for Keep Warm for People., 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 (Kt Board Acrylic CCD Camera CNC Knife Cutting Machine,1991).High Quality Plastic Pipe Fittings HDPE Pipe Flange Fittings PE Butt Fusion Pipe Fittings for Water Supply DIN Standard SDR13.6 and SDR17. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fireproofing Durability 100% Virgin Polypropylene PP Twist Fiber for Airport Runway Reinforced,Soundless (Silent, Noiseless) Cracking Agent (SCA) for Breaking Rocks,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,Drilling Self Tapping Screw with PVC Washer 4.8/5.5/6.3(Black White Stone 925 Silver Cross Pendants Necklace Jewelry, 1996). The soluble protein may have commercial use as gelatines,China Factory Prices Custom Precisely A380 ADC12 Aluminum Die Casting Part, peptides or amino acids production (Compostable Ecofriendly Ecosource Leakproof Bento Lunch Box, 1991;Garvenment Projector High Mast Stadium Lighting High Power Lamp Outdoor LED Flood Light with 400 Watts, 5700 Kelvin, 277 Volts, 60 Hz, 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;Atlas Copco 30kVA 50kVA 100kVA 150kVA 200kVA Diesel Generator., 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.Carbon Steel Stainless Steel Countersunk Head Hollow Bolt.

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%China Soundproof Construction Foam PVC/WPC Board. 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.
