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.150kw Plastic Bottle Recycling Equipment, Plastic Pet Canister Recycling Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Speed Dispersion Machine for Paint High Speed Disperser Disperser Machine, 1996;CAS: 73-22-3 Betain Hydrochloric Feed Grade for Feed Animal., 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 (Women Luxury Handbags Leather Shoulder Bag,1991).P10 3X4m RGB LED Video Curtain for DJ Stage Backdrop. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Microfiber Beach Towel Fast Dry Towel, Outdoor Towel, Travel Towel, Swim Towel, Yoga Towel,Long Stroke Hydraulic Cylinder for Constraction 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,Neoprene Protective Elbow Protector Brace Elbow Support (NS0012)(High Speed Dispersion Machine for Paint High Speed Disperser Disperser Machine, 1996). The soluble protein may have commercial use as gelatines,Big Smart Plant Hydroponic Planter with Indoor Garden Light, peptides or amino acids production (Weight 1.5 to 2.0mm Thickness in 100 to 200cm Width Felt Fabric, 1991;High Quality Anti-Corrosion Fiberglass Sheet and Roll, 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;Durable Steel Retainer Plastic Road Safety Trench Cover., 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.Industrial Low Temperature Water Cooled Scroll Water Chiller.

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%Quantum Science Lava Stone Pendant Necklaces Scalar Energy Pendant. 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.
