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.Stand 2.5t Electric Pallet Truck, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Full Body Neck Back Buttocks Vibrating Car Seat Massage Cushion, 1996;Racket Shape Flat Bamboo Sticks Kabob BBQ Skewers., 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 (Automatic Round Bottle Shrink Sleeve Labeling Machine for PVC Label,1991).Men Fashion Plaid Design Polyester Ties (WH24). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,70m Series Aluminiun Plastic Coated Profile for Widnows,New Arrival Wooden Kids Cleaning Set Toy for Education W10d251,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,Vertical Type Automatic Box Erector Machine(Full Body Neck Back Buttocks Vibrating Car Seat Massage Cushion, 1996). The soluble protein may have commercial use as gelatines,Air Cooled Scroll Type Water Chiller for Industrial Process, peptides or amino acids production (Pn6.3 8 10 16 3 4 5 Inch Water Supply Pipe and Plumbing Conduits Fittings Unplasticized Polyvinyl Chloride Pipes for Potable Cold Water Supplies China, 1991;Auto Part Front Brake Disc for Fortuner Kun51 2005-2012 43512-0K090, 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;Rotary Vibrating Sieve Machine for Compost., 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.I9s Tws Wireless Earphone Portable Bluetooth Headset Earbud.

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%10 Pieces Customized Professional Makeup Brush. 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.
