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.Three Phase 35kv Current Transformer for Indoor, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Shipping Logistics to Stockholm, 1996;CNC Lathe Main Parts with Good Quality., 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 (Good Price High Torque 12mm Low Speed Small Geared Motor,1991).Custom Small Size 4.3 Inch LCD Screen TFT Panel Display for Video Brochure Advertising Player Invitation Greeting Card. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fashion PU Rhombic Style Crossbody Bag Waist Bag for Woman and Man,Waterproof 100W 100 Watt LED Flood Light for Tennis Court Lighting,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,Chemical HPMC Kraft Paper Bag with PP Woven Fabric Laminated(China Shipping Logistics to Stockholm, 1996). The soluble protein may have commercial use as gelatines,Mashroom Head Nylon Anchor with Pozi Nail, peptides or amino acids production (Outdoor Tempered Glass Aluminum Frame Sunroom for Swimming Pool, 1991;Waterjet 87K Intensifier Part Check Valve Body 020077-1, 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;Meat Machinery/Chicken Breast and Fish Slicing 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.Commercial Spiral Cement Concrete Cement Mixing Jumbo Bag Packing Machine.

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%Bread Box Bamboo Large Capacity Roll Top Bread Holder Cupcake Storage Food Bin for Loaf Pastry Snacks. 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.
