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.Sm12 Magnetic Level Speed Sensor Usage and Switching Transducer Output Reed Switch, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fashion Jewelry 925 Sterling Silver Lucky Key Necklace for Women, 1996;Boat Deck Drainage Snow Rubber Flooring/Standing Desk Mat., 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 (Coil Sheet Automatic Feeder with Straightener Press Feeders Straighteners Uncoilers 3 in 1 Servo Feed-Straighteners Help to Making Electric Parts,1991).Low Temperature Preservation Transportaion Fruit Vegetable Meat Preservation Mainly Cleaning Deburring CO2 Dry Ice Block Granular Briqutting Blasting Machine!. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 Wholesale Electroplate Purple Glass Votive Candle Jar for Holidays,Plastic Pet Preform Stretch Blow Molding Machine Blowing Juice Baby Oil Milk Drink Water Bottle Making 4 Cavity Semi Auto PP Jar Manual Medicine Pharmaceutical,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,Samples Free! ! ! Primary/Remelted/Refined Lead Ingots(Fashion Jewelry 925 Sterling Silver Lucky Key Necklace for Women, 1996). The soluble protein may have commercial use as gelatines,Printed 10ml 15ml 30ml 50ml Glass Bottle Tincture Carton Paper Box with Custom Logo, peptides or amino acids production (120PCS/M Flexible LED Strip Tira De LED Light Strip, 1991;Durable Beige Wood Luxury Vinyl Flooring Dry Back/PVC Flooring, 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;Outdoor Portable Insulated Thermal Tote Cooler Bag for Lunch., 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.Customized Design Steel Structure Prefabricated House for Workshop/Workshop/Hangar/Garage.

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%Stainless Steel CF8/CF8m Street Elbow Pipe Fittings. 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.
