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.OEM Double Sided Rigid PCB Circuit Board Manufacturer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Robot of World Robotics Competition, 1996;Professional Rope/Cable/Wire Braiding Machine with Factory Price., 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 (Aluminum PCB Circuit Board SMD PCBA LED PCB,1991).Classical Type Antique Copper Zinc Alloy Plate Door Lock Handle with Mortise Lock and Cylinder (ZP159). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Concrete Pump Sponge Cleaning Ball for Concrete Pump Truck,China Supplier Steel Machine Bellows Cover Telescopic Shield Cover,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,Concrete Cure Spray Concrete Curing Agent(Robot of World Robotics Competition, 1996). The soluble protein may have commercial use as gelatines,Automatic Chewing Dog Food Snack Machine, peptides or amino acids production (White Ceramic Shot Glass for Sublimation Printing - 1.5oz, 1991;Promotional Gifts Custom Printed Silicone Wristband/Bracelet, 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;Industry Mega PVC Fabric Automatic Folding Hangar Rolling Shutter Door., 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.8000kg Diesel Forklift Great Logistic Equipment Fork Lift Truck 8ton.

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%Refrigeration Digital Temperature Controller Stc-100A. 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.
