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.Custom Design Plush Panda Animal Slippers Comfort Foam Support by, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Best 6-Axis Electric Screwdriver Machine Robot, 1996;Custom CNC Milled Precision Spare Part CNC Pen Automobile Parts., 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 (Galvanized Chain Link Wire Mesh/Diamond Wire Mesh/Chain Link Fence,1991).FTTH Embedded Type Sc Fiber Optic Fast Connector. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Multi-Function Small Tree Digging Shovel/Tree Machine,Automatic L Bar Sealer Shrink Tunnel 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,Full Automatic Carbonated Water Filling Full Line(Best 6-Axis Electric Screwdriver Machine Robot, 1996). The soluble protein may have commercial use as gelatines,2 Slots 40e2 Nice Industrial Machine LED Strip Aluminum Profile, peptides or amino acids production (Superior Watertightness JS Polymer Cement Waterproof Coating for Basement, 1991;PS 200 Upper Discharge Centrifuge, 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;3D Printer Use Small Bearing Support Units Sfu1610 Ballscrew., 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.Fashion Men′s Clothing Shop Interior Design Clothes Store Fixtures.

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%Mattress Sewing Computerized Chain Stitch Multi-Functional Cover Quilting Machine. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
