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 Viton Mechanical Rubber Oil Seal, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rapid Prototype Plastic Molding Simple Rapid Tooling and Simple Mould, 1996;Dicalcium Phosphate 18% Granular DCP 18% Feed Grade Animal Nutrition Feed Additives., 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 (China Manufacturer PVC Layflat Hose, High Pressure Lay Flat Hose for Industrial Discharge,1991).400-600 Grit 201 304 Grade Polished Stainless Steel Pipe. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Meanwell LRS-35-24 35W 24V 1.5A Merchanical And Electrical Equipment With 3 Years Warranty Switching Power Supply,Wholesale 10kg 25kg Raschel Sacks for Packaging Vegetables,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,5 Axis CNC Machining Part Clear Anodize High Precision 3D Horizontal Scanner Extension Adjusting Nut(Rapid Prototype Plastic Molding Simple Rapid Tooling and Simple Mould, 1996). The soluble protein may have commercial use as gelatines,Variable 50Hz 22kw AC Drive 3 Phase Frequency Inverter, peptides or amino acids production (Nontoxic 3D/5D/7D Hot Press PU/Leather Car Mats for Toyota RAV4 Old and Newest Model, 1991;Car Interior Accessories Customized Car Seat Cover, 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;Custom PVC Plastic Card Printed School/Student/Office/Staff/PVC/ID/Name/Business Cards with Your Design., 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.10 X 10 Canopy Pop up Tent Outdoor Gazebo Tent for Exhibition.

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%Cosmetic & Food Grade Sodium Hyaluronate. 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.
