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.Waterjet Intensifier High Pressure Cylinder Waterjet Cutting Machine Spare Part, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Supplier Single Person Fishing Boat Angler Pedal Kayak 10FT for Adults, 1996;Restaurant Elevator Lift for Kitchen Residential Hotel Dumbwaiter in China., 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 Alloy Architect Triangle Scale Ruler with Color Grooves (WW-TSR01),1991).Pipe Conveyor Belt, Ep Conveyor Belt/ Nn Conveyor Belt. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plain Makeup Bag Canvas Cosmetic Bag,14inch -16.5inch Student / Beginner Maple Laminated Viola with Free Viola Case, Viola Bow,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,1/2 Inch 4sh 4sp Steel Wire spiral High Pressure Hose(China Supplier Single Person Fishing Boat Angler Pedal Kayak 10FT for Adults, 1996). The soluble protein may have commercial use as gelatines,High Pressure Food Grade Forged Tube Screwed Connector Stainless Steel Pipe Fitting Casting Nipple, peptides or amino acids production (Handwear Muslim Islamic Jewelry Halal Ring Lovers Titanium Steel Ring Stainless Steel Jewelry, 1991;Factory Wholesale Qualited Polyester Padding Men Jacket, 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;5.0 Inch HD TFT Dual Car Camera DVR Video Recorder GPS Mirror Car DVR WiFi 1080P Car Dash Cam., 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.Food Grade Reusable Silicone Food Storage Bag OEM Manufacturer.

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%Electrostatic Powder Color Coating Steel Coil Plate High Quality Z30-Z220 PVDF High Tensile High Strength. 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.
