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 Metal Stamping Parts Laser Cutting Aluminum Sheet Metal Fabrication, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Warm Women Suede Leisure Snow Boots for Winter (FF-1), 1996;Good Quality Xanthan Gum Application of Food with Best 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 (Wet Wire Drawing Machine for High Carbon Mattress Spring Wire,1991).120W Ultra Light Solar Blanket Panel for Camping, Caravan, Motorhome. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Effluent Treatment Ferrous Sulphate Heptahydrate 98%,Rechargeable 9V Li Ion Battery with Micro USB Charging Port,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,Transport System China Manufacturer for Table Belt Conveyor(Warm Women Suede Leisure Snow Boots for Winter (FF-1), 1996). The soluble protein may have commercial use as gelatines,Antique Gold/Copper Coin/Bright Gold/Copper London Ride Medal, peptides or amino acids production (Luxury PU Leather Wine Suitcase Storage Suitcase Travel Suitcase (1681), 1991;High Quality Mini LED Flood Light SMD Flood Light 50W, 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;Ferrite Core for Power Transformer (Ee16e)., 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.Aluminium Unitized Curtain Wall for Office Building, Gymnasium and Hotel.

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%Vertical Type Automatic Box Erector 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.
