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.ALS Stage 5W RGB Animation Laser Light, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Multifunctional Solar Powered Safety Hammer LED Flashlight, Alarm Fescape Rescue LED Torch, 1996;Energy Saving Track Rail Dimmable 15W 20W 30W LED Track Light., 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 (Pet Anti-Static Needled Mat,1991).Dz/Bt-80h Multifunctional Full Automatic Cartoning Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,OEM Sheet Metal Fabrication for Aluminum Parts,Hwf Tsp Core Bit for Geotechnical Drilling,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,Price of Automatic Sludge Dewatering Machine(Multifunctional Solar Powered Safety Hammer LED Flashlight, Alarm Fescape Rescue LED Torch, 1996). The soluble protein may have commercial use as gelatines,Glass Bottle Juice Filling Rotary Type Aqua Water Liquid Beverage Rinsing Bottling Capping Labeling Packing Machine, peptides or amino acids production (Worm Gear Operation Wafer Lined F3 Butterfly Valve, 1991;Custom Printing A5 Elastic Bandage Leather Notebook with Emboss Logo School Notepad, 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;Wholesale New Fashion Leather Bag Lady Handbag Crossbody Bag., 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.Positive Drive Turn Belt for Spiral Freezing Equipment.

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%Road Construction Fabric Non-Woven Geotextile 200GSM. 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.
