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.Vibratory Finishing Polishing Machine for Aluminum Brass Metal Steel Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage, 1996;Amber Green Blue Transparent Spray Perfume Bottle Glass Bottle for Perfume., 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 (Natural Cannabidiol Cbd Isolate Powder Cbd Powder Cbd Oil CAS 13956-29-1 China Supplier,1991).Two Head Mattress Machines Pocket Spring Coiling Machine Sewing Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,P-Level Sp-Level Mute Interchangeable Linear Motion Guide Rails,Heavy Zinc Galvanized and PVC Coated Binding Cut Iron Wire Stainless Steel Wire,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,Rectangular Stainless Steel Pipe SS304(Commercial Fitness Gym Strength Equipment Half Rack Body Solid Power Cage, 1996). The soluble protein may have commercial use as gelatines,High Efficiency Multistage Diesel Centrifugal Vane Pump for Chemical Industry, peptides or amino acids production (6.6kw LiFePO4 Charger for Lithium Battery Pack, 1991;Australian Merino Base Layer Ladies Wicking Breathable Anti-Odor Superfine Merino Wool Hoodie Pullovers, 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;50m Depth Long Range Metal Detector with Reliable Quality., 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.CNC Router with Auto Tool Changer for Woodworking (XZ1325/1530/2030/2040).

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%Customized Hot Forging Agricultural Spare Parts. 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.
