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.White Crystal Powder Betaine Anhydrous CAS#107-43-7, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Creative New Product Coin Holder Keychain, 1996;Auto Ignition Coil for Germany Car 330905115A 330900115A 0221502007 0221502008., 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 (Weak Daylight Recharge All in One Solar Street Light,1991).Ybz16-150/140 Vane Steering Hydraulic Pump. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 New Style Short Sleeve Maxi Muslim Dress for Women Plus Size Lady Dresses,3mm Indoor Wall Cladding Decoration Aluminum Composite Material,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,240*375*25mm Rectangle Galvanized Steel Access Panel for Air Duct Maintenance Cleaning(Creative New Product Coin Holder Keychain, 1996). The soluble protein may have commercial use as gelatines,Automatic CNC PU Sandal Pouring Machine, peptides or amino acids production (Glass Disc Suspension Insulators, 1991;2 Kw Steam Turbine Generator Stainsteel Steel Steam Generator, 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;Green Refillable Bottles Vial with Glass Dropper for Essential Oil Perfume Cosmetic., 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.Polypropylene Fibre for Commercial Slabs.

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%Electro Galvanized Low Carbon Straight Cut Wire. 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.
