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.High Quality Warm Paste Packaging Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainless Steel Resin Trap Strainer, 1996;Small Bar Fridge with Glass Door for Beverage and Beer., 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 (Fcatory Supplu High Quality 7010b Low Price 2 DIN 7 Inch Car MP5 Player, Mirror Link and Built-in Bluetooth Car Radio Car Player,1991).Cheap Loader Xt860 Backhoe Loader with Digger. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2018 Private Custom Tungsten Carbide 2 Flutes Chamfer Drill Bit with 90 Degree Angle,Aroma Oils Diffuser Scent Machine HVAC System Perfuming Fragrance GS-10000,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,Lithium Battery 20ah Pouch 3c Cell 3.7V(Stainless Steel Resin Trap Strainer, 1996). The soluble protein may have commercial use as gelatines,Factory Custom 32 to 98 Infrared Transparent Video Wall Multi Touch Screen for Kiosk, peptides or amino acids production (Stainless Steel Handweel Three-Way Non-Retention Ball Valve, 1991;New Design Factory Supply Industrial Machine Pasta, 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;Ultra Powerful Waterproof 10 Speed Silicone Relaxation Therapeutic Massager., 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.500kg Capacity 14m Height Semi Electric Scissor Lift.

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%Automatic Controller Carbon Steel Sheet Pipe China CNC Plasma Cutter. 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.
