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.Swimming Pool Water Disinfect Ozone Generator, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (20kv 50kVA High Voltage Dry Type Power Supply Transformer, 1996;Manufacturer Custom Injection Molded Plastic Shell of Automobile Headlamp., 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 (High Quality OS2 12 Core Singlemode High Density Data Center MPO-LC Breakout 2mm Low Insertion Loss 5m LSZH Fiber Optic Patch Cable Per Meter,1991).4 Styles Blue Glass Crystal Butt Beads Spiral Plug. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Electronic Automatic DC Motor Valve Industrial SUS Welded Ball Valve,Industrial Activated Carbon Water Filter Industry Water Treatment,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,2016 New Generation Sausage Making Machine(20kv 50kVA High Voltage Dry Type Power Supply Transformer, 1996). The soluble protein may have commercial use as gelatines,Magnetic Mixer Mixing Tank with Bottom Agitator (MTK), peptides or amino acids production (Wholesale Aluminum Frame Outdoor Advertising Pop up 3X3 Custom Portable Folding Gazebo Tent, 1991;New Christmas Alloy Colorful Animal Owl Tassel Earrings Cute Fashion Full of Diamond Studs (03), 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;China Supplier Building Construction Steel Frame (ZY431)., 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.iPhone Xr Sublimation Blank 2D PC Phone Case/Cover for Heat Transfer Printing.

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%Cuticle Aligned Raw Virgin Hair Easy to Dye Real Mink Brazilian Hair. 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.
