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.2019 Ce Approved Car Spray Booth /Furniture Infrared Paint Spray Booth, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Trending Hot Products Rotary Floor Cleaner Microfiber Cleaning Mop Bucket, 1996;5/8 Alco Drier Filter Refrigerator Liquid Line Filter Drier Gas Filter Ek-165 Flare Type., 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 (3*19.8 NRA G2 AISI420 Needle Roller for Bearing,1991).JIS G3461 STB410 Steam Steel Tube, JIS G 3461 ASTM A179 Seamless Boiler Pipe. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,3PC Ss Ball Valve with ISO 5211 Direct Mounting Pad,PVC Connector Sleeve Soft Plastic Battery Terminal Covers,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,Eco Friendly Recycle Paper Cheap Wholesale Custom Printing Colouring Hardcover Comic Children Board Book(Trending Hot Products Rotary Floor Cleaner Microfiber Cleaning Mop Bucket, 1996). The soluble protein may have commercial use as gelatines,Wiiboox High-Precision Exquisite Detail Effect Printing Machine LCD 3D Printer, peptides or amino acids production (Portable Mini Fridge with Light Box, 1991;Agriculture Film for Corn Silage Wrap Baler, 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;Cheap Gabion Wire Mesh Box., 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.Stainless Inox Escalator Decorative Panel 304 Grade Brushed Stainless Steel Sheet with 7 PVC Film.

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%Concrete Floor Grinding Disc Machine for Four Segments. 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.
