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.PP/Pet Woven Geotextile for Road Construction, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Lamella Clarifier in Industrial Wastewater Treatment, 1996;FPC Hotbar Soldering with Exposed Lead Flex for PCB Soldering., 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 (Monochrome FSTN Positive Transflective Custom LCD Display St7567-G4d 128X64 Cog Graphic LCD Module with White LED,1991).Outdoor COB OEM Solar LED Street Light with Motion Sensor 12V 70W 90W Solar LED Street Lamp Solar Lights. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Candle Cups Patterned Glass Candle Holders Festival Decoration Glass Candlestick,Custom Colored ABS 3D Printing Parts Electronics Parts 3D Printing Plastic ABS Parts,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,IS Type Cast Iron Chemical Industrial Pump(Lamella Clarifier in Industrial Wastewater Treatment, 1996). The soluble protein may have commercial use as gelatines,Hot Sale Automatic French Fries Production Line Fresh Potato Chips Making Machine, peptides or amino acids production (Custom Grooved Quartz Plate Deep Processing, 1991;Hot Sale CNC Router Machine for Wood Cutting (1325), 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;Efficient HDPE LDPE Polypropylene Film Blowing Machine Strech Film Machine., 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.50g Body Luxury King Crown Cosmetic Containers.

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%Natural Cleaning Konjak Sponge. 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.
