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.16A 32 AMP 3 Pin Plug 220-240V Industrial Plug and Socket Male Female, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Oil Resistant Custom EPDM Rubber O Ring Washer Flange Valve Gasket Oring for Concrete Pump Pipe, 1996;200m Range Video DVR Imagers for Hunting Digital Infrared Night Vision., 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 (Fully Automatic Biodegradable Star Sealing Garbage Bag-on-Roll Plastic Trash Bag Making Machine Manufacturers,1991).Aerobic Fermentation Organic Fertilizer Agitator. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Oishi Chocolated Filled Corn Puffs Crisp Cereals Cracker Processing Equipment,CS1363 a Standard UK 3 Pin Power Plug,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,Insulation Anti Earthquake Exterior Wall Foam Board(Oil Resistant Custom EPDM Rubber O Ring Washer Flange Valve Gasket Oring for Concrete Pump Pipe, 1996). The soluble protein may have commercial use as gelatines,Zhongshan Factory Amusement Equipment High Quality New Design Crazy Dance Rides, peptides or amino acids production (Easy Soak off OEM 10ml Gel Nail Polish, 1991;Rope Making Machine for PP Danline Hawser Marine Mooring Rope Braiding Machine, 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;Recyclable PU Leather Jewelry Pouch., 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.Luxury Special Design Decorative Quality Gold Color Office Round LED Standing Floor Lamp (LT-11).

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%18K White Gold Octagon Emerald Cut Moissanite Diamond Jewelry Engagement Ring. 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.
