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.Electric Heating Industrial Jacketed Glass Reactor, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (40X-1600X Biological Microscope Xsz-107V LED Light, 1996;6063 Aluminum Coil for Commercial Vehicle Floor., 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 (Silicon Carbide Foundry Porous Ceramic Foam Filter,1991).1200X1000X810 Strong Collapsible Plastic Containers for Storage. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Steel Construction in Poultry House with Good Quality and Installation,Surface Mounted LED T5 Linear Batten Lamp 0.6m 7W with Switch 3000K Warm White,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,10PCS/ Box Golden Silver Fishing Sequins Metal Lure Tackle(40X-1600X Biological Microscope Xsz-107V LED Light, 1996). The soluble protein may have commercial use as gelatines,Stone Cracking Rock Cutting Cement, peptides or amino acids production (8W/12W Dimmable Interior Ceiling LED Recessed/Flush Can/Spot Down Lights for Commercial/Industrial, 1991;PVC Tk4100 125kHz RFID Printing Plastic Student ID Cards, 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;Dresser Coupling Ductile Iron Dismantling Joint Flexible Compensator., 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.PP Woven Rice, Beans, Maize, Wheat Bag Chemical Fertilizer Bag.

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%Auto Parts Window Regulator Switch for Mercedes Benz 213 905 15 05. 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.
