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.Galvanized Solar System Mounting Bracket Connector, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Digital Programmable Ntc Temperature Controller, 1996;Water Meter Spare Parts Rubber Rings for Sealing., 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 (Stainless Steel HK Series Needle Roller Bearing HK0408,1991).Road Construction Fabric Non-Woven Geotextile 200GSM. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Polymer Modified Cement Based Elastic Waterproof Coating,Best Thermal Insulation Material Aerogel Powder for Greenhouse Steam Pipe,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,Heat-Sealed Laminated Bag with Hexagonal Bottom Gusset(Digital Programmable Ntc Temperature Controller, 1996). The soluble protein may have commercial use as gelatines,Fashion Shoulder Backpack Handbag School Bag, peptides or amino acids production (Coating Application CMC / Coating Material Grade CMC LV, Mv, Hv / Coating Material Grade CMC Medium Viscosity, 1991;Hot Sale Cute Food Plastic Pet Slow Feed Dog Bowl, 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;FTTH Fiber Optic Fusion Splicing Toolkit., 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.High Speed Cable Wire Winding Braiding Machine.

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%Hex Thin Head Nut. 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.
