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.8.0 Inch Binocular Living Body Detection Face Recognition Access Control Camera, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (WPC Wood Plastic Board Equipment Extruder Machine, 1996;Craft Socket & Wrench Tool Set Car Repairing Tools 94PCS., 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 (Neoprene Elbow Support,1991).Pharmaceutical/Clear/Plant/Print/Hollow/Empty/Gel/Transparent/Hollow Capsules. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,CNC Produce Medical Machining Custom Metal Milling,Multi Sensor Nilitary Surveillance Thermal Imaging Security camera,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,Custom Metal Stamping Welding Spare Parts for Farming(WPC Wood Plastic Board Equipment Extruder Machine, 1996). The soluble protein may have commercial use as gelatines,Flb-80125AC Automatic L Type Sealer Sealing Heat Hot Shrink Shrinking Shrinkable Film Wrap Wrapper Wrapping Pack Packing Packer Package Packaging Machine, peptides or amino acids production (Hot Sale Newest Multifunctional Ultrasonic vacuum RF Machine 5 MHz 40K Cavitation, 1991;275ml Frosted Clear Glass Drinking Bottle for Juice, 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;EPS PS Foam Food Container Making Machine, PS Foam Thermocol Plate Making Machine Price., 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.Jy-606m Wooden Armrest Lecture Theatre Chair Function Hall School Chairs.

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%Easy Foldable Kids Walking Chair Toys Baby Walker. 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.
