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.Quality Shaper Machine Bc6085 Shapping Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Thermoplastic Road Marking Paint Glass Beads, 1996;Automatic Best Price Small Plastic Pet Drink Water Juice Bottle Jar Maker Blow Molding Blowing Making Machine., 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 (Large Variety Low Volume Non Standard Customized High Precision CNC Machining Parts,1991).I7s Twns Bluetooth Earphone Sport Stereo Earbuds 4.2 with Charging Case. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Polyvinyl Chloride Suspension Resin Virgin PVC Resin Sg5,Free Sample! AC Power Contactor for Sale,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,PA System Loudspeaker 100W Outdoor Column Speaker (Thermoplastic Road Marking Paint Glass Beads, 1996). The soluble protein may have commercial use as gelatines,Semi Automatic 240cups Professional Commercial Espresso Coffee Machine for Hotel, peptides or amino acids production (Breathable Surgical Disposable 3 Ply Earloop Face Mask, 1991;Butt Welding Fittings/Elbow 90d Lr/Sr/ ASTM A234 Wpb Sch40/ ANSI B16.9, 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;Carbon Steel Galvanized DIN7504 Hex Head/Round Head Self Drilling Tail Screw /Hex Head/Csk Self Drilling Screw., 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.Ce Approved Single Roller Electric Heated 2.5m Ironing Machine/Calender Iron 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%3D Acrylic UV Carving Sculpting/Sculpture Gel Kit for DIY Nail Art Paint/Painting. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
