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.Motor Bearing Automobile Bearing Self-Aligning Ball Bearing, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Asphalt Roofing Sheet Asphalt Shingle Roof Coating Architectrual Shingles, 1996;Downspout Pipe Roll Forming 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 (4mm Vinyl Plank Floor Lvt Click Lock Wood PVC Spc Click Vinyl Flooring,1991).Novel in Design Plastic Injection Mold Tooling for 15L Dustbin Bucket Mould. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Stainless Steel Double Small Torsion Spring,1 Inch NPT Screwed Globe Valve,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,Industrial Rubber Nylon Conveyor Belting Automotive Parts(Asphalt Roofing Sheet Asphalt Shingle Roof Coating Architectrual Shingles, 1996). The soluble protein may have commercial use as gelatines,Aluminium Insert MDF Factory-Slotted Groove MDF in 12mm 15mm 18mm, peptides or amino acids production (Small Leather Shoes Craft Laser Cutting Machine, 1991;Protection Plate Custom Sheet-Metal Fabrication by Professional Workshop, 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;Baby Toothbrush Kids Silicone Finger Brush, Baby Finger Toothbrush., 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.Durable Comfortable Rubber Non Slip Mouse Pad Wrist Rest.

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%Computerized Single Fishnet Jacquard Circular Knitting Machine. 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.
