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.Chinese Top Manufacturer Aluminium LED Profile for LED Linear Light, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Aluminum Carpet Topping Stage Platform, 1996;BY60100C type metal shaping machine/hydraulic shaper 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 (Full Print Women Wholesale Custom Track Clothing Men Polyester Sweat Suit Hoodies,1991).China Spplier 70W Solar Street Light with Camera Monitoring System. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Reflective Pavement Markercat Eyes Reflector Brightness Aluminum Road Stud,Office Supplies Flexible Plastic Writing Clip Board PP Foam Clipboard,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,Anti-Counterfeiting Adhesive Seal Tamper Evident Security Warranty Void Tape(High Quality Aluminum Carpet Topping Stage Platform, 1996). The soluble protein may have commercial use as gelatines,Excavated Caterpillar Loader Mining Tunnel Loader Mucking Loader, peptides or amino acids production (Sy09-05-003 Rubber Pet Grooming Massage Dog Cleaning Brush, 1991;Easy Installed Microwave Drying Equipment for Fish /Shrimp/Seafood for Small Factory, 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;Masturbators Adult Sex Toys Japanese Love Doll., 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.Cheap 20tons LPG Semi Trailers Gas Tank Transport Trailer for Sale.

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%High Quality Crawler Excavator Track Bolt 3p2274. 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.
