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.Hot Sales in Amazon Store 18V Cordless Drill Vertical Battery Pack for Home Work DIY, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3 12 Strand 3mm 4mm 5mm 10mm 18mm Braided Dan Line Plastic PP Packing Hollow Polypropylene Rope, 1996;Self Adhesive Paper Stickers 13.56MHz NFC Anti-Theft Security RFID Label Tags for Alcoholic., 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 (Leisure Men′s Waterproof Strap Light Cross Body Anti-Theft Chest Bag,1991).Wholesale Aluminum Touring Pre-Rig Lighting Truss with Wheels. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,43 Meters Truck-Mounted Boom Pump/Pump Truck/Concrete Pump,Aluminum Adjustable Quick Assemble Stage with Steps,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,Hardware CNC Machinery Milling Part(3 12 Strand 3mm 4mm 5mm 10mm 18mm Braided Dan Line Plastic PP Packing Hollow Polypropylene Rope, 1996). The soluble protein may have commercial use as gelatines,Customized 8 Layers Round LED Panel Aluminum PCB for LED Light, peptides or amino acids production (Basic Style Buffalo Leather Safety Shoes Ce Certificate S3 (SN1388), 1991;Gamicos Wireless Diesel Fuel Fuel Oil Water Tank Level Gauge, 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;Stainless Steel Ss304 Sanitary Hoop Union (ACE-HJ-G3)., 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.Resistant Flame Retardant Fiberglass Cloth Aluminum Foil Tape.

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%Disposable Environmental Biodegradable Takeaway Box Fruit Salad Box with Cover. 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.
