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.Metal Galvanized Wave Form Perforated Steel Strips, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Melamine Wooden Like Plate/Bamboo Plate/ Dinner Plate (NK13811-12), 1996;Jqx62f Nc 100A 220VAC Coil Voltage Electromagnetic High Power Relay., 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 (Factory Good Quality Coral Fleece Children′s Bathrobes Kids Hooded Bathrobes Wholesale,1991).Silver Anodized Aluminium I Beam Level Measuring Tool. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Bluetooth Sports Watch 116plus Smart Bracelet Incoming Call Pedometer Heart Rate Monitor Blood Pressure Sleep Monitoring,48V25A Lead Acid Battery Maintenance Pulse Charger,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,15mm Best Price Commercial Grade Birch Plywood for Furniture(Melamine Wooden Like Plate/Bamboo Plate/ Dinner Plate (NK13811-12), 1996). The soluble protein may have commercial use as gelatines,Top Great Wallet Genuine Leather Purse with Coin Pocket, peptides or amino acids production (Good Price 20kVA Single Phase Silent Diesel Generator, 1991;Electric Hydraulic Three-Station Bus Bar Cutting Punching Bending Machine for Copper Processing, 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;Super Precision PTFE/Teflon/Peek/Upe Spring Energized Seals., 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.Factory Supply Decorative Plastic PVC Vinyl Siding Panels for Exterior Walls.

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%Original Cummins Genuine Auto Diesel Engine Assemblies Cylinder Block 3928797 for Nta855. 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.
