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.Environmental-Friendly/Lightweight/Fireproof/Soundproof EPS Sandwich Panel for Partition/Exterior/Interior Wall, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Electronic Pulse Gas Stove Burner Igniter Transformer Parts, 1996;CNC Turned Aluminum Anodized Auto Part., 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 (Air Cooled 2.8/3.0kw Single Phase Electric Start Portable Diesel Generator,1991).Commercial Vegetable Mushroom Coconut Meat Drying Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,4mm/5mm/6mm/8mm/10mm/12mm/15mm/19mm Tempered Glass/Flat and Curved Glass/Safety Glass,Headband Big Headphone EVA Bag Tool Case Specialized Storage Box,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,Hydraulic Fold-Bend Machine Hydraulic Bending Machine(Electronic Pulse Gas Stove Burner Igniter Transformer Parts, 1996). The soluble protein may have commercial use as gelatines,Delphi Control Valve 28239295 (622B), peptides or amino acids production (OEM Precision Aluminum Alloy/Zinc Alloy Die Casting, 1991;Hot Sale Ink Chip for Epson P6070/P7070/P8070/P9070 Inkjet Printers, 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;Bathroom Makeup LED Mirror Glass with Light., 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.Green PVC Coated Euro Fence Welded Wire Mesh Fence Garden Fence Euro Wire Fence.

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%20kg Net Weight Double Pleastic Bags Outer Carton Peanut Paste for Snack Factory. 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.
