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.Food Grade Material 304/316 Double Diaphragm Pumps, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Manufacturer Wholesale Welded Wire Mesh Large Dog Cage/Dog Run Kennels/Dog Run Fence Panels, 1996;FUJI Home Monarch Hotel Passenger Elevator Residential Building Elevator., 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 (High Power From Han′s GS 2000W Laser Cutter,1991).Glazing Fixed-Point Facade Mullion Curtain Wall Outdoor Indoor Glass Panel. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Widely Application Latest Designed Coffee Capsule Filling Packing Machine,Zipper Top/Bottom Stops MIM Stainless Steel Zipper Puller Zipper Slider Zipper Head for Pouch Bag Garment Jeans,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,18V Lithium Battery Powered Cordless Drill(Manufacturer Wholesale Welded Wire Mesh Large Dog Cage/Dog Run Kennels/Dog Run Fence Panels, 1996). The soluble protein may have commercial use as gelatines,High Density Rock Wool Wall Board with Thermal Insulation Performance, peptides or amino acids production (PVC Coated Welded Wire Mesh/Galvanized Welded Wire Mesh /Stainless Steel Welded Wire Mesh, 1991;Hot Selling DIY Blank Resuable Skin Care Breathable Cotton Muslin Facial Sheet Mask, 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;China Top 3 1000W 1500W 2000W 3000W 4000W 6000W CNC Automatic Loading Feeding System CNC Fiber Laser Steel Pipe Metal Tube Fiber Laser Cutting Machinery., 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.China PAC Water Flocculating Agent for Water Treatment.

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 Pressure CF8 CF8m Stainless Steel Socket Welded Ball Valve. 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 (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
