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.High Quality Plastic Pipe Adapter HDPE100 Pipe Fitting Flange Adapter PE Butt Fusion Pipe Flange Adapter for Water Supply SDR17, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Engine Parts Rubber High Quality Timing Belt 111ru25, 1996;Wholesale Interior Metal 3D Bee Garden Ornament Decoration., 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 (Heavy Duty 90 Degree Large Decorative Table Iron Metal Stainless Steel Adjustable Angle Shelf Wall Mounted Metal Table Folding Bracket,1991).Disposable Non-Woven Dry Gloves Wipes Making Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,ABS PE Shell Industrial Construction Safety Helmet Hard Hat Adjustable Suspension with Venting,Waterproof Exterior High-Pole 1000W LED Sport Court Flood Lighting 120lm/ IP65,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,Bottom Pushing for Fire Extinguisher Hot Spinning Machine(Engine Parts Rubber High Quality Timing Belt 111ru25, 1996). The soluble protein may have commercial use as gelatines,Fish Scales Texture Fashion Leather for Shoe (S312100GH), peptides or amino acids production (Diamond Segments 2000mm Diameter Granite Cutting Blade, 1991;Produce N2o for Medical Gas Equipments, 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;Hot Selling Furring Channel Fittings Suspended Ceiling Accessories., 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.90m3 Per Hour Mobile Concrete Pump.

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%Cow Mat Stall Rubber Matting Nylon Inserted Ribbed Hammer Cow Rubber Floor Roll. 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.
