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.4mm Vinyl Plank Floor Lvt Click Lock Wood PVC Spc Click Vinyl Flooring, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Novel in Design Plastic Injection Mold Tooling for 15L Dustbin Bucket Mould, 1996;Custom Stainless Steel Double Small Torsion Spring., 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 (1 Inch NPT Screwed Globe Valve,1991).Industrial Rubber Nylon Conveyor Belting Automotive Parts. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Aluminium Insert MDF Factory-Slotted Groove MDF in 12mm 15mm 18mm,Small Leather Shoes Craft Laser Cutting Machine,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,Protection Plate Custom Sheet-Metal Fabrication by Professional Workshop(Novel in Design Plastic Injection Mold Tooling for 15L Dustbin Bucket Mould, 1996). The soluble protein may have commercial use as gelatines,Baby Toothbrush Kids Silicone Finger Brush, Baby Finger Toothbrush, peptides or amino acids production (Durable Comfortable Rubber Non Slip Mouse Pad Wrist Rest, 1991;China Manufacturer Industrial Aluminum Floor Bar Grating, 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;Food Grade Stainless Steel Milk Dairy Equipment for Factory., 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.Sun-160 Full Automatic Electric Driven Weighing Cups Filling Packing Machine.

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%Bobcat Skid Steer Loader Bucket Teeth 6737325lp. 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.
