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.Rectangular Lunch Tin Box with Handle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Inflatable Cheering Stick for Promotional Gift, 1996;Alcohol/Ethanol Distillation Equipment Complete Alcohol/Ethanol Distillation Equipment., 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 (Built in Two Speakers 12.1 Inch Touch Screen USB Monitor Display for PC or Notebook,1991).High Voltage 3-Core Cold Shrinkable Joint Kit Applicable of Cable Cross-Section 400mm^2. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Customized Stainless Steel Door Lock Strike Plate Metal Lock Bracket,2 Inch Schedule 40 ASTM A182 316 90d Bw Lr Elbow,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,Mini Outdoor Hydraulic Man Aluminum Lift(Inflatable Cheering Stick for Promotional Gift, 1996). The soluble protein may have commercial use as gelatines,Cheap Price Roof Wall PU Sandwich Panel Press, peptides or amino acids production (Eco-Friendly Sun-Proof Black Metallic Thread with Beautiful Luster for Dress Use, 1991;industrial aluminum foil roll 8011 8079 1235, 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;Hospital ICU Portable Electric Injection Syringe Pump Ce ISO Approval., 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.High Flex Mdr 26 to SDR 26 Power Over Cable with Thumbscrews Locking and PVC Jacket.

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%100%Rayon Red Satin Dyeing Fabric for Women Dress. 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.
