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.Jieshuai 3 in 1 USB Cable, Fast Charging Data Cable, Universal Micro USB Cable, Lightning Cable, Type C Cable, Suitable Apple iPhone and Android Charge, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Mini Electric Chain Saw Cutting Machine Price, 1996;A2 Grade Fireproof Customized Color ACP Sheet., 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 (Ce Approved Cheap Medical Disposable Electrical Infusion Pump,1991).Fashion Party Decoration Classic Wine Glass Accessories Jewelry. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Good Reputation Plastic Slide Swing Set, Indoor Kindergarten Plastic Kids Slides,32W Dimmable Interior Ceiling LED Recessed/Flush Can/Spot Down Lights for Cloth/Retail Stores,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,Galvanized Steel Barbed Wire Rope 8mm(Mini Electric Chain Saw Cutting Machine Price, 1996). The soluble protein may have commercial use as gelatines,CNC Aluminum Laser Milling Machinery, peptides or amino acids production (High Porosity Zirconia Zro2 Foam Filter for Foundry, 1991;Human Peptides Pentadecapeptide Bpc 157/Bpc-157 2mg 5mg for Anti-depression, 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;Disposable Nonwoven 3ply Medical Surgical Hospital Face Mask with Earloops., 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.Ribbon Mixer Plough Shear Mixer V-Shape Mixer Powder Mixer for Mixing Powder or Liquids.

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%6kVA Single Phase High Frequency Online UPS with 0.8/0.9 Power Factor. 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.
