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.Q35y-30 Ironworker Shearing and Punching Machine Ce Approved Q35y Hydraulic Iron, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Shenzhen Yizexin Numeric Keyboard Conductive Ink Membrane Switch, 1996;High-Tenacity Conveyor Belt/ Steel Cord Conveyor Belt., 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 (Hanwha SMT Chip Shooter LED Pick and Place Machine,1991).ACP Aluminium Cmposite Panel Cladding Extrusions. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Model Hydraulic Energy-Saving Disposable Paper Plates/Tray/Coaster Forming Making Machine,Wholesale Custom Mens Heated Down Jacket,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,Rectification Triming Metallized Polyester Film Slitting Rewinding Machine(Shenzhen Yizexin Numeric Keyboard Conductive Ink Membrane Switch, 1996). The soluble protein may have commercial use as gelatines,Temporary Aluminum Cat Eyes LED Reflective Road Raised Solar Pavement Marker, peptides or amino acids production (New Swim Shorts Grey Mens Board Shorts with Mesh Liner, 1991;Multifunction CNC Woodworking Machine with 1300*2450*200mm Working Area, 9kw Air Cooling Spindle, Nc Studio Control, 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;Small Potato Harvest Machine/Sweet Potato Harvesting Equipment /Batata/Spanish Potato Harvester (factory selling customization)., 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.Stucco Embossed Aluminium Cladding Polysurlyn 3003 H14 Sheet in Coil.

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%LED Light Therapy Beauty Equipment for Skin Care PDT Salon Machine. 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.
