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.Paper Egg Box Forming Molding Production Line/ Egg Tray Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (4K LED TV Panel Laser Repair Machine Cr-512dh Big Size Panel Repairmachine/LCD Screen Repair Machine, 1996;Tan Color Strip Aluminum and Glass Mosaic for Wall (M855330)., 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 (CNC Metal Grinding Machine Tool Mk2120,1991).Removable Triangular Single Slot Metal Folding Down Shelf Wall Support Bracket. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hot Sale High-Order Elasticty Girls Sports Wear Yaga Suit,Cast Iron Trivet for Tableware Dia: 21cm or Customize OEM,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,12V Electric Winch with 2500lb Pulling Capacity for Lifting / Portable Electric Winch(4K LED TV Panel Laser Repair Machine Cr-512dh Big Size Panel Repairmachine/LCD Screen Repair Machine, 1996). The soluble protein may have commercial use as gelatines,Hydraulic Electric Stationary Car Platform Scissor Elevator Lift, peptides or amino acids production (Australia Standard Structural Steel of Steel Structure Hangar As4100 Airport Building, 1991;Dark Red Teflon Encap Silicone O Ring, PTFE Encap Silicone O Ring for Industrial Seal, 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;Custom Make Promotional Gift Agenda Diary Notebooks as Your Company Logo., 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.N52 Strong Disc Neodymium Rare Earth Permanent Industrial Cylinder Magnet.

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%HD Night Vision IR Laser Camera with PTZ for 1200m Surveillance. 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.
