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.Metal Chrome Liners for Bomco F2200hl High Pressure Drill Mud Pump, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Polycarboxylate Based Concrete Plasticizer High Rate Water Reducing Admixture with Good Slumption Retention, 1996;Cylindrical Shape Beer Glass Bottle for Wine Storage., 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 (Plastic Injection for OEM Product,1991).HOWO Sinotruck Heavy Truck Parts Air Spring Suspension Wg1642110024. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Aluminum Truss System, Aluminum Lighting Truss, Roof Truss System for Event,Mobile/Cell Phone LCD for iPhone 6s Plus Phone LCD Touch Screen,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,Activated Carbon Strong Effect Peeling off Face Mask Mud(Polycarboxylate Based Concrete Plasticizer High Rate Water Reducing Admixture with Good Slumption Retention, 1996). The soluble protein may have commercial use as gelatines,Type Price Prefabricated Roof Tile in Sudan, peptides or amino acids production (Stackable Mahogany Color Wooden Chiavari Chair with Soft Cushion, 1991;Factory Supply 100% Natural Epimedium Extract for Male Health, 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;Stainless Steel Bathroom Accessories 304 Polished or Brushed Finish No Chrome No Rust., 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.Type 0242 IP67 220V-415V 6h 3p+E 3pin 32A Industrial Plug.

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%Tpo Waterproof Membrane/Thermoplastic Polyolefin for Rooofing. 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.
