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.Wholesale High Quality Metal Car Mount Holder Phone Holder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Biggest Factory Titanium Dioxide Rutile Industrial Grade for Painting, Masterbatch, 1996;High Aluminum Insulating Ceramic Fiber Paper for Industrial Kilns., 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 (Pet Laminate Aluminium Foil/Pet+Alu+PE,1991).6 Ton Mini Excavator Wheel Digger Machine with Rotation Hydraulic Gapple Factory Directly Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,New Design Multi-Color Silicone Coin Purse for Lady,Common Rail Injector Control Valve F00rj01451 for 0445120064/074/136/137/424/363/362/246/234/139/074/138/065,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,Portable Folding Table for Camping, Picnic, Outdoor, Family Party Form Camping Kitchen(Biggest Factory Titanium Dioxide Rutile Industrial Grade for Painting, Masterbatch, 1996). The soluble protein may have commercial use as gelatines,Dark Green Plastic PVC Film for Christmas Tree Leaves, peptides or amino acids production (Desktop 3-Axis Automatic Fluid Dispensing Machine with Case and Monitor, 1991;Pure Peptide Powder PT-141 for Enhancing Male Power with GMP (ODM), 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;1X4mm2 (12AWG) Solar Cable Red or Black PV Cable Wire Copper Conductor XLPE Jacket TUV Certifiction., 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.Water Treatment Anthracite.

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%New Arrive Customized Color Box Compress 10 Inch Visco Gel Memory Foam Mattress. 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.
