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.Natural Latex Pocket Coil Spring Mattress for 5 Star Hotel, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Flex Rigid Printed Circuit Board with UL Flex PCB for Electronic Products, 1996;Made in China Lqa Strap Banding Tool., 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 (New R&D Wire Cable Feeding Winding Machine,1991).Stainless Steel Manual Glass Kitchen Ajustable Pepper with Low Price. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Residence Use 220V 50Hz 12kw Portable silent Diesel Generator,Garden Decoration Marble Stone Granite Small Angel Sculpture Water Fountain,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,530ml Glassware/Glass Jar/Wine Bottle/Liquor Bottle/Spirits Bottle/Glass Vodka Bottle(Flex Rigid Printed Circuit Board with UL Flex PCB for Electronic Products, 1996). The soluble protein may have commercial use as gelatines,PCB Connector Pin Connector 1.0 Pitch Dual Row Pin Header, peptides or amino acids production (Sdlg LG936L Wheel Loader Spare Parts 4041000687 Hose Assembly, 1991;Galvanized Roller Shutter Window Torsion Springs, 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;100 Ton 200 Ton Bending Cutting Straightening Machine H Frame Hydraulic Press for Sale., 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.Carbon Graphite Crucible.

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%Parcel Tape Adhesive OPP Packing Tape. 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.
