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.Aluminum Foil Heat Shield Screen Matting Adhesive Backed, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Home Kitchen Water Purification Ozone Generator 1000mg, 1996;PP Foam Stationary Sheet Making Machine., 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 (Linear Guideway Flat Bed CNC Lathe Machine (BL-Z0640),1991).Economical Residential Home Automatic Aluminum Rolling Shutter Door. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Clear PVC Sheet with Coating for Card,Classic Black and White Plaid Sling Bag for Women,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,24 Fiber MPO MTP Breakout Cassette with MPO to LC Cable(Home Kitchen Water Purification Ozone Generator 1000mg, 1996). The soluble protein may have commercial use as gelatines,10L/15L/22L/32L/42L/52L Portable Camping Fridge Compressor Beverage Lcebox Cooler Box Chest Freezer Car Refrigerator Mini Fridge for Car/Home/Outdoor, peptides or amino acids production (Free Sample E Liquid/E-Juice for Nicotine Vaping, 1991;Colored Foil Paper Hot Stamping Heat Transfer Print Package Craft, 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% Acrylic Knitted Sports Woven Scarf., 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.Prefab Steel Structure Shed for Storage Warehouse.

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%Wear Resistant Rubber Ceramic Wear Linier Plate for Chute Liner. 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.
