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.Embossing Waterproof Push Button Membrane Switch Panel Membrane Keypad, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Plug-in Supermarket Chest Type Display Freezer with Sliding Glass Door, 1996;Hot Sell High Quality and Best Price Fitness Oval Tube Commercial Gym Equipment 8 Multi Station., 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 (Galvanized Pressure Locked Grating,1991).Phenol Polyoxyethylene Ether for Water-Reducing Admixture, 9004-78-8.. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2019 Ce Approved Car Spray Booth /Furniture Infrared Paint Spray Booth,Trending Hot Products Rotary Floor Cleaner Microfiber Cleaning Mop Bucket,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,5/8 Alco Drier Filter Refrigerator Liquid Line Filter Drier Gas Filter Ek-165 Flare Type(Plug-in Supermarket Chest Type Display Freezer with Sliding Glass Door, 1996). The soluble protein may have commercial use as gelatines,3*19.8 NRA G2 AISI420 Needle Roller for Bearing, peptides or amino acids production (JIS G3461 STB410 Steam Steel Tube, JIS G 3461 ASTM A179 Seamless Boiler Pipe, 1991;3PC Ss Ball Valve with ISO 5211 Direct Mounting Pad, 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;PVC Connector Sleeve Soft Plastic Battery Terminal Covers., 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.Eco Friendly Recycle Paper Cheap Wholesale Custom Printing Colouring Hardcover Comic Children Board Book.

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%Lightweight Adjustable Dorsal Ankle Night Splint for Pain Relief. 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.
