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.High Freqency PCB with Blind Via, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Strong Aluminum Armrest Reclining Hydraulic Barber Chair, 1996;Factory SMD3528 60LEDs/M Flexible LED Strip., 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 (Hot-Press Small Continuous Diamond Saw Blade Cutting Disc,1991).Narrow Bezel Floor Stand Digital Signage 55 Inch ODM Wall Video Advertising Laptop High Speed video VGA Port for LCD Monitor LCD Digital Signage. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Adjustable High Voltage Operating Rod Stick Telescopic Hot Stick,Comfort Furniture Natural Spring Memory Foam Mattress,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,Acrylic Sew-on Mirrors, Mirror Acrylic Sew-on Pieces, Sew on Acrylic Mirrors Crystal Flat Back Mirror Beads for Mirror Costume(Strong Aluminum Armrest Reclining Hydraulic Barber Chair, 1996). The soluble protein may have commercial use as gelatines,4.2A Type a Type C Pd QC3.0 USB Charger, peptides or amino acids production (Ferrous Sulphate Monohydrate 30%Min Factory Wholesale, 1991;Small Portable Scooters Folding Electric Scooters for Adults, 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;Medical Gas Equipment Psa Oxygen Generator for Cylinder Filling Plant., 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.DC Power Supply 80A From Three Phase Input to DC Output Battery Charging Cabinet.

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%Fast Delivery Malleable Iron Pipe Fitting Hexagon Nipple. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
