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.Galvanized Hexagonal Wire Mesh Gabion / Gabion Box, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (10X20FT Outdoor Folding Pop up Marquee Canopy Gazebo Tent for Sale, 1996;Must 4kw 2HP Pump Power Inverter Ags Bts Available., 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 Sale Small Steel Silo for Poultry Feed,1991).Good Price Nasal Paste Packaging Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Powerful Full Hydraulic Safework Certificates Hgy13 15 17m Mobile Concrete Placing Booms,High Hardness Industrial Aluminum Extrusion Alloy Profile for Table Frame and LED Light Frame,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,Cheap Factory Price Wholesale Mini Vape Disposable Pod Vape Refillable Device(10X20FT Outdoor Folding Pop up Marquee Canopy Gazebo Tent for Sale, 1996). The soluble protein may have commercial use as gelatines,Reverse Rolled Wedge Wire Screen/ Jonson Screen Plate, peptides or amino acids production (Ce Apporved New Model Aluminum 10W/15W/20W/25W/30W COB LED Downlight, 1991;Barbed Wire Right off The Border Wall to Protect Homes, 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;Big Discount Mosquito Protection Window Screen Anti Mosquito Net Insect Screen., 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.OEM Factory/Chrome Steel/ISO Certificate/Used in Machine/Pillow Block Bearings/Bearings/Bearing (UCP).

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Single Board 3.7V~24VDC Microwave Detector PCB.
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%Automatic Chicken Nipple Drinker System. 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.
