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.Silo Machine Equipment for Chicken Farm Feed Use (JF-A-L003), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cheapest Container Living House/Office/Kiosk, 1996;Spin Centrifugal Demister Separator or Column Internal., 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 (Baby Wet Wipe Machine,1991).Closed Impeller Centrifugal Pump Mining Pit Diesel Engine Drive Pump. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Shiny 100% Polyamide 280t 70d Plain Pleat Fabric Jacket Fabric,360 Degree Reciprocating Car Wash Machine,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,Temperature Sensor Customized Thermostat for Industrial Appliances(Cheapest Container Living House/Office/Kiosk, 1996). The soluble protein may have commercial use as gelatines,Custom Die Aluminum Castings, peptides or amino acids production (High Quality Meat Pie Making Machine with Different Mould Shape, 1991;Gear Operated Flanged High Performance Butterfly Valve, 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;China Supplier Sinotruk HOWO 6X4 Trailer Head Tractor Truck., 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.Stainless Steel Autoclave UV Sterilizer for Salon Yj-UV3.

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%Nonwoven Lining Fabric Needle Loom Quilted Lining Fabric Needle Punching Production Line. 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.
