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.Gold Glass Dropper Bottle 20ml 30ml 50ml 100ml Spray Bottle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (HOWO 420HP Rhd Tractor Truck Head, 1996;Cummins Generator Set Diesel Engine Spare Parts Fuel Pump Support 4991549., 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 (Decorative Bathroom Illuminated Smart Backlit Rectangle LED Mirror with Blue Tooth,1991).Crankcase Breather Pipe Hose 11157542633 Fit for BMW E87 E90 E91 N46. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Supplier AC DC E27 Emergency Rechargeable LED Bulb LED Bulb,Gaint Inflatable Animal Slide,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,White 4*8FT 18mm PVC Foam Board for Cabinets Use(HOWO 420HP Rhd Tractor Truck Head, 1996). The soluble protein may have commercial use as gelatines,Dual Function Write Ball Pen Aluminum Stylus for iPhone Xs X Se, peptides or amino acids production (Multi Purpose Microfiber Towel Car / Home / Gift / Sport Towel, 1991;Power Plant Circulating Water Pump & Spare Part, 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;LED Strip Light SMD 3528 /SMD 5050/SMD 2835/SMD 5630 Rope Strip., 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.Carbon Steel Equal Tee for Connection of Pipe.

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%Sport Anti Vibration Hiking Safety Shoes. 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.
