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.


Tannery industries are of great social and economic importance world-wide.Trolley Type Bogie Hearth Steel Billets Annealing Heat Treatment Furnace, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Teerte Square Flat Head Self Tapping Screw, 1996;Jdz-1030 High Precision Screen Printing Machine for Satin Ribbon, Cotton Tape, Elastic Tape, Lanyard., 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 (Bto 22 Electric Galvanized Razor Concertina Wire for Military,1991).Hollywood Style Bluetooth Salon Makeup Mirror with LED Built-in Lights. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Tonva New Design Water Pipe Making Extrusion Blow/Blowing Molding Machine,Hot Selling Military Large Event Marquee Tent Sale,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,High-Quality Pre-Seasoned Cast Iron Wok(Teerte Square Flat Head Self Tapping Screw, 1996). The soluble protein may have commercial use as gelatines,2/3/4 Wires COB 40W 50W LED Track Light with 15/18/25/38/60 Degree Beam Angle, peptides or amino acids production (Rebonded Foam Machina, Foam CNC Cutter, Foam CNC, Foam Cutting Machine CNC Wire Cutting Machine, Tape Edge Cutting Machine, 1991;Marine High Visibility Solas Reflective Tape, 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;24L Thermoelectric Cooler and Warmer Car Mini Car Fridge., 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.Nubuck Leather Safety Shoe with EVA&Rubber Outsole (SN5444).

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%Hydraulic Adapter and Connections for High Pressure Hose Hydraulic Fittings Double Pipe 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.
