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.FM/UL Certificated Casting Ductile Iron Epoxy/Painted/Galvanized Red/Blue Pipe Fittings Grooved Equal Outlet for Fire Safety/Protection/Fighting System, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Kwikstage Scaffolding System-Diagonal Brace, 1996;360 Rotating Automatic Touchless Car Wash Equipment with Drying System., 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 (48 Cavities of Plastic Pet Preform Injection Mold with Hot Runner,1991).Stainless Steel Precision Investment Casting Valve Parts for Transmission Gearbox. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,IN-G602 Portable Clinic Hospital Medical Machine Electronic Injection Single Channel Syringe Pump,Sell Rubber / EVA / PE/PVC Foam Board,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,Sodium Gluconate 98% Min Industry Grade for Chemical Admixture(Kwikstage Scaffolding System-Diagonal Brace, 1996). The soluble protein may have commercial use as gelatines,Brake Disc, peptides or amino acids production (DC 12V Cafe Coffee Shop Decorative LED Neon Flex China Custom Neon Sign, 1991;24volt Rechargeable LiFePO4 24V 100ah-a Li-ion Battery Pack for Marine Boat, 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;MP3 Wireless Bluetooth Car Audio Receiver Adapter with Remote., 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.Sarms Mk-677 Capsule /Mk 677 Powder Ibutamoren/ Mk677 Powder.

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%W11S-20X3200 Hydraulic Universal Three Rollers Sheet Plate Rolling Bending Machine. 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.
