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.China Top Roof Tiles Making Machine with Reasonable Price, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stylish Summer Safety Shoes Protective Toe and Midsole Slip Resistant Work Shoes Sc-8803, 1996;Large Capacity Food Processing Cooling Tower Conveyor Equipment., 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 (China Factory Custom UV Protection Plastic PVC Window Door Profiles PVC Profiles UPVC Window Profile,1991).Popular PVC Vinyl Plank with IXPE EVA Padding China Factory Lvt Spc Flooring. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel 304 Sanitary Pipe Fitting Weld / Tri Clamp /Reducing Tee,40g Stainless Steel Mesh Scourer Net Bag Packing Galvanize Wire Mesh Pot Scourer /Zinc Coated Scrubber / Pot Scourer,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,Pillow Case Automatic Sewing Machine Bc901(Stylish Summer Safety Shoes Protective Toe and Midsole Slip Resistant Work Shoes Sc-8803, 1996). The soluble protein may have commercial use as gelatines,Aluminum Lamp Body 90mm Cut out Square LED COB Downlights, peptides or amino acids production (Customized Malleable Casting Iron Threaded Pipe Fitting Flange Cast Iron Flange, 1991;Metal Tin with Clear Lid, 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;Ouwave China Factory Wholesale Air Purifier Smart Scent Machine., 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.Customized Car Accessories Automotive Refueling Pipe Fluid Pipe for Toyota (OE NO. 77201-44161).

The final soluble protein shown were used for peptides separations using gel permeation chromatography,CNC Machinery Aluminum and ABS Mock up Prototypes.

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%Bsp 60° Male Cone Seat Carbon Steel Fittings. 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.
