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.Motorcycle Engine Parts Motorcycle Spark Plug for CB125/Xr150L, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cixi Kent Factory High Quality Inch Deep Groove Ball Bearing R10 R10zz R4 R188 R168 R3a R3 R166 R156 Use in Inch Bearing Place, 1996;Theme Park Inflatable Bouncer for Sale (BJ-B16)., 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 (Muliti-Size Light Hot Stamping Foil for PS Frame,1991).Waterproof Garden Yard Decoration LED Flame Solar Glass Jar Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,50W/80W/100W/150W/200W/240W/300W Industrial Workshop Warehouse Canopy Industrial LED High Bay Light for Indoor Natatorium Volleyball Badminton Sport Court,China 1 & 100 RMB Acrylic Currence Frame,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,1 Ton Toyo Type Manual Chain Block(Cixi Kent Factory High Quality Inch Deep Groove Ball Bearing R10 R10zz R4 R188 R168 R3a R3 R166 R156 Use in Inch Bearing Place, 1996). The soluble protein may have commercial use as gelatines,Spark Resistant Construction Axial Fan with Fixed Pitch Blade, peptides or amino acids production (Silicone Hand Pipe Hand Tobacco Pipes Smoking Pipe with Glass Bowl, 1991;3bbl Brite Servicing Tank Beer Brewery Equipment Unitank, Beer Making at Home, 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;25A DC-DC Single Phase Solid State Relay SSR (SSR-DD25)., 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.Precision CNC Milling DIN69871. Mas403 for CNC Machinist.

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%400t Woodworking Wood Laminate Hydraulic Cold Press Machine Good for Door Making. 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 (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
