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.Socket Flange, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Dn32 (11/4) BSPT Thread Air Actuated Piston Valves, 1996;Free Sample Cheap Customized Elastic Nylon Fabric Woven Cloth Wrist Band for Events., 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 (Foam Cutting 9.0kw Atc Spindle CNC Wood Engraver Machine,1991).Disposable Sterile Twist Top Blood Lancet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Industrial Control Housing with Plate Shape (XD-CC04),Customized Precision Hydraulic Cylinder Metal Machinery Parts for Forklift,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,Low Fuel Consumption Diesel Generator Economic Diesel Power 80kw 100kVA(Dn32 (11/4) BSPT Thread Air Actuated Piston Valves, 1996). The soluble protein may have commercial use as gelatines,Wholesale Price Auto Iridium Spark Plug for Turbo Trumpchi Cars, peptides or amino acids production (CNC 3 Axis Milling Machining Center, 1991;Hot Sale Bathroom Downlight LED 10W Ceiling Light IP54 Spot Light Fitting, 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;Variable 50Hz 22kw AC Drive 3 Phase Frequency Inverter., 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.4 Axis CNC Woodworking Machinery Engraver Router.

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%New Condition Hot Sale Type Air Cooled Ice Cube Maker. 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.
