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.0.5L Plastic Pet Water Bottle Blower Molding Machine/Pet Bottle Making, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cheap Stainless Steel Mirror Home Panoramic 6 Person Residential Passenger Lift Elevator, 1996;High Temperature & IR Drying Electronic Oven / Furnace., 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 (Ce Approved Bowrider Leisure Boat for 6-8 People,1991).High End Folding Customized Golden Chocolate Paper Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,HD 1.3MP 360 Degree Panoramic Alarm IP Camera 960p Fisheye Wireless Camera with TF Card Slot IR 10m Yoosee,Industrial Original Cheap Brown Kraft Paper Core for Printer 0.5inches * 220mm,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,Concrete Electric Pole Pile Making Spinning Machine(Cheap Stainless Steel Mirror Home Panoramic 6 Person Residential Passenger Lift Elevator, 1996). The soluble protein may have commercial use as gelatines,Shop Front Indoor Durable Hanging Banner Advertising Signs, peptides or amino acids production (Cosmetic & Food Grade Sodium Hyaluronate, 1991;High Frequency Circular Vibrating Screen, 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;Fiberglass/Composite Mesh for Walkway FRP Grating., 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.High Quality 33kv 6.3kv 1000 kVA 50% Copper and 50% Aluminum Material Distribution Transformer Made in China.

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%Mini Outdoor Hydraulic Man Aluminum Lift. 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.
