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.40A C Electronic Air Circuit Breaker with Dz47-4p, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Pipe Thermostat with Sensor Ce Certificate, 1996;Walking Long Distance Surveying Instrument Meter Measuring Wheel., 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 (Chinese Supplier of PVC Profile,1991).Tianjin Manufacturer PTFE Coated Butterfly Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Inflatable Sup Surfing / All Round / Race Stand up Paddle Board Surfboard,Wholesale Prices of 20W 40W 60W Solar Street Lights,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,Sinicline Custom Brand with Plastic Pouch Hangtag for Hats(Pipe Thermostat with Sensor Ce Certificate, 1996). The soluble protein may have commercial use as gelatines,Legit Human Chorionic Gonado-Tro-Pin 5000iu H-Cg Powder, peptides or amino acids production (Plastic Kitchen Organization Sink Caddy Sponge Holder Saddle Bag, 1991;VRLA Deep Cycle Storage Battery 12V 100ah (QW-BV100A), 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;ALS Stage 5W RGB Animation Laser Light., 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.Multifunctional Solar Powered Safety Hammer LED Flashlight, Alarm Fescape Rescue LED Torch.

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%Vacuum Coating Machine Water Chiller (CW-6300AN). 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.
