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.Flooded Type Water Cooled Screw Chiller, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Promotional Custom Embossed Cups with Logo Print for Office/Holiday/Birthday, 1996;Enameled Mini Cast Iron Casserole., 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 (Good Quality Tomato Sauce Making Machine,1991).Vitamin B1 HCl 98% Feed Grade. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,2018 TPR Clean Teeth Training Dog Pet Chew Toy,Good Quality Zinc Plated Slotted Hex Head Roofing Screw,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,Vertical Automatic Sachet Bag Water Juice Milk Liquid Filling Packing Pouch Machine(Promotional Custom Embossed Cups with Logo Print for Office/Holiday/Birthday, 1996). The soluble protein may have commercial use as gelatines,5050 LED Strip RGB Double PCB 12V IP20 Non- Waterproof, peptides or amino acids production (Polycarboxylate Ether/Water Reducer Water Reducer PCE Polycarboxylate Superplasticizer, 1991;High Quality Orthopedic Fiberglass Splint, 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;Amazon Hot Selling Kids Playing Pop up Goal., 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.Small Frame Hydraulic Press Machine for Bending Price.

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%ASTM A269 TP304L Annealed and Polished Stainless Seamless Steel Pipe. 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.
