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.15W Aquarium Submersible UV Lamp Durable Germicidal Lamp, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (2019 Hot Sales Comfortable Mesh Chair Computer Staff Chair Ow-J219b, 1996;Accept OEM New Products Team Various Colors Gold Ribbon., 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 (Hnx Wholesale High Quality Metal Brass Standard Nutsert Lock Nut,1991).Stainless Steel Expanded Metal Mesh/Aluminum Expanded Metal Mesh. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,24V Ultrasonic Fogger 100mL Aroma Diffuser LED Light,Home Furniture Set Restaurant King Throne Wedding Banquet Dining Chair,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,What′s Kind of Machine for Making Organic Fertilizer Granules(2019 Hot Sales Comfortable Mesh Chair Computer Staff Chair Ow-J219b, 1996). The soluble protein may have commercial use as gelatines,Gsjl 91/1 Multibar Computerized Jacquard Warp Knitting Machine, peptides or amino acids production (Home and Hospital Electric Patient Lift, 1991;Coloured Glaze Material and 1000mm Length 333mm Width Fish Scale Asphalt Roofing Shingles, 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;M4 Pneumatic Air Driven Liquid Booster Pump Various Good Quality., 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.Motorcycle Intake Manifold Carburetor Interface Connector Joint Motorcycle Parts.

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%Q35y-30 Ironworker Shearing and Punching Machine Ce Approved Q35y Hydraulic Iron. 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.
