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.High Efficiency Fine Powder Vibrating Screener, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Waterproof UHF RFID Button PPS Laundry Tags for Laundry Management, 1996;Plant Stands & Accessories Glass Hanging Flower Pot Bracket., 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 (Wooden Frame Stretched Canvas, Painting Canvas,1991).Automatic Transparent Film Medicine Box Chewing Gum Food Sealing Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,SPCC Material Light Gray Color 7.5u Height 144 Port LC 288 Core Adapter and Pigtail Full Loaded Rack Mount Optical Distribution Frame ODF,UF Membrane Aqu160 with Competitive Price and High Quality,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,Atf-805 Auto Car Transmission System Flushing Machine(High Quality Waterproof UHF RFID Button PPS Laundry Tags for Laundry Management, 1996). The soluble protein may have commercial use as gelatines,43 Glass Beads Cat Eye Aluminum Road Stud, peptides or amino acids production (Hot Sales Csutomized Printed Shipping Address Sticker Label (JP-s041), 1991;High Precision C45 Steel CNC Lathe Parts, 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;I12 Tws Wireless Blue Tooth Headsets with Charging Box I10 Earbuds for Iphonex/Xs Max., 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.CAS 9067-32-7 Hyaluronic Acid/ Sodium Hyaluronate.

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%Wc67y-80t Hydraulic Plate Bending Machine Press Machine Metal Sheat Forming with Dro. 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.
