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.2/3/4 Wires COB 40W 50W LED Track Light with 15/18/25/38/60 Degree Beam Angle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rebonded Foam Machina, Foam CNC Cutter, Foam CNC, Foam Cutting Machine CNC Wire Cutting Machine, Tape Edge Cutting Machine, 1996;Marine High Visibility Solas Reflective Tape., 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 (24L Thermoelectric Cooler and Warmer Car Mini Car Fridge,1991).Nubuck Leather Safety Shoe with EVA&Rubber Outsole (SN5444). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Top Quality Waterproof IP66 Aluminum Die Cast Junction Box,Magic Tape Hook and Loop Fasteners,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,Watch Back Case Battery Cover Opener Wrench Screw Remover Repair Tool(Rebonded Foam Machina, Foam CNC Cutter, Foam CNC, Foam Cutting Machine CNC Wire Cutting Machine, Tape Edge Cutting Machine, 1996). The soluble protein may have commercial use as gelatines,Hot-Selling Aluminum/Aluminium Extrusion Profiles for Blinds Profile (RA-010), peptides or amino acids production (25-35 Cm NIBP Cuff Blood Pressure Cuff Disposable of Patient Monitor, 1991;Starch Doy Bag Packaging Machine, 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;High Quality 5PCS Pyrex Glass Bowl Set with Decals (TZ5-GB13G55-HCS-263A)., 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.Fashion Soft PVC Rubber Keychains for Promation Gift.

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%Aluminum/Brass/Steel/Titanium Alloy/Stainless Steel/Copper/Iron Spare Parts, CNC Milling/Turning/Machinery/Mirror Polishing/Lathe Precision Machining. 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.
