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.2017 New Design Vinyl 3D Stone Wallpaper Factory in China, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Custom Small Paper Gift Box with Magnet Closure for E-Cigarette, 1996;Agricultural Mini Tiller Farm Wheel 62cc Cultivator., 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 (0.8 Ton New China Small Hydraulic Bucket Crawler Mini Bagger Excavator with Cheap Factory Price,1991).Antique Brown Marble Mosaic Tile for Floor/Wall/Bathroom/Backsplash/Table/Patterns. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Efficient Online Hot Glue Dispensing Machine for Electronic Products,High Quality D400 FRP Composite Lockable Waterproof Round Manhole Cover and Frame BS En124,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,Marine Anemometer / Wind Meter/ Anemoscope with Alarm Function for Vessel/Ship(Custom Small Paper Gift Box with Magnet Closure for E-Cigarette, 1996). The soluble protein may have commercial use as gelatines,Automotive Sheet Metal Stamping Car Auto Parts, peptides or amino acids production (Garden Lamp Solar Powered Lighting 48LED PIR Motion Sensor with Remote Control, 1991;Indoor Cable 24 Core Multimode/Singlemode Fiber Optic Cable, 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;2019 Fashion New Styles Woman Shoulder Hobo Handbags PU Leather Ladies Crossbody Tote Bag W624-1., 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.Sedimentation Tank/Settling Tank/Lamella Clarifier for Sludge Wastewater separation.

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%Black Color Tube Eyelet Lift Gas Spring. 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.
