[PMID: 21145735 DOI: 10.1016/j.biortech.2010.11.074] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/10/2010] [Revised: 11/11/2010] [Accepted: 11/17/2010] [Indexed: 05/30/2023]
Abstract
An extracellular thermostable lipase from Amycolatopsis mediterranei DSM 43304 has been purified to homogeneity using ammonium sulphate precipitation followed by anion exchange chromatography and hydrophobic interaction chromatography. This protocol resulted in a 398-fold purification with 36% final recovery. The purified A. mediterranei DSM 43304 lipase (AML) has an apparent molecular mass of 33 kDa. The N-terminal sequence, AANPYERGPDPTTASIEATR, showed highest similarity to a lipase from Streptomyces exfoliatus. The values of K(m)(app) and V(max)(app) for p-nitrophenyl palmitate (p-NPP) at the optimal temperature (60°C) and pH (8.0) were 0.099±0.010 mM and 2.53±0.06 mmol/min mg, respectively. The purified AML displayed significant activity towards a range of short and long chain triglyceride substrates and p-nitrophenyl esters. Hydrolysis of glycerol ester bonds occurred non-specifically. The purified AML displayed significant stability in the presence of organic solvents (40%, v/v) and catalyzed the synthesis of the flavour ester isoamyl acetate in free and immobilized states.

Abstract
An extracellular lipase from Aspergillus niger NCIM 1207 has been purified to homogeneity using ammonium sulfate precipitation followed by phenyl sepharose and Sephacryl-100 gel chromatography. This protocol resulted in 149 fold purification with 54% final recovery. The purified enzyme showed a prominent single band on SDS-PAGE. The purified enzyme is a monomeric protein of 32.2 kDa molecular weight and exhibits optimal activity at 50 degrees C. One interesting feature of this enzyme is its highly acidic pH optimum. The isoelectric point (pI) of lipase was 8.5. The purified lipase appears to be unique since it cleaved triolein at only 3-position releasing 1,2-diolein. Chemical modification studies revealed that His, Ser, Carboxylate and Trp are involved in catalysis.

Abstract
Microbial lipases today occupy a place of prominence among biocatalysts owing to their ability to catalyze a wide variety of reactions in aqueous and non-aqueous media. The chemo-, regio- and enantio-specific behaviour of these enzymes has caused tremendous interest among scientists and industrialists. Lipases from a large number of bacterial, fungal and a few plant and animal sources have been purified to homogeneity. This has enabled their successful sequence determination and their three-dimensional structure leading to a better understanding of their unique structure-function relationships during various hydrolytic and synthetic reactions. This article presents a critical review of different strategies which have been employed for the purification of bacterial, yeast and fungal lipases. Since protein purification is normally done in a series of sequential steps involving a combination of different techniques, the effect of sequence of steps and the number of times each step is used is analyzed. This will prove to be of immense help while planning lipase purification. Novel purification technologies now available in this field are also reviewed.

Abstract
This work describes the hydrophobic interaction chromatography of homo-deoxyoligonucleotides polyA, polyT and polyU with sizes up to 30 bases on a Sepharose gel derivatized with the 1,4-butanediol diglycidyl ether. The oligonucleotides interacted differently with the column according to the molecular mass, the hydrophobic character of the individual bases, the secondary structure of the molecule and the concentration of ammonium sulphate in the eluent. The retention factor, k', was determined from the chromatographic profiles at different concentrations of ammonium sulphate. A linear relationship between log k' and the concentration of ammonium sulphate in the eluent was found for all oligonucleotides at the higher concentrations (> 1.0 M) of ammonium sulphate. The slope of these plots, termed the hydrophobic interaction parameter, was found to be an increasing function of the number of nucleotides. The same plots reveal that polyA molecules with high molecular mass have lower retention factors when compared with polyT, an observation that was not expected since the hydrophobicity of adenine is higher than that of thymine. This behaviour was due to the existence of secondary structures in polyA, which decrease the exposed hydrophobic area of the molecule.

Abstract
In this article, an overview of hydrophobic interaction chromatography (HIC) of proteins is given. After a brief description of protein hydrophobicity and hydrophobic interactions, we present the different proposed theories for the retention mechanism of proteins in HIC. Additionally, the main parameters to consider for the optimization of fractionation processes by HIC and the stationary phases available were described. Selected examples of protein fractionation by HIC are also presented.

Abstract
The adsorption behavior of bovine serum albumin (BSA) on a Sepharose based hydrophobic interaction support has been studied. Flow microcalorimetry has been used to determine the heat of adsorption under overloaded chromatographic conditions. These data have been complemented with capacity factor and isotherm measurements to provide insight on the mechanisms of adsorption. The heat of adsorption data have confirmed that the hydrophobic interaction adsorption of BSA under linear isotherm conditions is driven by entropy changes. Under overloaded (non-linear) conditions, however, it has been shown that the changes in enthalpy can drive adsorption; this behavior is not evident from analyses of capacity factor data. It is postulated that for BSA adsorption on the Sepharose derivative of interest, attractive force interactions between adsorbed protein molecules drive the adsorption process under overloaded conditions in a high (NH4)2SO4 environment. It is further postulated that these interactions are due to a change in confirmation of the adsorbed protein under these conditions.

Abstract
This work reports new studies on cellulases fractionation by hydrophobic interaction chromatography. The purification procedure for the Trichoderma reesei cellulase complex consists of gel permeation chromatography on Sephadex G-25M followed by an ultrafiltration step. The concentrated enzyme solution was then fractionated on Sepharose CL-6B modified by covalent immobilization of 1,4-butanediol diglycidyl ether. The influence of the mobile phase composition on the chromatographic behaviour of the T. reesei cellulase complex was investigated. By using 13% (w/v) ammonium sulphate in eluent buffer, a selective separation of beta-glucosidase with a two-fold increase in specific activity and a recovery of 60% cellobiase activity were obtained. Other commercial hydrophobic supports (octyl- and phenyl-Sepharose) were also tested and compared under the same conditions.

Abstract
The fractionation of Chromobacterium viscosum lipase was performed using a polypropylene glycol-Sepharose gel. The influence of mobile phase composition on the adsorption of lipase on the gel was studied and it was found that the retention of lipase depends on the salt used and increased with increasing the ionic strength. The retention was not strongly affected by changing the pH value of the mobile phase. By using 20% (w/v) ammonium sulphate in phosphate buffer a total retention of lipase on the column was obtained and by simply decreasing the ionic strength of the buffer, desorption of lipase could be achieved. The chromatographic purification of Chromobacterium viscosum lipase by hydrophobic interaction chromatography on Sepharose CL-6B modified by covalent immobilisation of 1,4-butanediol diglycidyl ether, polyethylene glycol and polypropylene glycol was also compared.
