Lipase production by Candida rugosa was carried out in submerged fermentation. Plackett-Burman statistical experimental design was applied to evaluate the fermentation medium components. The effect of twelve medium components was studied in sixteen experimental trials. Glucose, olive oil, peptone and FeCl3.6H2O were found to have more significance on lipase production by Candida rugosa. Maximum...

Celite immobilized Lipase 4, an isoenzyme of commercial Candida rugosa lipase (CRL) obtained from the fungus, Candida rugosa has been catalyzed alcoholysis in dry ethanol of various triglycerides and soybean oil. The advantages of this process are that separation of the product is very easy and no additional solvent is required as alcohol acts both as a reactant and medium. The yield of monogly...

Two novel impedimetric biosensors for highly sensitive and rapid quantitative detection of diazinon in aqueous medium were developed using two types of lipase, from Candida Rugosa (microbial source) (CRL) and from porcine pancreas (animal source) (PPL) immobilized on functionalized gold electrode. Lipase is characterized to specifically catalyze the hydrolysis of ester functions leading to the ...

Transesterification of (+/-)-menthol using propionic acid anhydride and Candida rugosa lipase was performed in chloroform and water at different pressures (1, 10, 50, and 100 bar) to study the pressure dependence of enantioselectivity E. As a result, E significantly decreased with increasing pressure from E = 55 (1 bar) to E = 47 (10 bar), E = 37 (50 bar), and E = 9 (100 bar). To rationalize th...

The yeast Candida rugosa is a convenient source of lipases for science and industry. Crude preparation of Candida rugosa lipase (CRL) consists of several extracellular lipases. Isoenzyme profile depends on the culture or fermentation conditions. All isoforms are coded by the lip pseudogene family; they are monomers of 534 amino acids and molecular weight of about 60 kDa. They share the same cat...

Yeast lipases present a growing interest for the synthesis of novel compounds and development of technologies with biotechnological applications. A new yeast strain CMGB-CR6 isolated from oilpolluted soil was identified as belonging to Candida rugosa using morphological observations, the API 20C AUX and Biolog Microbial ID systems and PCR-RFLP of the 5.8S rRNA-ITS and 18S rDNA-ITS. The analysis...

Kinetics of lipase-catalyzed esterification of hexanoic acid and ethyl alcohol using the solvent-free system, surface coated lipase from Candida rugosa, had been studied. The effect of various parameters such as reaction time, reaction temperature, reaction kinetics, water removal and feasibility of solvent-free system had been focused. Candida Rugosa lipase was more effective than other li...
