Identification of a hot-spot to enhance Candida rugosa lipase thermostability by rational design methods

Isolation of Candida rugosa lipase isoforms

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...

Inhibition of Candida rugosa lipase by saponins, flavonoids and alkaloids

Structure-Based Rational Design to Enhance the Solubility and Thermostability of a Bacterial Laccase Lac15

Bacterial laccases are ideal alternatives of fungal laccases for specific industrial applications due to specific characteristics such as alkalescence dependence and high chloride tolerance. However, some bacterial laccases presented as inclusion bodies when expressing in Escherichia coli and showed thermal instability. In this study, rational design was employed to enhance the solubility and t...

Optimization of Candida rugosa lipase immobilization parameters on magnetic silica aerogel using adsorption method

Magnetic silica aerogel in hydrophobic and hydrophilic forms were used as support to immobilize Candida rugosa lipase by adsorption method. Response surface methodology (RSM) was employed to study the effects of the three most important immobilization parameters, namely enzyme/support ratio (0.3-0.5, w/w), immobilization time (60-120 min) and alcohol percentage (20-40, %v/v) on the specific act...
