In the past few decades, there is increasing trend to use products from natural resources. Dyes obtained from natural sources are among such products. The present research mainly focuses on optimization of extraction conditions during a natural dye extraction from the flower petals of a tree ‘Flame of Forest’. Taguchi technique was employed for optimization of the parameters namely raw dyestuff...

variations in phosphatidate phosphohydrolase (pap) activity and triacylglycerol concentration were measured in pregnant and hormone-treated non-pregnant female rats. pap activity in adipose tissue was elevated by 61% during pregnancy. the increase in the enzyme activity was paralleled with a rise in serum triacylglycerol concentration (44%). estradiol injecting into non-pregnant rats increased ...

This study investigates the oil extraction from Pistacia Khinjuk by the application of enzyme.Artificial Neural Network (ANN) and Adaptive Neuro Fuzzy Inference System (ANFIS) were applied formodeling and prediction of oil extraction yield. 16 data points were collected and the ANN was trained with onehidden layer using various numbers of neurons. A two-layered ANN provides the best results, us...

We employed a urease-catalyzed reaction to gradually remove a high concentration of a chaotropic agent (urea) from a denatured protein solution and demonstrated that efficient protein refolding can be achieved by the urease-catalyzed reaction, without large-volume dilution.

Grape marc seeds contain large amounts of different polyphenolic compounds so they can be used for the recovery of these classes of compounds. A new green extraction method for the recovery of phenols from the grape seeds was developed. To provide a high quality extract sourced from natural product by using enzymes as alternative solvents and spending less energy, it is impeccable to call this ...
