Abstract:: ... BACKGROUND: Several types of phospholipases have been described in phospholipids modification. The majority of phospholipase D (PLD) superfamily members can catalyze two separate reactions: the hydrolysis of phospholipids to produce phosphatidic acid (PA) and the transphosphatidylation of phosphatidyl groups into various phosphatidyl alcohols to produce modified phospholipids. Transphosphatidylati ...

Abstract:: ... Biodiesel is produced by transesterification reaction of oils catalyzed by homogeneous catalysts, with the latter being non-recoverable and promoter of solubility of the produced glycerol into the otherwise immiscible ester phase, which have to be purified. The need for purification of products is eliminated if heterogeneous catalysts are employed, with the added advantage of the catalyst recovery ...
