The growing demand for food and biofuels urges the vegetable oil processing industry to adopt cleaner technologies to mitigate the environmental pollution caused by chemical refining processes. Over the past decade, several enzymatic methods have proven to be efficient at reducing the generated waste, but improving the benefit-cost ratio is still necessary for the widespread adoption of this technology. In this work, we show that lecithin:cholesterol acyltransferase from Aeromonas enteropelogenes (LCAT) provides a higher extra-yield of soybean oil than a type A1 phospholipase (PLA) enzyme currently commercialized for soybean oil deep degumming.

Substrate pri-miRNA recognition by DCL1 requires two double stranded RNA binding domains located at the C-terminus of the protein. We have previously shown that the first of these domains, DCL1-A, is intrinsically disordered and folds upon binding pri-miRNA.

Extremophilic microorganisms are a rich source of enzymes, the enzymes which can serve as industrial catalysts that can withstand harsh processing conditions. An example is thermostable β-glucosidases that are addressing a challenging problem in the biodiesel industry: removing steryl glucosides (SGs) from biodiesel. Steryl glucosidases (SGases) must be tolerant to heat and solvents in order to function efficiently in biodiesel.

Recently, we described an enzymatic process for removing SGs from biodiesel. However, industrial adoption of this technology was hindered by the cost of the steryl glucosidase (SGase) enzyme used.
