Ethyl ferulate (EF) is a ferulic acid (FA) derivative with high commercial value. It is not found naturally and is mostly synthesized from FA via esterification with ethanol. The present work aimed to synthesize the EF from γ-oryzanol, a natural antioxidant from rice bran oil via acid-catalyzed transethylation at refluxing temperature of ethanol.

The RBAO was converted to the fatty acid ethyl ester (FAEE) and was used as the starting material. The dissolved γ-oryzanol was separated from the FAEE using an acid-base extraction method with alkaline aqueous ethanol and hexane as extraction media.

- Defective viruses hinder large-scale baculovirus production in insect cell cultures, prompting the use of a genetically defined virus inoculum for SeMNPV from Thailand.
- Targeted genotypes were purified and selected using techniques like plaque assays and PCR screening, focusing on the pif2 marker that indicates stable genotypes.
- Co-infection with a deletion genotype improved insecticidal activity significantly, demonstrating that strategic selection of genotypes can enhance baculovirus effectiveness for bioproduction.
