Biotransformation of ω-fatty acid – in search of erectile dysfunction treatments
Biotransformation can be defined as an application that utilized natural and recombinant organisms’ enzymes secreted by yeast, fungi and bacteria or whole cells as biocatalyst in synthesis of organic compound. Therefore, Pseudomonas aeruginosa bacterium has been chosen to be the biocatalyst for biot...
