“…However, the drawbacks of plant extraction, such as poor yield, high production costs, the scarcity of feedstock and the severe environmental damage, restrict their industry use [ 3 , 5 , 6 ]. Researchers focus on using microbial fermentation to produce α-farnesene as a result, and numerous efficient methods have been used to modify microorganisms to enhance the biosynthesis of α-farnesene, such as enhancing the α-farnesene biosynthesis pathway, blocking the downstream α-farnesene biosynthesis pathway, rewriting the central carbon metabolism, compartmentalizing the supply ways of precursors, relieving the inhibition of cell growth and optimizing the metabolic process [ 3 , 4 , 7 , 8 , 9 ]. In the previous study, we constructed an α-farnesene high-producing strain, Pichia pastoris X33-30, by the dual regulation of cytoplasm and peroxisomes [ 3 ].…”
