Systems-level approaches for understanding and engineering of the
oleaginous cell factory Yarrowia lipolytica
Abstract
Concerns about climate change and the search for renewable energy
sources together with the goal of attaining sustainable product
manufacturing have boosted the use of microbial platforms to produce
fuels and high-value chemicals. In this regard, Y. lipolytica has
been known as a promising yeast with potentials in diverse array of
biotechnological applications such as being a host for different
oleochemicals, organic acid and recombinant protein production. Having a
rapidly increasing number of molecular and genetic tools available,
Y. lipolytica has been well studied amongst oleaginous yeasts and
metabolic engineering has been used to explore its potentials. More
recently, with the advancement in systems biotechnology and the
implementation of mathematical modeling and high throughput omics
data-driven approaches, in-depth understanding of cellular mechanisms of
cell factories have been made possible resulting in enhanced rational
strain design. In case of Y. lipolytica, these systems-level
studies and the related cutting-edge technologies have recently been
initiated which is expected to result in enabling the biotechnology
sector to rationally engineer Y. lipolytica-based cell factories
with favorable production metrics. In this regard, here, we highlight
the current status of systems metabolic engineering research and assess
the potential of this yeast for future cell factory design development.
