Expression of furfural reductase improved furfural tolerance in Antarctic bacterium pseudomonas extremaustralis
Whole-cell biocatalysis using Antarctic bacteria is presently hampered by a lack of genetic information, limited gene tools and critically, a poor range of cultivation conditions. In this work, biological engineering strategy was employed for developing Pseudomonas extremaustralis, a metabolical...

| description | Whole-cell biocatalysis using Antarctic bacteria is presently hampered by a lack of genetic information, limited gene
tools and critically, a poor range of cultivation conditions. In this work, biological engineering strategy was employed
for developing Pseudomonas extremaustralis, a metabolically-versatile and biopolymer-producing Antarctic bacterium,
as a new whole-cell biocatalytic host. For this purpose, gene cloning and plasmid construction were carried out for
overexpression of furfural reductase (FucO), an industrially-important enzyme for degradation of toxic furfural
compound commonly found in lignocellulosic biorefinery. FucO gene from Escherichia coli BL21 was cloned in
pJM105 plasmid and transformed into competent cells of P. extremaustralis to generate a biologically-engineered
pFucO strain. For functional characterization of the enzyme, furfural reductase activity was assayed, where the P.
extremaustralis pFucO strain exhibited increased furfural reductase activity of about 15.6 U/mg, an 18.8-fold higher
than empty plasmid-carrying control pJM105 strain (0.83 U/mg). Furfural detoxification activity using whole cells was
also determined by which the overexpression of FucO led to increased tolerance and cell growth with an OD600 value
of 5.3 as compared to the control pJM105 strain that was inhibited with 10 mM furfural during 48-hour cultivation.
Therefore, the findings obtained in this study successfully demonstrated the development of P. extremaustralis as
biocatalytic host for the production of recombinant furfural reductase. The bioengineering would serve as a modular
biotechnological platform for polar strain and bioproduct development tailored towards industrial biotechnology
applications. |
