abstract = {Microbial bioproduction of the aromatic acid anthranilate
(ortho-aminobenzoate) has the potential to replace its
current, environmentally demanding production process. The
host organism employed for such a process needs to fulfil
certain demands to achieve industrially relevant product
levels. As anthranilate is toxic for microorganisms, the use
of particularly robust production hosts can overcome issues
from product inhibition. The microorganisms Corynebacterium
glutamicum and Pseudomonas putida are known for high
tolerance towards a variety of chemicals and could serve as
promising platform strains. In this study, the resistance of
both wild-type strains towards anthranilate was assessed. To
further enhance their native tolerance, adaptive laboratory
evolution (ALE) was applied. Sequential batch fermentation
processes were developed, adapted to the cultivation demands
for C. glutamicum and P. putida, to enable long-term
cultivation in the presence of anthranilate. Isolation and
analysis of single mutants revealed phenotypes with improved
growth behaviour in the presence of anthranilate for both
strains. The characterization and improvement of both
potential hosts provide an important basis for further
process optimization and will aid the establishment of an
industrially competitive method for microbial synthesis of
anthranilate.},
