abstract = {Hydrolases acting on polyesters like cutin,
polycaprolactone or polyethylene terephthalate (PET) are of
interest for several biotechnological applications like
waste treatment, biocatalysis and sustainable polymer
modifications. Recent studies suggest that a large variety
of such enzymes are still to be identified and explored in a
variety of microorganisms, including bacteria of the genus
Pseudomonas. For activity‐based screening, methods have
been established using agar plates which contain
nanoparticles of polycaprolactone or PET prepared by solvent
precipitation and evaporation. In this protocol article, we
describe a straightforward agar plate‐based method using
emulsifiable artificial polyesters as substrates, namely
Impranil® DLN and liquid polycaprolactone diol (PLD).
Thereby, the currently quite narrow set of screening
substrates is expanded. We also suggest optional
pre‐screening with short‐chain and
middle‐chain‐length triglycerides as substrates to
identify enzymes with lipolytic activity to be further
tested for polyesterase activity. We applied these assays to
experimentally demonstrate polyesterase activity in bacteria
from the P. pertucinogena lineage originating from
contaminated soils and diverse marine habitats.},
