abstract = {Controlling the morphology of filamentous fungi is crucial
to improve the performance of fungal bioprocesses.
Microparticle-enhanced cultivation (MPEC) increases
productivity, most likely by changing the fungal morphology.
However, due to a lack of appropriate methods, the exact
impact of the added microparticles on the structural
development of fungal pellets is mostly unexplored. In this
study synchrotron radiation-based microcomputed tomography
and three-dimensional (3D) image analysis were applied to
unveil the detailed 3D incorporation of glass microparticles
in nondestructed pellets of Aspergillus niger from MPEC. The
developed method enabled the 3D analysis based on 375
pellets from various MPEC experiments. The total and locally
resolved volume fractions of glass microparticles and hyphae
were quantified for the first time. At increasing
microparticle concentrations in the culture medium, pellets
with lower hyphal fraction were obtained. However, the total
volume of incorporated glass microparticles within the
pellets did not necessarily increase. Furthermore, larger
microparticles were less effective than smaller ones in
reducing pellet density. However, the total volume of
incorporated glass was larger for large microparticles. In
addition, analysis of MPEC pellets from different times of
cultivation indicated that spore agglomeration is decisive
for the development of MPEC pellets. The developed 3D
morphometric analysis method and the presented results will
promote the general understanding and further development of
MPEC for industrial application.},
