abstract = {Microbioreactor (MBR) devices have emerged as powerful
cultivation tools for tasks of microbial phenotyping and
bioprocess characterization and provide a wealth of online
process data in a highly parallelized manner. Such datasets
are difficult to interpret in short time by manual
workflows. In this study, we present the Python package
bletl and show how it enables robust data analyses and the
application of machine learning techniques without tedious
data parsing and preprocessing. bletl reads raw result files
from BioLector I, II and Pro devices to make all the
contained information available to Python-based data
analysis workflows. Together with standard tooling from the
Python scientific computing ecosystem, interactive
visualizations and spline-based derivative calculations can
be performed. Additionally, we present a new method for
unbiased quantification of time-variable specific growth
rate based on a novel method of unsupervised switchpoint
detection with Student-t distributed random walks. With an
adequate calibration model, this method enables
practitioners to quantify time-variable growth rate with
Bayesian uncertainty quantification and automatically detect
switch-points that indicate relevant metabolic changes.
Finally, we show how time series feature extraction enables
the application of machine learning methods to MBR data,
resulting in unsupervised phenotype characterization. As an
example, t-distributed Stochastic Neighbor Embedding (t-SNE)
is performed to visualize datasets comprising a variety of
growth/DO/pH phenotypes.},
