In the last decades, robotic cultivation facilities combined with automated execution of workflows have drastically increased the speed of research in biotechnology. In this work, we present the design and deployment of a digital infrastructure for robotic cultivation platforms. We implement a Workflow Management System, using Directed Acyclic Graphs, based on the open-source platform Apache Airflow to increase traceability and the automated execution of experiments.

In this study, a minimal cell approach was combined with genetic devices to overcome such issues. A flavin mononucleotide-based fluorescent protein (FbFP) was expressed in a proteome-reduced Escherichia coli (PR).

Clavulanic acid (CA) is produced by Streptomyces clavuligerus (S. clavuligerus) as a secondary metabolite. Knowledge about the carbon flux distribution along the various routes that supply CA precursors would certainly provide insights about metabolic performance.

The time-dependent development of cell polarizability and length in Escherichia coli batch fermentations were observed at-line with electrooptical measurements. While using a measurement system with fully automated sample preparation, the development of these properties can be observed with a comparable high frequency (six measurements per hour). The polarizability as well as the mean cell length both increase soon after inoculation and then decline from the growth phase on until the stationary phase is reached.
