Bioprocessing 4.0, the biopharmaceutical version of Industry 4.0, is defined as the digital transformation and automation of biopharmaceutical processes with the aim to drive manufacturing forward by increasing digitization and the interconnection of products, supply chains, and business models. Despite Bioprocessing 4.0 production concepts promise better process consistency with improved quality and safety for biologics, many biopharmaceutical companies still struggle to implement 4.0 production concepts and do not exploit the full potential offered by the digitalization and automation of manufacturing chains. The focus of this application note is on the Lucullus® Media Kitchen, a unique and valuable tool of the comprehensive software solution Lucullus®, for digitalized raw material and media management, contributing to paperless and more efficient workflows. Compared to manual process preparation, the demonstrated workflow offers complete digitalization of the process preparation phase and thus allows for process optimization by conveniently tracking the raw material footprint in the final product. In the end, critical material attributes that influence critical quality attributes can be understood and controlled, and supplier or lot issues identified to ensure final product quality.


Bioprocessing 4.0 production concepts are defined as end-to-end digitally interconnected and automated bioprocess systems and additional equipment, forming the Industrial Internet of Things (IIoT). Such ideal production concepts run, monitor, control, and even improve the process via feedback loops and advanced mathematical modeling approaches. Bioprocessing 4.0 production concepts generate huge amounts of process data and thus heavily rely on efficient data management to allow real-time monitoring and process control [1,2].

Unlike many other industrial processes, bioprocessing involves complex living cells, making measurements and measurement-based predictions of bioprocess performance a challenging task. The extreme complexity and the resulting poor predictability of the behavior of biological systems are reasons why the pharmaceutical industry is still lagging behind other industries in implementing 4.0 production concepts [1,3].

Important support for the implementation of Bioprocessing 4.0 production concepts in the pharmaceutical industry was the FDA’s guidance on process analytical technology (PAT) published in the year 2004. The PAT guidance aimed to reduce process variability, thereby increasing the quality, safety, and efficiency of drug manufacturing. The guidance defined PAT as a “system for designing, analyzing, and controlling manufacturing through timely measurements (i.e., during processing) of critical quality and performance attributes of raw and in-process materials and processes, with the goal of ensuring final product quality” [4]. According to this definition, it can be deduced that in addition to automated in-process control, the collection of critical quality attributes of the used raw materials is also of central importance. For this purpose, Securecell developed the Lucullus® Media Kitchen tool. It supports a digitally assisted process preparation phase employing e.g., raw material management with barcoding, electronic protocols, or user-guided media lot creation.

The i2BPLab (intelligent and integrated bioprocessing laboratory) at Zurich University of Applied Science (ZHAW) is funded by the Swiss government's Innosuisse Impulse Program (project number 41524.1 IP-ENG [5]) and aims to demonstrate how upstream unit operations in R&D labs and manufacturing plants can be successfully digitalized and automated to achieve paperless and more efficient workflows, embracing Bioprocessing 4.0 cornerstones (Figure 1A). The i2BPLab infrastructure is complemented by Securecell’s bioprocess digitalization and automation tools, Lucullus® and Numera®. With the modular sampling system Numera®, bioreactor sampling, sample processing, and transfer to an autosampler module for sample storage or to various 3rd party analyzers are completely automated. Lucullus® as overarching software monitors and controls all processes in up- and downstream over the complete seed train, including the bioreactor systems, the automated sampling system Numera® and integrated 3rd party analyzers.

However, Lucullus® is not only limited to basic SCADA (supervisory control and data acquisition) functionalities. Over the years, Lucullus® was extended by the Planning tool for bioprocess scheduling and preparation in terms of equipment assignments and sample planning, a Media Kitchen tool for raw material and recipe management, as well as guided media production, and the Graphic tool for advanced evaluation of process data and report creation. Thus, Lucullus® holds extensive and unique pre- and post-process running functionality.

Benefits of a digitalized pre-process phase

In many laboratories preparation of different consumables such as media, feeds, supplements, and buffers for upstream or downstream bioprocess applications is performed according to a printout protocol in a highly manual fashion. This entails a huge documentation and management effort of the warehouse, and in GMP (Good Manufacturing Practice) usually requires the four-eyes principle. Moreover, the manual preparation is error-prone, lot traceability is challenging, and lot quality variations of critical material attributes are even more difficult to identify. The aforementioned challenges of manual process preparation are effectively addressed by the Lucullus® Media Kitchen tool, digitalizing the process preparation phase to easily trace, document, and understand what happened before the bioprocess was started.


The value of advanced analytics & hybrid models

Formalized process knowledge ranging from simple trends through interdependencies of process variables to process models and systems of models provide the structural framework of DataHow’s technology. Within this backbone DataHow embeds cutting-edge machine learning solutions to unveil and integrate the versatile information hidden in the big process data. This hybridization yields powerful process models which are tailored to the specific needs at different stages of process development and manufacturing. Such models require less experiments for training compared to conventional DoE-based approaches and have a much stronger capability of extracting new process knowledge and finding optimal process operation routes. The ultimate goal of such models is to support decision-making and process automation. In particular, cloud solutions can help the model to compare the current process with all available process history, inside and, when possible, outside the company. At the same time, machine learning tools can be trained not only to predict the process but also to take decisions (the so-called reinforced learning), for instance for process control and global optimization purposes.

Process flow Media Kitchen

The Media Kitchen tool has to be configured which is normally done by a Securecell employee according to customer requirements. The configuration includes the registration of integrated devices (e.g., pH meter, scales, label printer), the definition of possible actions (e.g., add material, start mixing, start incubating), the generation of a supplier catalog (e.g., Sigma-Aldrich, Thermo Fischer, Gibco), the listing of chemical groups (e.g., alcohols, ethers, thiols) just to mention a few. A proper configuration is important for the precise classification of the raw materials and the establishment of electronic protocols organized in action rows. After the configuration, all the raw materials are registered (Figure 1B), material details, supplier details, and lot number specified, and the respective barcodes printed. Also registered devices are labeled with a barcode. To create a new media lot, first, the device (e.g., scale) is scanned with a barcode scanner. Then, the raw material component is scanned, and the correct amount weighted. Lucullus® automatically takes the value of the scale and adds it to the respective action row of the protocol. If the weight-in value is not in a user-defined range, it will be rejected to avoid mistakes. Following this procedure, a new media lot can be prepared step-by-step just by scanning the barcodes and weighing raw material components (Figure 1C). The prepared consumables are then assigned to the respective bioprocess (Figure 1D). Following this procedure, full bioprocess information from the initial raw material lots to the final product is ensured.

Use-case: digitalized media management at ZHAW

The Lucullus® Media Kitchen tool is extensively used by members of the bioprocess technology group in the i2BPLab at ZHAW. Over 200 different consumables are registered in the digital warehouse and around 85 different protocols for media components or growth media are actively applied. At ZHAW, the Media Kitchen is composed of a balance, a pH meter, a label printer, and a barcode scanner (Figures 2). With as few as four devices and the software Lucullus®, media management is fully digitalized.

The Lucullus® Media Kitchen database is integrated together with upstream processing applications and analyzers via the local network in a central standalone Lucullus® installation. Each media, feed, supplement, and buffer produced can be assigned to the respective upstream processing application or analyzer with which it was used ensuring complete lot traceability.


Figure 3: "New Lot" window with specifications.

Below the workflow of a guided LB-media lot creation using the Lucullus® Media Kitchen is described using screenshots, kindly provided by the members of the bioprocess technology group at ZHAW. From the media recipe database (Figure 3), listing all the historically produced media, feeds, supplements, and buffers, the corresponding consumable to be prepared (here LB-Fortified) is selected.

In the "New Lot" window (Figure 4), the lot name (here 220714_LB_Fortified_hatr) and amount (here 5 kg) need to be specified and the “Free Lot” checkbox unchecked. The checkbox can be activated, if the predefined concentration ranges of a raw material component in the electronic protocol is altered to perform DoE (Design of Experiment) for e.g., growth media optimization. Thus, the user is not forced to create several electronic protocols for the same consumable just differing in the concentration of one raw material component.

Thereafter, in the "New Lot" window, the “Check Availability” field is selected, and the "Available Ingredient Amounts" window opens (Figure 5). The availability of all raw material components that are needed to prepare the LB-medium is listed. If a raw material component is marked red, it is not available in a sufficient amount to produce the specified 5 kg of LB-medium.

Figure 5: "Available Ingredient Amounts" window indicates missing "peptone from casein" for the preparation of 5 kg LB-Fortified.

If all raw material components are available, the user can navigate to the guided media lot creation by clicking . The "Electronic Protocol" window opens (Figure 6) which is organized in action rows. Simply, by using the barcode scanner and weighing the correct amounts, the LB-medium is prepared step-by-step. If the actual raw material amount is outside a predefined range, the user cannot proceed to the next step in order to ensure maximum quality.

Before a process is started in the execution monitor, the prepared medium is assigned to the respective process to conveniently track the raw material footprint in the final product (Figure 7). In retrospect in the Evaluation tool, the user can search for all processes that were run with this lot of LB-Fortified medium.

Compared to other industries, only a few R&D labs and manufacturing plants already comply with 4.0 production concepts. The i2BPLab at ZHAW showcases such a completely digitalized and automated innovation laboratory. Securecell’s bioprocess digitalization and automation tools Lucullus® and Numera® are integral parts of the i2BPLab infrastructure, contributing to paperless and more efficient workflows.

The use-case at ZHAW demonstrates the Lucullus® Media Kitchen as a valuable tool to completely digitalize the process preparation phase ensuring full data integrity from the initial raw material to the final product and thus closing existing gaps in the value chain of biotechnological products. Additionally, the Media Kitchen tool also facilitates media optimization and thus process optimization by conveniently tracking the raw material footprint in the final product. In the end, critical material attributes that influence critical quality attributes have to be understood and controlled and supplier/lot issues identified to ensure quality.

Key Findings:
- Bioprocess digitalization: full data integrity, computer-readable format, improved workflow
- Streamlined bioprocess optimization
- Record of raw material footprint in the final product
