Tips on automatic feeding procedures

In the evolving landscape of biotechnology, the automation of bioprocesses represents a significant leap towards efficiency, precision, and scalability. Automatic feeding procedures, particularly for cultures requiring a steady influx of carbon sources, have become indispensable. This blog post delves into the sophisticated world of automatic feeding, utilizing the innovative capabilities of the Eggsbee Bioreactor and Eggsbee Online platform.

The Role of Carbon Sources in Bioprocesses

Carbon sources like glucose or sucrose are the lifeblood of microbial and cell cultures, fueling growth and product formation. The controlled delivery of these nutrients is crucial, as it influences the metabolic rate, biomass yield, and overall process efficiency. However, manual nutrient addition is labor-intensive and prone to human error, underscoring the need for an automated solution.

Introducing the Eggsbee Ecosystem for Automatic Feeding

The Eggsbee Bioreactor, a flagship product of Dynacyte Biosciences, is engineered for precision and ease of use, making it an ideal candidate for automating feed procedures. Coupled with the Eggsbee Online platform, it offers a seamless, automated feeding process that can be monitored and adjusted in real-time.

Step 1: Setting Up the Feed Bottle

The process begins with preparing a feed bottle containing the desired carbon source at the required concentration. This feed bottle is connected to the Eggsbee Bioreactor via the Pump Module, which is responsible for the controlled delivery of the feed into the bioreactor vessel.

Step 2: Sensor Integration

The Eggsbee Bioreactor is equipped with an array of sensors, including those for measuring optical density (OD), pH, dissolved oxygen (DO), and more. These sensors play a critical role in monitoring the culture's condition and determining the optimal times for nutrient addition.

Step 3: Configuring Eggsbee Online for Automatic Feeding

Eggsbee Online, the bioreactor’s cloud-based management platform, is where the magic of automation takes place. Users can set up automatic feedback loops based on real-time data collected from the bioreactor's sensors. For instance, a common strategy is to initiate feeding when the OD reaches a certain threshold, indicating that the culture is ready for more nutrients.

Creating a Feedback Loop

  1. Define Trigger Conditions: Within Eggsbee Online, users specify the conditions that will trigger the feed pump. This could be based on OD readings, pH shifts, or a combination of parameters, customized to the specific needs of the culture.

  2. Feed Schedule and Rate: The platform allows for the precise scheduling of feed intervals and the rate at which the feed is added. This granularity ensures that the culture receives nutrients at the optimal rate for growth without the risk of overfeeding or nutrient depletion.

  3. Monitoring and Adjustments: The real-time data feed from the bioreactor's sensors into Eggsbee Online enables continuous monitoring of the process. Users can make on-the-fly adjustments to the feeding strategy based on observed performance, enhancing the process's adaptability and outcome.

Benefits of Automatic Feeding with the Eggsbee Ecosystem

  • Precision and Control: Automated feeding eliminates the guesswork and variability associated with manual nutrient addition, leading to more consistent and reliable bioprocess outcomes.

  • Time Efficiency: By automating the feeding process, researchers and bioprocess engineers can save significant time, allowing them to focus on more critical aspects of their work.

  • Scalability: The Eggsbee ecosystem simplifies the process of scaling bioprocesses from lab to production scale by maintaining precise control over nutrient addition across different scales.

  • Data-Driven Decisions: The integration of real-time sensor data with automatic feeding procedures empowers users to make informed decisions, optimizing their processes based on actual performance metrics.

In conclusion, the automatic feeding capabilities of the Eggsbee Bioreactor and Eggsbee Online platform represent a significant advancement in bioprocess automation. By leveraging the power of real-time sensor data and cloud-based control, users can achieve unparalleled precision, efficiency, and scalability in their bioprocesses, paving the way for the next generation of biotechnological innovation.
