AI simulates human cognitive abilities, enabling machines to make autonomous decisions based on data analysis. It encompasses supervised, unsupervised, semi-supervised, and reinforcement learning methods, crucial for optimizing bioprocesses by improving productivity and ensuring regulatory compliance. Robots, integral to automation, perform repetitive or hazardous tasks with precision and efficiency, contributing to enhanced data acquisition and process reliability.
AI-Based Tools and Systems in Filamentous Fungi Cultivation:
In filamentous fungi cultivation, leveraging AI-driven tools and systems is crucial for optimizing bioprocesses by maximizing product yields and minimizing costs and environmental impacts. Automation through AI facilitates real-time monitoring and control of critical parameters like pH, temperature, and nutrient levels. Smart sensors enable in situ sampling, providing continuous data without disrupting sterility. Image analysis tools automate biomass measurement and fungal morphology assessment, enhancing efficiency and accuracy. Robotic systems handle complex tasks such as nutrient addition and sampling. Smart bioreactors integrate AI for advanced process control, improving scalability and reproducibility. These technologies promise to revolutionize fungal bioprocessing by ensuring consistent, high-quality production outcomes.
Automated Estimation of Water Activity in Solid-State Fermentation:
In SSF, where fungi thrive with minimal free water, accurately estimating water activity (aw) is crucial for optimizing growth conditions. A method was devised using MATLAB to estimate surface condensation, a proxy for aw, based on digital image analysis of fungal biomass and water droplets. This non-destructive approach offers a cost-effective means to monitor and control fermentation parameters, ensuring optimal fungal growth and metabolic activity. Such advancements enhance process efficiency and mitigate contamination risks, underscoring the role of AI-driven tools in advancing SSF bioprocessing.
Research Needs and Future Directions in Fungi-Based Bioprocesses:
Future advancements in fungi-based bioprocesses should focus on integrating AI and automation to enhance real-time data collection, optimize the production of organic acids, enzymes, and pharmaceuticals, and improve operational efficiency. Developing multi-parameter smart sensors to streamline monitoring and control is critical, reducing installation complexity and contamination risks. Additionally, advancements in automated morphology control, online biomass estimation, and quality control are essential for scaling up bioprocesses effectively. Addressing these challenges will support sustainable food production and meet rising global demands amidst climate and resource constraints, driving towards more efficient and cost-effective bioprocessing solutions.
