Optimizing and Scaling an Automated Sampling System to Improve Quantification of CO2 Utilization in Cultures of Engineered Cyanobacteria

Sustainability icon, disabled. A green leaf.

Measuring changes in concentration within a dynamic system can be accomplished with a simple Arduino powered system. Currently, the system is utilizedĀ in cyanobacteria CO2 fixation experiments, where the fixation rates of multiple cultures can be measured simultaneously. The system employs solenoids in parallel and can be applied for n number of outlet streams, all connected to one large manifold which feeds to some gas concentration probe. In the future, the system can be modified to fit other simple dynamic gas systems such as carbon sequestering systems.
