Synechocystis physiological parameters

Counting cells, counting molecules

Overview

Background

Estimating physiological parameters is necessary for building meaningful models that can help us to rationally design our consortium. In addition production stability can be assessed by estimating this parameters over a long period of time give

Aim

We aim to use different cultivation strategies to Characterize growth and production rates of carbon producing Synechocystis strains their stability. .

Approach

We have used turbidostat cultivation methods to determine the stability of the physiological parameters

Results

We have demonstrated the instability of classical engineering strategies. As shown in figure 1 the strain SAA023 lose the ability to produce lactate after 300 hours of continuous culture.
