    Streptomyces venezuelae is a developing host for synthetic biology and metabolic engineering. To accelerate the understanding of this host and access secondary metabolism enzymes, the authors have characterized a high-yield S. venezuelae in vitro transcription-translation (TX-TL) system for synthetic biology. The system utilizes 3-phosphoglyceric acid (3-PGA) to regenerate energy and has been shown to synthesize up to 1.3 µM of sfGFP (under batch synthesis) and a range of enzymes from the oxytetracycline biosynthesis pathway.

    The pH is an important parameter for the efficiency of enzymatic reactions. Small volume flow reactors, also known as microfluidic reactors, can be used to optimise enzymatic reactions at low cost. Therefore, being able to measure the pH in a microfluidic reactor is very important. In this contribution the authors demonstrate that the measurement of pH in such a reactor is possible by integrating pH sensors at multiple locations. These sensors were used to measure the pH in two enzymatic reactions and it was shown that the pH could be adjusted to remain within boundaries ideal for the enzymes.
