(a and b) Enhanced mycobacterial enrichment is performed in the PMEU Spectrion® (Samplion Oy, Siilinjärvi, Finland) cultivation and detection unit. The incoming and outgoing gases are sterile filtered. The gases are produced specifically for laboratory use. Bacterial concentrations are indicated by IR, UV or optical light sensors, which measure the change in the amount of transmitted light.

(a and b) Growth curves on M. marinum from PMEU Spectrion® analysis. The culture with gas flow above (a), and the reference culture without gas flow below (b). In the former one, the onset of growth was recorded in less than 12h.

Growth of Mycobacterium marinum ATCC 927 [8]. Values for the colony forming units (cfu) after 5 days of cultivation in the PMEU Spectrion® and subsequent plating on M7H9 broth medium with 1.25% agar. Cultures 1 and 2 in enrichment syringes represented growth with gas flow, and cultures 3 and 4 were grown without gas flow. This figure illustrates the situation with full-grown cultures. The resulting higher cell densities in the PMEU cultures with gas bubbles are in line with the observations with the microaerobic Campylobacter sp. [10].
