Just Enough Oxygen: Cultivating Fastidious Pathogens in Microaerobic Workstations

A sustainable microaerophilic environment for incubation and manipulation of microbiological samples is crucial to culturing Campylobacter jejuni, Helicobacter pylori, and other fastidious pathogens. The ability to provide a customisable low level of oxygen for pathogens that can’t be cultivated successfully in ambient air or under strictly anaerobic conditions is a prerequisite for culturing these microorganisms.

The M series microaerobic workstations by Don Whitley Scientific, provide precise gas control of up to four gasses for a customisable low oxygen environment that doesn’t require expensive custom gas mixes. The entire temperature-controlled interior of the chamber serves as the work and incubation area, ensuring that growing cultures are never exposed to ambient conditions. Though the robust MACS VA workstations are still being used in many laboratories, we have invested considerable resources into developing the next generation microaerobic workstation, the M series, with increased atmospheric precision and a touchscreen interface. A range of sizes with capacities from ~600 to ~1400 plates will accommodate every workflow and space requirement. Options such as data logging, internal HEPA filtration, gas pressure monitoring and automated humidity control provide protection and accountability.


Clinical and research institutions worldwide are using our microaerophilic workstations to cultivate fastidious microorganisms with confidence.

Researchers are taking advantage of the stable microaerobic atmosphere generated in our workstations to investigate the expression of H. pylori toxin in gastric pathology, integration of selected genes onto the C. jejuni chromosome, spectroscopic differentiation of foodborne Campylobacter strains and the epidemiology of antibiotic-resistance in Campylobacter in cattle.
