Atmosphere-Generation System Promotes Anaerobic Growth

A new system consisting of air-activated, atmosphere-generating sachets and sealed containers is designed for the culture of anaerobic organisms. No catalysts are needed and no water is required.

Successful culture of anaerobic and microaerophilic organisms relies on achieving the right atmospheric conditions. Oxoid (Basingstoke, UK) has developed AnaeroGen, an atmosphere-generation system, which reacts rapidly to produce an atmosphere of < 1% oxygen supplemented with carbon dioxide within 30 minutes, facilitating the culture of fastidious and obligate anaerobes. Oxoid CampyGen produces a microaerobic atmosphere ideal for the growth of Campylobacter species, while Oxoid CO2Gen achieves an enriched aerobic environment that improves the growth of fastidious organisms such as Haemophilus and Neisseria species.

These new Oxoid products quickly create the required gaseous conditions without generating hydrogen, safely facilitating the prompt identification of cultures by maximizing recovery and colony size. The system is quick and easy to use without any requirement for investment in capital equipment. Use of non-hazardous chemicals also means that there are no hazardous material transport fees to pay.

Plates can be sealed, cultured, and transported in the specifically designed AnaeroGen. Oxoid's AnaeroGen, CampyGen, and CO2Gen are also available in compact formats that facilitate the culturing of small batches of plates in transparent pouches.
