Biology of Anaerobic Bacteria and Predominant Propagation Practices

7/20/2017


Abstract: Culturing anaerobes in the laboratory can be challenging. Due to the copious growth requirements and the plethora of anaerobic organisms, knowing the optimal conditions for your anaerobic organism is essential. In this webinar, we will present the various methods to achieve successful growth conditions for a wide variety of anaerobes. We will consider topics such as common anaerobic gas mixtures, media selection, and obtaining anaerobic conditions in the lab. Taking into account individual laboratory constraints, we will also discuss several propagation methods available today. Using specific examples from the ATCC collection, we will demonstrate these techniques.

Key Points:

  • There are numerous types of anaerobic bacteria with various atmospheric and nutritional requirements from clinical gut and wound isolates to environmental extremophiles.
  • Creating and maintaining anaerobic atmospheric and nutritional conditions are critical for the successful growth of anaerobic bacteria.
  • The propagation of anaerobic bacteria has evolved throughout the years. The discovery of new isolates has brought about the need for more robust culturing technology.
