Aseptic technique.

This chapter describes common laboratory procedures that can reduce the risk of culture contaminations (sepsis), collectively referred as "aseptic technique." Two major strategies of aseptic work are described: using a Bunsen burner and a laminar flow hood. Both methods are presented in the form of general protocols applicable to a variety of laboratory tasks such as pipetting and dispensing aliquots, preparing growth media, and inoculating, passaging, and spreading microorganisms on petri dishes.
