Bdellovibrio bacteriovorus HD100 is an obligate predator that preys upon a wide variety of Gram negative bacteria. The biphasic growth cycle of Bdellovibrio includes a free-swimming attack phase and an intraperiplasmic growth phase, where the predator replicates its DNA and grows using the prey as a source of nutrients, finally dividing into individual cells (Sockett, 2009). Due to its obligatory predatory lifestyle, manipulation of Bdellovibrio requires two-member culturing techniques using selected prey microorganisms (Lambert et al., 2003). In this protocol, we describe a detailed workflow to grow and quantify B. bacteriovorus HD100 and its predatory ability, to easily carry out these laborious and time-consuming techniques.
