Oxygen Requirements 1. Aerobes 2. Anaerobes 3. Facultative 4. Microaerophilic

Agar Stabs & Agar Shakes 1. Liquify 6 NA Deeps in boiling water 2. Boil for 10 minutes to drive out dissolved oxygen 3. Allow 3 NA Deeps to cool and solidify Agar Stabs 4. Temper 3 NA Deeps in water bath at 55 degrees C Agar Shakes

Agar Stabs 1. Single stab with Inoculating needle – straight down, straight back up 1. Micrococcus luteus 2. Staphylococcus epidermidis 3. Clostridium sporogenes Clostridium rubrum Clostridium butrycum

Agar Shakes 1. Inoculate with Inoculating Loop - “shake” test tube so bacteria are equally distributed 1. Micrococcus luteus 2. Staphylococcus epidermidis 3. Clostridium sporogenes Clostridium rubrum Clostridium butrycum
