aerobic bacteria use oxygen based respiration, anaerobic bacteria use either nonoxygen based respiration (e.g. nitrogen, sulfur) or fermentation.
Facultative anaerobic bacteria can switch between using aerobic and anaerobic metabolism depending on oxygen availability. Obligate anaerobic bacteria cannot survive in the presence of oxygen and rely only on anaerobic metabolism, while obligate aerobic bacteria require oxygen for survival and use aerobic metabolism exclusively.

Monera bacteria can be aerobic (requiring oxygen for metabolism) or anaerobic (able to thrive without oxygen). Some species are capable of both aerobic and anaerobic metabolism, depending on the environment they are in.
No, anaerobic bacteria do not require oxidase because they do not use oxygen for their metabolism. Oxidase is an enzyme used by aerobic bacteria to catalyze the transfer of electrons to oxygen during respiration. Anaerobic bacteria have alternative pathways for energy generation in the absence of oxygen.

Bacteria that do not require aerobic respiration are known as anaerobic bacteria. These bacteria can survive and grow in the absence of oxygen by using alternative electron acceptors in anaerobic pathways such as fermentation or anaerobic respiration. Examples of anaerobic bacteria include Clostridium and Methanogens.

Salmonella bacteria are anaerobic.
Facultative anaerobic bacteria can survive and grow in both oxygen-rich (aerobic) and oxygen-poor (anaerobic) environments, while obligate aerobes require oxygen to survive and obligate anaerobes cannot survive in the presence of oxygen.
