Bacteria that prefer to grow at room temperature at low pH are: Mesophilic acidophiles Microaerophilic alkalophiles Psycrophilic neutraphiles Thermophilic acidophiles
Microbial Physiology
Microbial physiology is the branch of microbiology that is associated with studying the physiology of fungi, bacteria, and viruses. It is an important field of science concerning functional genomics and metabolic engineering.
Chemotaxis
The organism’s movement in a particular direction as a response to certain chemicals that are available in the environment is defined as chemotaxis. In brief, it can be defined as the occurrence of an organism’s movement in response to a certain chemical stimulus.
Bacterial growth is influenced by many factors such as temperature, oxygen requirements, pH, source of nutrition, pressure, salinity etc. Different bacteria have a different range in which these factors are necessary for their growth. The amount at which the growth of bacteria is maximum is termed as the optimal condition. For example the temperature at which the growth of bacteria is maximum is termed as its optimum temperature.
