Microbial Genetics Why the bacterium Treponema pallidum is difficult to culture? Because it requires a great deal of water to reproduce Because it lacks the genes needed for TCA cycle and oxidative phosphorylation Because it requires extremely low temperature at which water freezes Because it is unable to use carbohydrates as an energy source Because it requires a great deal of water to reproduce Because it lacks the genes needed for TCA cycle and oxidative phosphorylation Because it requires extremely low temperature at which water freezes Because it is unable to use carbohydrates as an energy source ANSWER DOWNLOAD EXAMIANS APP
