Answer:
TIME: a single bacterium can multiply to over two million in just seven hours.
WARMTH: the 'danger zone' temperatures at which bacteria grow best are between 5 Celsius and 63 Celsius.
FOOD: like any other living things, germs need food to grow.
WATER: Bacteria need moisture to grow.

Answer:
Optimal temperature and food-source.
Explanation:
Of course, different bacteria have different needs, but in general they strive in temperatures starting from 30-40ºC, and when it comes to thermophiles or hyperthermophiles, the ideal temperature is 60º C+ or 80º C+ respectively.
Nutrients are also important during binary fission (the reproduction of bacteria), but since bacteria can find nutrients basically everywhere, this factor doesn't really have "conditions".
