a nice warm substance
the 4 conditions needed for yeast to grow are: 1. Warmth 2. Moisture 3. Food 4. Time
Yeast like to grow in warm and moist conditions.
Yeast require energy to grow and divide its cells, therefore yeast grows best in sugar solution.
Most bacteria will grow in dark, moist, warm areas with a neutral PH balance (ph7, water, sweat, most foods) and a source of food for the bacteria, such as sugars, and protein. All bacteria need to grow in conditions such as this is time. (And not very long, either. 4 hours on average)
Yeast needs warmth, food and moisture to grow while bacteria needs warmth, food , correct ph,oxygen, and time to grow. Moulds need warm, moist conditions and viruses need time and opportunity for the conditions to be right for them to thrive.
they need heat or sunlight
The yeast organisms are waiting for the proper conditions to grow. They are already in the dog's ears. They are in your ears, too. They are everywhere.
sun and rain
sunlight, water and air .....
Yeast cells grow well in environments that provide optimal conditions for their metabolism, including a temperature range of 25-30°C (77-86°F), pH level between 4 and 7, and a carbon source such as glucose. They also prefer oxygen-rich environments but can still grow in oxygen-depleted conditions through fermentation.
no
Yeast metabolism is the way yeast breathes or grow.
