Study Notes
Temperature Tolerance in Microbes
- Psychrophilic microbes are known as 'cold-loving microbes'.
Temperature Ranges in Microbes
- Thermophiles: 50°C to 110°C (high-temperature loving microbes)
Classification of Microbes by Temperature
- The primary factor used to classify microbes into different groups is their preferred temperature range.
Importance of Understanding Microbial Growth Conditions
- The primary reason for understanding microbial growth conditions is to control the growth and survival of microorganisms.
Microbial Colonies
- Colonies in microbiology refer to visible clusters of microbial cells that have grown on a solid medium, such as agar, as a result of cells multiplying from a single microbial cell.
