    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.
