    Study Notes

    Microbial Resistance

    • Spores demonstrate the highest resistance to environmental stresses and chemicals.
    • Vegetative cells show moderate resistance.

    Microbial Forms

    • Viruses are the least resistant microbial form, as they are highly sensitive to environmental factors and chemicals.
    • Lethal mutations are characterized by permanent loss of reproductive capability.

    Microbial Death

    • Microbial death is hard to detect due to the inability to distinguish between dormant and dead cells, as well as the presence of viable but non-culturable cells.
