Microbiology for Pharmacy Technicians: Chemical and Physical Factors Affecting Microbial Growth

This presentation on Microbiology for Pharmacy Technicians covers the chemical and physical factors that affect microbial growth, including warmth, moisture, pH, and oxygen level. It also explains the uses of growth media and the microbial growth curve. References are included.

•Budding
•Cell budding is the type of asexual reproduction occur in the
single celled organisms, examples of bacteria which reproduce
by the budding are Caulobacter, Hyphonmicrobium and Stella
spp..

Section 2: Chemical and physical
factors that affect the growth of
microorganisms•The most basic chemical and physical factors which impact the microbial growth are
warmth, moisture, pH and oxygen level. Below is the brief explanation of all these chemical
and physical factors affecting microbial growth.
•Chemical factors which effects the growth of microorganisms
• Ph-
●Osmotic pressure –
Physical factors affect the growth of microorganisms
●Water
●Oxygen
●Carbon
