What does pH measure? it measuses the hydrogen Osmotic Pressure - Changes in osmotic concentrations in the environment may affect microbial cells - Hypotonic solution Does water enter or leave cell? Enter Osmotic lysis may occur if cell wall Carbon - All organisms require carbon Why? - Carbon source for - Heterotrophs $$=$$ organic molecales - Autotrophs $$=$$ througl carbon aioxide Nitrogen, Sulfur, Phosphorus - Nitrogen - Used to make and - sources of nitrogen Most bacteria decompose proteins Some bacteria use $${\mathrm{NH}}_{+}$$or $${\mathrm{NO}}_{?}$$ A few bacteri fixation (ex- Trace Elements - Minerals that are required in small amounts - Ex-iron, zinc, copper, molybdenum Oxygen Concentration - Some microbes require 02 to grow Why? - Aerobes vs. anaerobes Aives requigg. - Phosphorus - In ATH, , oNA , ENA , and - PO43- is a source of phosphorus
