pH and osmotic pressure as limiting factors

most organism prefer a pH near

6-7 neutral

bacterial are _ than fungi

less acid tolerant

acidophilic bacteria

bacteria can grow under acidic conditions

marin organisims are

alkalophilic bc of pH of water being >8

Fungi (and many bacteria) are protected from lysis due to low osmotic pressure by

their cell walls

most bacteria are sensitive to

high osmotic pressure

bacteria growth is inhibited by environments containing

more than a few dissolves materials

bacteria are sensitive to

lower water availability

water is available when

materials dont have hydrogen bonds

more dissolved molecules means

less amount of water available
