pH and Microbial Growth Introduction: Each organism has an optimum environment for growth‚ which includes pH level. Organisms that grow at near neutral pH levels are called neutrophiles. Those that grow best in acidic pH values are called acidophiles. Others‚ yet‚ grow best in alkaline pH values and are called alkaliphiles. In this lab‚ each group was assigned an organism‚ which was then used to inoculate 6 different pH levels. Materials and Methods: Followed lab procedure 29‚ “pH and
