Question

Which of the following is a major growth-limiting micronutrient that influences microbial growth?
A) iron
B) water
C) vitamin K
D) sugar

Accepted Answer

Iron is essential for microbial growth and is involved in many cellular processes. It is a major growth-limiting micronutrient, as iron availability is often limiting in many environments. Water, vitamin K, and sugar are important for microbial growth, but they are not growth-limiting micronutrients.
