Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.
Why do bacteria only grow at certain temperatures?
- The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
- Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
- An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

An Environmental Activist is a broad term for someone who is actively engaged in fighting for the environment. It could even be said that both environmental lawyers and environmental journalists are environmental activists in their own rights. However, someone could still be an activist without being a journalist or a lawyer, and this activist may be involved in fundraising, petitioning, and actively protesting. Environmental journalism is quite self explanatory; to report though written and/or verbal media to spread information on issues pertaining to the environment. An environmental lawyer fights legal battles to ensure dangerous actions are prevented or held accountable, and may also impact future legislation regarding environmental management.
Hey there,
There are many ways waves can shape Earth's surface. For example, the waves can constantly brush up against a rocky ledge or cliff, and it can shape the cliff. It can change it's shape and/or form and can break away the rock or land. The waves can also bang against the rock, making it loose and the rock shapes itself by falling off or apart. This is otherwise known as erosion.
Best Of Luck,
