Microbial growth and control
8 important questions on Microbial growth and control
Wat heeft glycaantetrapeptide nodig om over het cytoplasmamembraan getransporteerd te worden?
What is a divisome and what are its components?
MincD and minE inhibit ftsZ ring formation.
5 types of cell division?
- simple budding
- budding from hyphea
- cell division from stalked organisms
- polar growth without differentation
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
3 components of peptidoglycan biosynthesis?
- Glycolases: insterts cell wall precursors+ catalyzes glycosidic bond formation
-Autolysins: makes a small opening starting at FtsZ ring
4 phases in the growth curve of a population of cells grown in a closed system?
- Exponential phase: growth at max rate
- stationary phase: growth rate is zero
- death phase: lysis + death
4 groups of microbes classified by temperature growth.
- mesophile: midrange temp
- thermophile: high temp
- hyperthermophile: very high temp
3 groups of mo's based on pH.
- Alkaliphiles: grow best at high pH (+9)
- Neutrophiles: grow best at pH between 6-9
4 groups of mo's based on solute concentration?
- Halotolerant: grow best in absense of solute, but can also grow in presense.
- Halophiles: solute percentage between 5-10% required.
- extreme halophiles: requires solute percentage of 15-30%
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
