Localizes the synthesis of new cell wall to specific locations along the long axis of a rod-shaped cell during growth, which allows new cell walls to form at several points along the cell rather than from a single location at your FtsZ site (encircled) outward.

This phase can last for minutes up to hours.

Require nutrition of bacteria

pH Acidophiles have

Require osmolarity of Bacteria

This is the highest temperature that permits a microbe's growth and metabolism.

Required pH of Bacteria

Is an anchor that connects the FtsZ ring to the cytoplasmic membrane and stabilizes it (for stabilization)

Example of Obligate aerobe

Optimum temp - between 20 to 30°C but grows well at lower temp

Grows between pH 8 and 11.5

Penicillin-binding protein

Psychrophile are usually found in

Example of Microaerophile

Optimum temp - 50 to 60°C

Organisms that are able to grow in high sugar environments.

In addition, bacterial spores are produced in this phase by bacteria like Bacillus and Clostridium.

Grows between pH 5.5 and 8

Optimum temp - between 20 to 30°C; Grows best at 30 to 37°C

Temperature requirement of Bacteria

Under anaerobes, (-) O2 not required and not utilized

Is the process of forming a cross wall between 2 daughter cells

Temperature hyperthermophile can tolerate

Example of Neutrophiles

Example of Micronutrients

Example of Obligate Anaerobe

Example of Aerotolerant

pH Neutrophiles have

Microorganisms that inhabit marine environments that have a NaCl requirement and typically grow optimally at the water activity of seawater.

pH Alkalophiles have

Example of Faculltative aerobe

Is a vibrio-shaped species of Proteobacteria, that produces a shape-determining protein called crescentin in addition to MreB.

Grows between pH 0 and 5.5 (pH < 5.5)

This phase is characterized by vigorous metabolic activity of cells yet no division is observed or happening, hence zero (0) growth rate.

Example of Organic nutrients

Example of Acidophiles

Example of Alkalophiles

Oxygen requirement for bacteria

An organism in an enclosed vessel cannot grow exponentially indefinitely, suggesting that the bacterial growth curve presented above can only occur in bacteria given the provided setting of

Required in large quantities; play principal roles in cell structures and metabolism.

(-) O2 not required and its presence is harmful or lethal to the bacteria

Required in small amounts; involved in enzyme function and maintenance of protein structure.

Require oxygen to grow and replicate

Temperature psychrotrophs can tolerate

FtsA is a protein related to

Example of Mesophile

This phase is characterized by rapid cell division.

Is the solvent of life and an important factor affecting the growth of microorganisms

Example of Macronutrients

This is the lowest temperature that permits a microbe's growth and metabolism.

Contain carbon and hydrogen atoms and are usually the products of living things.

Microorganisms that can tolerate some level of dissolved solutes but grow best in the absence of the added solute.

Usually found in environments like arctic and antarctic regions

Required level is less than 0.2 atm

Optimum temp - Can grow well above the temperature of boiling water which exists under high pressure in the depths of the ocean

This is the temperature that promotes the fastest rate of growth and metabolism of a microbe.

(-)/(+) O2 not required but they grow better with O2

Is a protein related to the Actin, an important cytoskeletal protein in eukaryotes

Most organisms are categorize under this temperature

Example of Hyperthermophile

Organisms that are able to grow in very dry environments.

Phases of bacterial growth curve

This is also when toxic products cause growth to slow until the number of new cells produced balances or equal the number of cells that died (new cells = # of cells that died).

Division of bacterial cells occurs mainly through

Example of Thermophile

Forms a helix of filaments around the inside of the cell wall, just below the cytoplasmic membrane

In this phase, the growth rate is negative.

Temperature thermophile can tolerate

Important cause of food spoilage

β-Lactam antibiotics, which are bactericidal agents that interrupt bacterial cell-wall formation, are most effective in this phase.

Example of Psychrophile

Optimum temp - between -5 to 15° C

The number of your microbial cells doubles in a constant time interval.

This phase is characterized by a marked decline in the number of viable bacteria.

Atom or molecule that contains a combination of atoms other than carbon and hydrogen

Long process of binary fission

Process of binary fission

Oxygen is harmful to them or they only use little oxygen

(-) O2 required is only at levels lower than atmospheric pressure

Shape of Caulobacter crescentus

Temperature psychrophile can tolerate

This phase is characterized by zero (0) growth rate due to lack of nutrition by depletion.

(+) O2 required

The protein Caulobacter crescentus produce

Temperature that is optimal for many free living forms
