Which organism might harvest energy from iron?
Certain bacteria, known as iron-reducing bacteria, have the ability to harvest energy from iron by using it as an electron donor for their metabolic processes. These bacteria can convert iron from its oxidized form to a reduced form, releasing energy in the process. This ability allows them to thrive in environments where iron is abundant, such as in certain soil and aquatic environments.
What group are unicellular prokaryotic organisms that live in harsh environments such as volcanic hot springs brine pools and anaerobic black organic mud in?
Archaea are unicellular prokaryotic organisms that are known to inhabit harsh environments such as volcanic hot springs, brine pools, and anaerobic black organic mud. They are known for their ability to survive in extreme conditions that many other organisms cannot tolerate.
Do bacteria have the ability to perform photosynthesis?
No, bacteria do not have the ability to perform photosynthesis.
What are the two main groups of prokaryotes?
The two main groups of prokaryotes are bacteria and archaea. Bacteria are widespread and diverse, while archaea are known for their ability to thrive in extreme environments. Both groups lack a cell nucleus and membrane-bound organelles.
What similarities do archaebacteria and bacteria share?
Archaebacteria and bacteria are both single-celled microorganisms that lack a nucleus and other membrane-bound organelles. They also share similarities in their genetic material, cell structure, and ability to survive in various environments.
Is Serratia marcescens an obligate aerobe or a facultative anaerobe?
Serratia marcescens is a facultative anaerobe, meaning it can grow in the presence or absence of oxygen. While it can use oxygen for respiration, it also has the ability to ferment carbohydrates in anaerobic conditions when oxygen is not available.
Is E aerogenes aerobic?
E. Coli can be but only in oxygen free conditions. Normally it is aerobic.
Is micrococcus luteus a facultative anaerobe?
No Micrococcus luteus is aerobic organism, Staphylococcus aureus is often mistaken for Micrococcus luteus but its main difference is that it is a Facultative anaerobe
Is staphylococcus aureus obligate aerobe?
Streptococcus pyogenes is a facultative anaerobic gram-positive bacterium. It is not a obligate aerobe. It consists of long chains of round cells. The bacteria is non-motile, meaning it does not move.
Is B megaterium a faculative anarobe?
Bacillus megaterium is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. This bacterium has the ability to switch between aerobic and anaerobic metabolism depending on the availability of oxygen in its environment.

Why is cyanide harmless to some bacteria?
Because some bacteria are anaerobic (do not need oxygen to survive). In humans and other aerobic organisms, cyanide prevents cells from respiring (turning oxygen and glucose into energy) so they run out of energy and die. Anaerobic bacteria produce energy in other ways, so cyanide doesn't harm them. (:
What group of bacteria are known as ancient bacteria?
Archaebacteria, also known as archaea, are a group of bacteria that are considered ancient because they are phylogenetically distinct from other bacteria and have unique characteristics. They are known for their ability to thrive in extreme environments, such as hot springs, acidic environments, and deep-sea hydrothermal vents.
Do plants like methane?
Most plants do not benefit from methane. In fact, high concentrations of methane can be toxic to plants as it interferes with their ability to take up oxygen and essential nutrients. Methane is primarily used by certain bacteria and archaea in anaerobic environments.
What is a facilitative anaerobe?
A facilitative anaerobe is a type of microorganism that can grow in the presence or absence of oxygen but prefers oxygen when it is available. These organisms have the ability to switch between aerobic and anaerobic metabolism depending on the environmental conditions.
What are facultative pathogens?
Facultative pathogens are bacteria that can live either as harmless commensals or as potential pathogens, depending on the conditions in the host. They have the ability to switch between modes of living based on the host's immune system and other factors. Examples include Staphylococcus aureus and Escherichia coli.
Name bacteria which are used in ethanol production?
Saccharomyces cerevisiae and Zymomonas mobilis are two common bacteria used in ethanol production. They possess the ability to ferment sugars into ethanol through anaerobic processes.
