What is the Ultimate energy source for the bacteria?
The ultimate energy source for bacteria is organic matter, such as sugars, amino acids, and fats. Bacteria convert these organic compounds into energy through processes like fermentation, respiration, or photosynthesis, depending on the type of bacteria and available environmental conditions.
What is the final electron acceptor in fermentation?
In fermentation, the final electron acceptor is an organic molecule rather than an inorganic molecule like oxygen in aerobic respiration. This can vary depending on the type of fermentation, but common examples include pyruvate, acetaldehyde, or organic acids like lactic acid or ethanol.
What molecule is needed for aerobic respiration but not for fermentation?
Oxygen is needed for aerobic respiration but not for fermentation. Aerobic respiration utilizes oxygen as the final electron acceptor in the electron transport chain to produce ATP, while fermentation produces ATP without using oxygen by fermenting sugars into organic molecules like ethanol or lactic acid.
Why does pseudomonas give negative reactions on all the fermentations?
Pseudomonas bacteria typically give negative reactions in fermentation tests because they are mostly aerobic bacteria and do not ferment carbohydrates like other bacteria. Instead, they carry out oxidative metabolism using organic compounds as their energy source. As a result, they do not produce the byproducts associated with fermentation reactions, leading to negative results in fermentation tests.
Two different types of fermentation?
Two different types of fermentation are lactic acid fermentation and alcoholic fermentation. Lactic acid fermentation is used by bacteria and some animal cells to produce energy without oxygen, resulting in the production of lactic acid. Alcoholic fermentation is used by yeast and some bacteria to produce energy without oxygen, resulting in the production of ethanol and carbon dioxide.
What type of cell respiration occurs when an organic molecule accepts hydrogen atoms?
Anaerobic respiration occurs when an organic molecule accepts hydrogen atoms in the absence of oxygen. This process typically involves glycolysis followed by fermentation to produce ATP in the absence of oxygen.
How do bacteria produce carbon monoxide?
Bacteria can produce carbon monoxide through the breakdown of organic compounds, such as sugars, in a process called fermentation. This fermentation process can release carbon monoxide as a byproduct.
What is carbohydrate fermentation?
Carbohydrate fermentation is a metabolic process in which microorganisms break down carbohydrates into organic acids, gases, and alcohols in the absence of oxygen. This process is commonly used in laboratory settings to differentiate and identify bacteria based on their ability to ferment specific carbohydrates.

Does spirilla bacteria get energy?
Yes, spirilla bacteria can get energy through various methods such as photosynthesis, chemosynthesis, or by breaking down organic matter through fermentation or respiration.
Does Fermentation involve an electron transport chain?
No, fermentation does not involve an electron transport chain. Instead, it is a metabolic process that generates ATP without the use of oxygen by using an organic molecule as the final electron acceptor.

What kind of molecule is an organic molecule?
Derivatives of CARBON are termed as organic compounds or organic molecules
Is an oxygen molecule an organic molecule?
No, an oxygen molecule (O2) is not considered an organic molecule. Organic molecules contain carbon atoms, while oxygen molecules do not contain carbon. Organic molecules are the building blocks of life and are typically associated with living organisms.
