alcoholic fermentation and lactic acid fermentation
Gas bubbles are produced by lactose fermenters as a byproduct of fermentation. Some lactose fermenters may produce more gas due to differences in the types and abundance of gas-producing enzymes they possess, while others may not produce as much gas due to variations in their metabolic pathways or the presence of alternative pathways that do not result in gas production. Additionally, environmental factors such as pH, temperature, and the presence of other nutrients can also influence the amount of gas produced during lactose fermentation.
Neutral red serves as a pH indicator in MacConkey agar, which is a selective and differential culture medium for gram-negative bacteria. It helps to distinguish lactose-fermenting bacteria, such as Escherichia coli, from non-lactose fermenters. When lactose is fermented, acidic byproducts lower the pH, causing the neutral red to turn pink, indicating the presence of lactose fermenters. In contrast, non-lactose fermenters remain colorless or take on the color of the medium.
Salmonella and Shigella agar (SS agar) is both selective and differential. It is selective because it inhibits the growth of most gram-positive bacteria and non-enteric gram-negative bacteria, allowing for the isolation of Salmonella and Shigella species. Additionally, it is differential as it contains indicators that differentiate between lactose fermenters and non-fermenters, with lactose fermenters producing pink colonies and Salmonella and Shigella typically forming colorless colonies.
The protease enzyme is used in some washing powders. The protease enzyme usually comes from bacteria like Bacillus licheniformis or Bacillus subtilis and can be produced in fermenters which hold many litres of culture medium and bacteria.
Yes, removing eosin Y from methylene blue agar (EMB) would alter the medium's sensitivity and specificity. Eosin Y acts as a pH indicator that helps differentiate lactose fermenters, such as E. coli, from non-fermenters by producing a color change. Without eosin Y, the visual distinction between colonies would be reduced, potentially leading to misidentification of lactose fermenters and affecting the medium's overall effectiveness in isolating and identifying specific bacteria.
Aerobic fermentation and anaerobic fermentation are two main types.

Humans are not foregut or hindgut fermenters. These are special adaptations that occur in herbivores (such as horses and cows).
All ruminants (cows, sheep, goats, etc.) and kangaroos are foregut fermenters.
Tower fermenters are simple in design and easy to construct. They consist of a long cylindrical vessel with an inlet at the bottom, an exhaust at the top, and a jacket to control temperature. They do not require agitation hence there are no shafts, impellers or blades.Tower fermenters are used for continuous fermentation of beer, yeast and SCP.
No, they are different things.
A bioreactor is a vessel used for a wide range of biological processes, while a fermenter is specifically designed for fermentation processes. Bioreactors are more versatile and can be used for various types of reactions, while fermenters are specialized for microbial fermentation. Bioreactors typically have more advanced control systems and monitoring capabilities compared to fermenters.

Yes. Hind-gut fermentors are psuedo-ruminants.
Fermentation in hindgut fermenters occurs in the cecum and colon, where bacterial fermentation processes break down plant fiber and produce volatile fatty acids that can be absorbed by the animal for energy.
