What is a proteus experiment?
The Proteus Experiment is an online blog. The author discusses many different issues and topics. Some of the topics include food, fashion, and celebrities.
Does proteus vulgaris produce h2s?
Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar. Yes, it does. It is Indole Production positive, H2S positive, and Motility positive. This can all be seen using SIM agar.
Explain the function of phenol red in the urea broth medium?
phenol red act as the pH indicator. As the substrate urea is split into products, the presence of ammonia caused alkaline environment that cause the phenol red to turn to deep pink. Useful to test Proteus vulgaris.
Why is p vulgaris positive in the H2S test?
P. vulgaris is H2S positive because it obtains its energy by oxidizing organic compounds or molecular hydrogen H2 while reducing sulfates to sulfides,especially to hydrogen sulfide.[1] In a sense, they "breathe" sulfate rather than oxygen. Sulfate-reducing bacteria can be traced back to 3 billion years ago and are considered to be among the oldest forms of bacteria.Many bacteria reduce small amounts of sulfates in order to synthesize sulfur-containing cell components; this is known as assimilatory sulfate reduction. By contrast, the sulfate-reducing bacteria reduce sulfate in large amounts to obtain energy and expel the resulting sulfides as waste; this is known as dissimilatory sulfate reduction. They are anaerobes which use sulfate as the terminal electron acceptor of their electron transport chain.Most sulfate-reducing bacteria can also reduce other oxidized inorganic sulfur compounds, such as sulfite, thiosulfate, or elemental sulfur (see sulfur-reducing bacteria
Which organism can change the shape?
Several organisms have the remarkable ability to change their shape. This ability is often referred to as "shape-shifting" or "morphological plasticity." Here are some examples of organisms from various taxonomic groups that can change their shape: Amoebae (e.g., Amoeba proteus): Amoebae are single-celled protists known for their shape-changing abilities, enabled by pseudopodia, temporary cytoplasmic extensions they use for movement and capturing food. Cephalopods (e.g., octopuses, squids, and cuttlefish): Cephalopods are highly intelligent marine animals. They have soft bodies and can rapidly alter the texture, color, and shape of their skin to blend in with their surroundings and communicate with other individuals. Flatworms (e.g., planarians): Flatworms are simple, bilaterally symmetrical animals that possess regenerative abilities. They can alter their body shape and regenerate lost body parts. Tardigrades (water bears): Tardigrades are micro-animals known for their extreme resilience. They can undergo a process called cryptobiosis, where they lose almost all water content and shrink into a tun-like shape, surviving extreme conditions. Slime molds (e.g., Physarum polycephalum): Slime molds are unique organisms that can change their shape to optimize nutrient absorption. They exhibit complex behavior despite being single-celled during some stages of their life cycle. Sea cucumbers: Sea cucumbers are echinoderms that can change their body shape dramatically by contracting their body wall muscles or expelling their internal organs as a defense mechanism. Bacteria (e.g., Escherichia coli): Some bacteria, like Escherichia coli, can change shape based on environmental conditions. For example, they can shift from a rod-like shape to a spherical shape under certain stresses. Hydra: Hydras are small, simple, freshwater animals capable of changing their body shape during feeding and locomotion. Proteus anguinus (olm or cave salamander): The olm is a blind, aquatic salamander known for its adaptability and ability to change its body shape based on the environment and feeding habits. Flowering plants (e.g., Mimosa pudica, Venus flytrap): Some plants can undergo rapid shape changes in response to stimuli. For instance, the sensitive plant (Mimosa pudica) folds its leaves when touched, and the Venus flytrap (Dionaea muscipula) snaps its trap shut when triggered by an insect. These examples highlight the diversity of organisms that possess the ability to change their shape, either as a part of their natural behavior or in response to environmental cues. The ability to alter shape plays a crucial role in their survival, feeding strategies, and defense mechanisms.

Explain how the urease test is useful for identifying members of the genus proteus?
Genus proteus is know for their fast hydrolysis of urea into ammonia. In presence of proteus the agar slant quickly turns pink (positve) while known proteus would be yellowish. The pink color is a sign of alkaline presence and the increase of pH (7-8.5) and phenol red is the pH color indicator. http://www.microbelibrary.org/Laboratory%20Diagnostics/details.asp?id=457&Lang=
