What is the optimum pH and temperature for growth of Propionibacterium shermanii?
The optimum pH for growth of Propionibacterium shermanii is typically around pH 6.5-7.0. For temperature, it grows best at around 30-37°C. These conditions are favorable for the growth and metabolism of Propionibacterium shermanii in various applications such as food fermentation.
What is p shermanii?
During cheese-making the bacteria are added to certain cheeses such as Emmental (also known as Swiss) and Leerdammer, and when warmed bubbles of carbon dioxide form in the cheese. These bubbles then become the distinctive holes (or eyes) in the finished product. This bacteria can also get you dizzy and sick for a couple of weeks or 2.
What kind of bacteria causes acne?
The primary bacteria that causes acne is Propionibacterium acnes. It is a normal part of the skin microbiota but can contribute to acne when it multiplies excessively in hair follicles, leading to inflammation and the formation of pimples.
Which microorganism species is most well adapted to life on the skin?
The most well-adapted microorganism species to life on the skin are bacteria, particularly Staphylococcus epidermidis and Propionibacterium acnes. These species have evolved to thrive in the skin's unique environment, contributing to the skin's natural microbiome and helping to maintain skin health.
What microorganisms live below the skin surface?
Various microorganisms can live below the skin surface, including bacteria such as Staphylococcus epidermidis and Propionibacterium acnes. These organisms are part of the normal skin flora and play a role in maintaining skin health. However, disruptions in the skin microbiome can lead to skin conditions such as acne or infections.
What is the optimum pH and temperature for growth of Propionibacterium shermanii?

What type of bacteria causes acne?
PROPIONIBACTERIUM
Medium for growing propionibacterium?
Propionibacterium can be grown in a medium like Brain Heart Infusion (BHI) broth or agar, which provides nutrients such as amino acids, vitamins, and minerals for its growth. Additionally, specialized media like Reinforced Clostridial Medium (RCM) or Sodium Propionate Agar can also be used to cultivate Propionibacterium species.

What are the virulence factors for propionibacterium acnes?
The primary virulence factors of propionibacterium acnes are lipase (which helps to break down the yucky oils/lipids on our face), hyaluronidase (which is an enzyme that breaks down the connective tissues and increases the permeability of connective tissues), neuraminidase, proteases, inflammatory mediators, and other enzymes.
What hydrolysis test would a positive test result be expected for the etiologic agent of acne Propionibacterium acnes?
Triglycerides hydrolysis test because this bacterium feeds on fatty acids.
Propionibacterium?
Gram + pleomorphic rods; Diphtheroids 2) Aerotolerant anaerobes, i.e, obligate fermenters - only produce ATP via SLP. 3) Inhabit anaerobic microenvironments of the skin (hair follicles). 4) Produce propionic acid as 1^ fermentation end product. 5) Ferment lactic acid; extract residual energy from a waste product of other bacteria. 6) Propionibacterium acnes - Acne (p. 523)
Are some diseases caused by bacteria?
Yes, there are many. A few are : Actinomyces which cause respiratory diseases and cavities, Propionibacterium which can cause acne and Bortadella which causes pertussis better known as whooping cough.
What kind of bacteria causes acne?
The primary bacteria that causes acne is Propionibacterium acnes. It is a normal part of the skin microbiota but can contribute to acne when it multiplies excessively in hair follicles, leading to inflammation and the formation of pimples.
What is the vector of acne?
one of the major causes of acne is Propionibacterium acne bacteri,although it is a normal bacteria found in skin but it the vector which in certain circumstances can cause blockage of the follicle on the skin surface and result in acne formation
