Creative Document on the Importance of Pseudomonas Lundensis Essay
Pseudomonas lundensis The species of
Pseudomonas that I chose
Pseudomonas lundensis is a gram negative, rod shaped bacteria that are motile with one polar flagella that propels it forward. The optimal temperature for
P. lundensis is 25°C but its temperature range is from 0°C to 33°C. One third of
P. lundensis strains can also grow at 37°C (optimal human body temperature). The colonies on nutrient agar will be smooth, circular and lack pigment but a green tinge may sometimes be seen.
P. lundensis cannot grow at a pH of 4.5.
P. lundensis was isolated and discovered living on refrigerated meat, other cases found on …show more content…
P. lundensis is important is because it is the most common microorganism to cause the spoiling of meat producing a slim or bad odor (G. Molin, 1986), this is important to know in the food industry. The third reason that
lundensis is important because it is one of the dominant microorganisms that causes spoilage in refrigerated seafood(Y.H. 2005), this is important to know for working in the food industry or for home cooking.
The most interesting fact I learned about by species is the fact that is a common and dominant microorganism that causes spoilage in meats, seafoods and dairy products. And the fact that it has the ability to grow in your fridge. This is important for consumers to remember because many people often think of their refrigerator as clean and safe however, there are organisms that can survive and thrive in a refrigerated environment.
A bacteria that could be living in your refrigerator
Pseudomonas lundensis is a gramnegative, rod shaped
Pseudomonas bacteria that is motile by one polar flagella.
P. lundensis produces the fluorescent pigment pyoverdine.
Pyoverdine is a water soluble pigment that produces a green yellow color under UV light. Pyoverdine is best seen when streaked on King’s B agar which has proteose peptones & glycerol which enhances pigment production.
