Could serratia marcescens and kocuria rhizophila be identified using broth?
Yes, Serratia marcescens and Kocuria rhizophila can be identified using broth culture methods. These bacteria can be grown in specific broth media that support their growth and allow for observation of their characteristic features, such as color changes or turbidity. Subsequent biochemical tests or molecular methods can then confirm their identities based on the characteristics observed in the broth culture.
When the bacterium Serratia marcescens is grown on a sterile culture medium in a Petra dish at 30C the bacterial colonies are cream colored. When this same bacterium is cultured under identical con?
When Serratia marcescens is grown at 30°C, it typically produces cream-colored colonies due to the absence of certain pigments. However, if the temperature is altered or if the growth conditions change (such as increased temperature or different nutrients), the bacterium may express different pigments, such as red or pink, leading to a change in colony color. This variation is often due to the regulation of genes responsible for pigment production, which can be influenced by environmental factors.
What can you do once you have cultured bacteria?
A person can not see what is in the culture until it is grown and then tests are run. An incubator is where they are grown in dishes or tubes.
What nourishes bacteria?
moisture noruishes bacteria. the wet damp atmosphere is an ideal conditions for bacteria to grow. the temperature also has a rapid effect on bacteria, the warmer the climate, the more easily bacteria is grown.
How does autotrophic bacteria get food?
They are grown on medium that contains the nutrient that they cannot synthesize

If streaking for isolated colonies was done with Serratia Marcescens what is the difference between pigmentation between cells grown at 25 and 37 degrees celsius?
Serratia marcescens incubated at 37 degrees Celsius will have almost a clear pigmentation. However, when S. marcescens is incubated at 25 degrees Celsius it will produce a very distinct red color.

Can serratia marcescens grow in mannitol salt agar?
No it doesn't because it doesn't ferment mannitol. P. mirabilis can actually grow on a MAC agar, but it is colorless. I actually had this lab in Micro260 today.An MSA agar has 7% high salt concentration and provides growth for S. aureus bacteria turning it yellow/gold. An MSA agar is selective for osmotolerant bacteria meaning for bacteria that can grow in different salt concentrations, and it's differential because it can ferment mannitol.
What difference was seen in the serratia colonies grown at 25 degrees and 37 degrees celsius?
Serratia colonies grown at 37 degrees Celsius showed faster growth and larger colony size compared to those grown at 25 degrees Celsius. The color of the colonies may also differ, with colonies grown at 37 degrees Celsius often appearing darker or more pigmented.
Does penicillin have bacteria?
it is grown from bacteria
What was US Navy Operation Sea-Spray in 1950's?
Operation Sea-Spray was a U.S. Navy secret operation / experiment that used burst balloons to disperse the bacterium Serratia marcescens over the city of San Francisco on Sept. 26-27, 1950.Until that time, S. marcescens was thought to be non-pathogenic (incapable of causing disease), and had been used as a simulant in biological warfare tests. Until Sea-Spray, there wasn't any indication that it was dangerous or infectious. That was proven to be wrong after the dispersal test.Within a few days of the dispersal, several serious and rare cases of urinary tract infections evolved (with one fatality), and there was a marked increase in the number of pneumonia cases in the area as well.Since 1950, the S. marcescens has grown and become more resistant to antibiotics.
What flowers cannot bloom?
Sterile ones, like most of the corn grown today (in the US).
Why can bacteria be grown in a petri-dish but not possible for viruses?
Viruses need host cells to replicate and this cannot be done by growing them like bacteria cells are grown.
Are 'Indian Blanket' sunflower seeds edible?
As the flowers are grown for decoration and are sterile, they don't make great eating.
Is bacteria green?
Bacteria is not necessarily green. In fact, bacteria cultures grown on a plate often show up as white splotches.
What can you do once you have cultured bacteria?
A person can not see what is in the culture until it is grown and then tests are run. An incubator is where they are grown in dishes or tubes.
