Staphylococcus Epidermidis does return a gram positive result on the citrate lab test. Gram stains will produce these results on slides.
How do bacteria make lactic acid?

Why are gram positive bacteria more heat resistant than gram negative bacteria?
Gram positive bacteria contain more peptidoglycan than gram negative bacteria which is the substance responsible for the increased strength of gram positive bacterias cell walls therefore making them more resistant to heat. Gram negative do contain peptidoglycan but much, much less
Does bacteria produce toxins?
Yes. Bacteria do produce toxins. Usually gram positive bacteria produce exo-toxins and gram negative bacteria produce endo-toxins.
Explain why a false positive reaction result can be obtained with Koser's citrate medium?
If carbon sources, or nutrients, are carried over into the citrate medium, it will result in a false positive. To avoid this, dilute the inoculum in saline before inoculating the citrate medium.
What else can produce their own nutrients besides plants?
a few bacteria and even then they need to metabolize an element to extract the energy traped in it
Why do you smell more from perspiration?
Due to fatty compounds presence within the sweat coming from the apocrine gland, bacteria metabolize it to produce various compounds which produce the known sweat odor.
Zymomonas mobilis which type of bacteria?
its a gram negative anaerobic bacteria used to ferment glucose and produce ethanol.
What type of bacteria is typhoid causing bacteria?
The are gram negative bacillus shaped bacteria. They are facultative anaerobic bacteria. They ferment the glucose to produce acid and gas. They ferment the sulfur containing amino acids to produce H2S gas. They do not ferment the lactose.
Would you expect Clostridium to produce catalase?
No. Clostridium bacteria will display a negative result in a catalase test indicating that bacteria do not produce catalase, therefore preventing oxygen accumulation.
What is the main purpose of fermentation reactions?

What Transgenic bacteria can be used to produce?
Genetically modified bacteria can be used to produce. This is a transgenic bacteria.
How does plaque cause tooth decay?
Plaque is various types of bacteria in large quantities. These bacteria metabolize (eat) carbohydrates (sugars) that are in the mouth. The bacteria then produce acids which erode the enamel of the teeth, resulting in tooth decay.
