Citrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to pyruvate and CO2.

If an organism is able to convert the sodium citrate in simmons citrate agar to pyruvate what are some possible reasons why an organism might ferment rather than metabolize it oxidatively in the Krebs?

Is natural selection the process by which factors in an organism's competition determine whether or not the organism will be able to produce offspring?
yes it is
What idea says that a type of organism that is better able to survive in its environment than another type of organism will produce more offspring and become predominant?
Natural selection.
What is the difference between sodium and sodium oxide electrical conductivity?
Sodium metal, in both its solid and liquid states, is a conductor. This is due to the delocalised 'sea' of electrons present in metallic bonded substances, which are able to carry and transfer current. Sodium oxide in its solid state is not conductive. This is because of its ionic bonded structure, in which sodium and oxygen ions are arranged in a continuous 3D structure, where they are fixed in place as an ionic lattice. However, in its molten state (or aqueous) the Na+ and O2- ions are free to move around, hence being able to carry current and thus conduct
Which of these would most likely live in a temperate forest biome?
an organism that needs lots of water to survive is able to prevent water from evaporating

Where can you get sodium citrate in the UK?
Sodium citrate is a food additive. It is commonly used in drinks to regulate acidity - and as an emulsifier in cheese manufacture. You should be able to order it from any chemical manufacturer. However - it could be expensive if you only need a small quantity (lesss than a kilo for example).
How does klebsiella pneumoniae use citrate as a source of carbon?
Klebsiella pneumoniae is a member of the Enterobacteriaceae family and is able to anaerobically use citrate as a source of Carbon because the citrate contains citritase, an enzyme that initiates a catabolic process. The carbonate and nitrogen of the citrate is broken down into acetate and oxalacetic acid, and then pyruvic acid and carbon dioxide. These products reacts with the ammonia (nitrogen and hydrogen) and sodium hydrogen carbonate compounds of the Citrate. The K. pneumoniaeaccumulates the alkalines and create a basic pH. (I think?)
Does pseudomonas aeruginosa have a positive result for citrate utilization?
The color changes from the slant's original green to blue, indicationg that the species is able to utilize citrate as a carbon source. Thus, it is POSITIVE

Is bacillus cereus positive for methyl red?
Most bacteria in Tribe V are able to utilize Citrate, with the exception of Hafnia and Pantoea (+/-). The 2 most common Klebsiella (oxytoca and pneumoniae), can utilize citrate, so should be citrate positive.
What type of organism whose occur in photosynthesis?
Autotrophs. Plants and algae's as well as phytoplankton which are able to convert sunlight and CO2 to glucose energy by mechanism of the chloroplast.
