See the Related Links for "AEM.ASM.org: journal article on pseudomonas aeruginosa in crude oil degradation" to the bottom for the answer.
Abstract of article from NIH.gov (see link to the left):
"The potential biodegradation of crude oil was assessed based on the development of a fermentative process with a strain of Pseudomonas aeruginosa which produced 15.4 g/L rhamnolipids when cultured in a basal mineral medium using glycerol as a sole carbon source. However, neither cell growth nor rhamnolipid production was observed in the comparative culture system using crude oil as the sole carbon source instead. As rhamnolipid, an effective biosurfactant, has been reported to stimulate the biodegradation of hydrocarbons, 1 g/L glycerol or 0.22 g/L rhamnolipid was initially added into the medium to facilitate the biodegradation of crude oil. In both situations, more than 58% of crude oil was degraded and further converted into accumulated cell biomass and rhamnolipids. These results suggest that Pseudomonas aeruginosa could degrade most of crude oil with direct or indirect addition of rhamnolipid. And this conclusion was further supported by another adsorption experiment, where the adsorption capacity of crude oil by killed cell biomass was negligible in comparison with the biologic activities of live cell biomass."

Where is energy stored in an unlit candle?
the energy stored in an unlit candle is chemical potential energy, and it is stored in the bonds between the atoms in the hydrocarbons (wax) that make up the candle.
Which of the following may be a benefit of the overproduction of proteins?
One potential benefit of overproduction of proteins is that it can provide a surplus of a particular protein that is needed for a specific cellular process or function. This can ensure that there is enough of the protein available to carry out its intended role effectively. Additionally, overproduction can serve as a protective mechanism to compensate for potential loss or degradation of proteins.
Why is alcohol flammable?
Alcohol is the name given to a group of molecules called hydrocarbons. The alcohol present in drinks is ethanol. These hydrocarbons contain many chemical bonds and in turn a large energy potential. When the the alcohol is lit by a another source of energy (lighter) the bonds break rapidly releasing energy in the form of heat. Fossil fuels such as petroleum and coal contain hydrocarbons. As a point of interest internal combustion engines do not efficiently harvest the energy contained in fossil fuels and hence pollute the atmosphere. In a similar comparison our bodies extract energy from similar bonds such as carbohydrates (sugars) and lipids (fats).
What is potential step from 1 potential to o potential?
1 potential to o potential
The electrical charge of an inactive neuron is known as?
Potential, ok well we all know it's a potential, but which one? Is it Action Potential, Synaptic Potential or Membrane Potential. Just saying Potential isn't saying much?
Any real or potential condition that can cause mission degradation injury illness or death to personnel or damage to or loss of equipment or property is a?
Hazard
How does Ubiquitin tagging fit into the process of protein degradation?
Ubiquitin tagging allows the 19S subunit of the 26S proteasome to recognize the potential protein substrate.
A hazard is defined as?
Any real or potential condition that can cause mission degradation; injury, illness, or death to personnel; or damage to or loss of equipment or property.
What is any real or potential condition that can cause injury illness or death to personnel - damage to or loss of equipment or property - degradation of mission capability - or impact on a mission?
This is one definition of a hazard.It is "any real or potential condition that can cause injury, illness, or death to personnel; damage to or loss of equipment or property; degradation of mission capability or impact to mission accomplishment; or damage to the environment."
Is fossil fuels kinetic or potential energy?
I would actually describe the energy as chemical, as the energy is being used to hold the chemical bonds of the hydrocarbons together. But it is certainly not kinetic, so give these two choices the answer is potential. It is potential energy waiting for a chemical reaction.

Why hydrocarbons are used as fuel?
There are two reasons : 1) Higher calorific value 2) Large chain hydrocarbons have high impurities and when broken into smaller chain compounds their volumetric rate increases. So for the same mass we get a higher volume and this translates into greater profitability.

How does the size of and number of atoms contained in a hydrocarbon affect its properties?
As the base number of carbon atoms in a simple hydrocarbon increases, the higher the potential energy contained in the compound. More complex hydrocarbons can also have shifting melting and boiling ranges.
What is hydrocarbons?
A molecule that contains hydrogen and carbon, but no other elements is a hydrocarbon molecule. An example of a hydrocarbon molecule is methane, with the formula CH4

What is an example of potential stored energy?
If a rock is balanced on the edge of a cliff if has gravitational potential energy because it could gain kinetic energy (movement) which no input of energy. as the rock fall the gravitational potential energy is turned into kinetic energy as it runs out of height to speed up in. Batteries have electrical potential energy because they can give an electrical current by using up their power. Hydrocarbons like wood, fat and oil have chemical potential energy because they can give off heat and light energy when they are chemically reacted (combusted/burned). A spring has elastic potential energy because it can go from not moving to moving without being pushed or thrown, it converts the tension in it's fibres into kinetic energy while trying to return to it's original shape. I hope this answer is useful to you.
