Bill Gates Invests in Green Crude

there are a number of big-time, serious investment firms that have looked at Sapphire Energy, looked at their proposal, looked at their data, and decided it was worth investing over $100 million so far based on that data.

Methane -- Yes I am, and that is the object of the anoxia. Methane is a product of bacteria that consume organic material, that and production of CO2 are the result of the water having enough oxygen to support the microorganisms that would normally consume the biological matter.

reference

Methanogens are bacteria that produce methane gas. They are very anaerobic (oxygen is toxic to them) and sensitive to pH.

From your source (scroll all the way down, and it's the first sentence in the last section):

My bold.

Breaking Down a Dead Body:

Saprobic bacteria invade every inch of the dead body, and begin eating and digesting its tissues. There are many types of bacteria that live inside the body. These bacteria are the first to begin the process of decomposition after an organism dies. The initial bacteria start physical break-down of muscles. They tear apart the muscle tissue into individual protein strands. More saprobic bacteria soon move in to help break down the organic matter. Because there are so many bacteria in the soil (about 2 billion in 1 gram of fertile garden soil), decomposition occurs more rapidly after a body is buried. Decay that occurs underground or underwater is known as anaerobic decomposition. One specific type of anaerobic decay that is very important to the carbon cycle is biogas production. This process has three steps: hydrolysis, acidification, and methane formation.
Hydrolysis -- Splitting a Protein:

Proteins are broken down by an enzyme called protease that is secreted by fermentative bacteria. This enzyme separates proteins (polypeptides) into amino acids (peptides). It accomplishes this depolymerization through a process known as hydrolysis. In hydrolysis, a water molecule is inserted between the two amino acids that are bonded together. This breaks the bond between them by capping the free reactive ends with the H and the OH. The protein,therefore, is broken down from long chains into its individual molecules, amino acids.

Acidification -- From Serine to Acetic Acid:

In the next step, a new group of bacteria called acetogens take over. These bacteria decompose amino acids into acetic acid, hydrogen gas, nitrogen gas, and carbon dioxide gas. To do this, they need oxygen which they obtain from O2 dissolved in the body's fluids or bound in the body's structure. While acetogens are anaerobic bacteria, oxygen is not as poisonous to them as to some other anaerobes. The chemical reaction that occurs when acetogens decompose amino acids is:

2C3H7NO3 O2 ---> 2HC2H3O2 3H2 N2 2CO2
serine (amino acid) oxygen ---> acetic acid hydrogen nitrogen carbon dioxide

Because acetogens produce acid, the pH of the organic matter falls to about 4 or 5. This low pH is toxic to the next group of bacteria, the methanogens. As the acetogens die out, however, the pH rises and methanogens become more predominant.

Biogas Formation -- From Acetic Acid to Methane:

Methanogens are bacteria that produce methane gas. They are very anaerobic (oxygen is toxic to them) and sensitive to pH. These bacteria are also very biologically primitive. Methanogens have, therefore, been a part of the carbon cycle for a long time. They combine the acetic acid made by acetogens with hydrogen gas, and carbon dioxide to produce methane gas, water, and carbon dioxide, according to the following equation:
HC2H3O2 4H2 CO2 --> 2CH4 2H2O CO2
acetic acid hydrogen gas carbon dioxide --> methane water carbon dioxide
