Methane-consuming Bacteria More specifically, methanotrophs are a unique type of bacteria capable of using methane as their only source of energy. They are often found in environments like peatlands, rice paddies, hot springs and mud pots.

Bacteria that grow only in the absence of oxygen, such as Clostridium, Bacteroides, and the methane-producing archaea (methanogens), are called obligate anaerobes because their energy-generating metabolic processes are not coupled with the consumption of oxygen.

Bacteria that metabolize methane (methanotrophs) are found in soil and aquatic environments with little to no oxygen. In these anaerobic habitats, the bacteria play a critical role as carbon recyclers; they convert methane (CH4) into more useful molecules that they and other organisms depend on.

The aerobic methane oxidizing bacteria or methanotrophs are a group of bacteria that grow on methane as a sole source of carbon and energy. They are a subset of the methylotrophic bacteria which can grow on a number of different one carbon compounds (Lidstrom, 2006).

Methanogenesis is an anaerobic respiration that generates methane as the final product of metabolism. In aerobic respiration, organic matter such as glucose is oxidized to CO2, and O2 is reduced to H2O. In contrast, during hydrogenotrophic methanogenesis, H2 is oxidized to H+, and CO2 is reduced to CH4.

Methanotrophs (sometimes called methanophiles) are prokaryotes that metabolize methane as their source of carbon and energy. They can be either bacteria or archaea and can grow aerobically or anaerobically, and require single-carbon compounds to survive.

Methane is building in the atmosphere at an increasing rate, creating a thick blanket that warms the earth. One way to slow this warming is to destroy methane. By breaking the bonds holding it together, it won’t be able to trap heat.

Methane provides a great environmental benefit, producing more heat and light energy by mass than other hydrocarbon, or fossil fuel, including coal and gasoline refined from oil, while producing significantly less carbon dioxide and other pollutants that contribute to smog and unhealthy air.

Now a team from Washington State University has engineered a small reactor that inexpensively breaks water and methane into carbon monoxide and hydrogen. Because piping methane gas from remote areas is expensive, energy companies burn off about one-third of the gas they produce.

Methane has a large effect but for a relatively brief period, having an estimated mean half-life of 9.1 years in the atmosphere, whereas carbon dioxide is currently given an estimated mean lifetime of over 100 years.

approximately 9 years

Because methane can be captured from landfills, it can be burned to produce electricity, heat buildings, or power garbage trucks. Capturing methane before it gets into the atmosphere also helps reduce the effects of climate change.

Methane is extremely flammable and will easily cause explosions. It can leak unnoticed into structures and spaces, and a tiny spark can ignite the undetected gas. Explosions from methane gas are extremely strong, and the damage is devastating.

The most common cause of sewer gas smells in your house is a leak in your plumbing. You’ll want to prevent even small leaks to avoid major plumbing repair costs. Sewer gas smells could be coming from your pipes either because they weren’t installed properly or were damaged.

Generally, the first step is to use a plumbing camera to detect the exact location of the leak. Your plumber may also use dye or steam to make the leak appear above ground. Once the cause is determined, your plumber may suggest hydro-jetting your pipe, replacing the sewer line, or another solution.

A septic odor in your home usually means there’s a plumbing problem, but not all issues require calling a plumber. The floor drain trap in your basement could be dried out, allowing septic tank gases to vent back into your house. Periodically filling the drain traps with water will correct the problem.

Sewer Bacteria As bacteria begin to reproduce and multiply inside your toilet bowl, they can cause a foul smell that remains even after you clean your toilet. Fortunately, getting rid of tiny microorganisms from the sewer is fairly simple. The flush valve is located inside your toilet tank. Then, flush your toilet.
