Methylophilaceae

Methylophilaceae is a family of bacteria in the order Methylophilales, within the class Betaproteobacteria. This family of bacteria is characterized by their ability to metabolize methylamine, a simple one-carbon compound.

Taxonomy

The family Methylophilaceae currently consists of the following genera:

• Methylophilus
• Methylotenera
• Methylovorus

Metabolism

Members of the Methylophilaceae are facultative methylotrophs, meaning they can use a variety of carbon sources for growth, but preferentially use methylated compounds when available. They are able to oxidize methylamine to formaldehyde, which is then assimilated into biomass via the serine pathway.

Ecology

Methylophilaceae are found in a wide range of environments, including soil, freshwater, and marine systems. They play a key role in the global carbon cycle by consuming methylated compounds, which are often overlooked as significant carbon sources.

Health implications

While Methylophilaceae are not typically pathogenic, they have been found in the human gut microbiome. Their role in human health is not yet fully understood, but they may contribute to the metabolism of dietary methylamines.

Research

Research on Methylophilaceae has focused on their unique metabolic capabilities and their role in the environment. They are also of interest for biotechnological applications, such as the production of single-cell protein from methanol.
