Hyphomicrobium

Definition

Hyphomicrobium is a genus of Proteobacteria known for its unique budding reproduction and methylotrophic metabolism. These bacteria are commonly found in aquatic environments and soil.

5 Must Know Facts For Your Next Test

1. Hyphomicrobium species reproduce through a process called budding, where a new cell forms from the parent cell.
2. They are methylotrophs, meaning they can utilize one-carbon compounds like methanol as their carbon source.
3. Commonly found in both freshwater and marine environments, as well as soil and wastewater treatment systems.
4. Hyphomicrobium has a prostheca, which is a stalk-like extension that aids in nutrient absorption.
5. These bacteria play a significant role in the global carbon cycle by oxidizing methane and other one-carbon compounds.
