Zhenhengia is a genus of Gram-positive and strictly anaerobic bacteria in the family Lachnospiraceae. It was first described in 2021 as part of a large-scale culturomics study of the human gut microbiota.^[1]

Etymology

The genus name Zhenhengia honors Zhenheng Zhu, a prominent figure in traditional Chinese medicine. The species epithet yiwuensis refers to the city of Yiwu, where Zhenheng Zhu was born.

Characteristics

Zhenhengia yiwuensis is a non-motile, rod-shaped bacterium. Cells measure approximately 0.8–1.2 µm in width and 2.3–4.0 µm in length. It grows optimally at 37°C under strictly anaerobic conditions and forms creamy colonies on standard anaerobic media after 72 hours. The DNA G+C content of the type strain is approximately 53.2 mol%.

Species

As of 2025, Z. yiwuensis is the only validly published species in this genus.
