Species

Ureibacillus is a genus of gram-positive bacteria within the largely gram-positive Bacillota.[1] Ureibacilli are motile and form spherical endospores. The type species of the genus is Ureibacillus thermosphaericus.[1]

History

The genus Ureibacillus was split from the genus Bacillus in 2001 to encompass Bacillus thermosphaericus (now Ureibacillus thermosphaericus) as well as several newly discovered similar strains of bacteria.[1]

In 2020, multiple Lysinibacillus species were transferred into Ureibacillus based on branching patterns in various phylogenetic trees constructed based on conserved genome sequences, indicating their phylogenetic relatedness.[2] The family Caryophanaceae encompassed many branching anomalies such as this one, partially due to the reliance on 16S rRNA sequences as a method for classification, which is known to have low resolution power and give differing results depending on the algorithm used.[2]

Analysis of genome sequences from Ureibacillus species identified three conserved signature indels (CSIs) that are uniquely present in this genus in the following proteins: MFS transporter, EamA family transporter, and DNA internalization-related competence protein ComEC/Rec2.[2] These CSIs provide a reliable molecular method for distinguishing Ureibacillus species from other genera within the family Caryophanaceae and all other bacteria.
