Caldalkalibacillus is an aerobic and spore-forming genus of bacteria from the family of Bacillaceae the stains either Gram-positive or Gram-variable. [1] [2] [3] [4] [5] [6] The type species of this genus is Caldalkalibacillus thermarum. [7]

Contents

Caldalkalibacillusmannanilyticus was previously a species belonging to Bacillus , a genus that has been recognized as displaying extensive polyphyly and has been restricted by recent phylogenetic studies to only include species closely related to Bacillus subtilis and Bacillus cereus. [8] [9]

The name Caldalkalibacillus is derived from the prefix "-caldalkali" (from the Latin adjective caldus, which translates to "hot" and the Latin noun alkali), and the suffix "-bacillus" (from the Latin noun bacillus, referring to a small rod). [1] Together, Caldalkalibacillus translates to bacillus living under hot and alkaline conditions).

Biochemical Characteristics and Molecular Signatures

Members of this genus are aerobic and some are motile and endospore-forming. Colonies formed are either yellow or yellowish-white in colour. Temperature range for growth is 20–65°C, with optimum growth temperature for C. mannanilyticus around 37°C, whereas C. thermarum grows optimally at 60°C. The pH range for growth is 7.5–10, with optimal growth occurring around pH 8.5–9.0. [9]

Four conserved signature indels (CSIs) were identified through genomic analyses for this genus in the following proteins: prephenate dehydrogenase, isoprenyl transferase, DUF1027 domain-containing protein and adenine deaminase, which in most cases are exclusively shared by either all or most members of this genus. [9] [3] These CSIs provide a reliable molecular means of distinguishing Caldalkalibacillus species from other Bacillaceae genera and bacteria.

Taxonomy

Caldalkalibacillus, as of May 2021, contains a total of 3 species with validly published names. [7] This branching pattern is also observed in the Genome Taxonomy Database (GTDB). [10]
