However, there are also species belonging to this genus that do not possess this trait. In addition, the difference of up to 9 % of the 16S rRNA gene sequences of 33 type strains compared with the first isolated type species, <em>A. acidocaldarius</em> DSM 446^T, exceeds the 5.5 % threshold, which is typically used for the demarcation of a genus. This suggested that the taxonomy of the genus required a re-examination. We performed a phylogenomic and chemotaxonomic survey of the genus <em>Alicyclobacillus</em>. Phylogenetic trees based on the 16S rRNA gene and comparison of whole proteomes reconstructed from their genomes reveal that the genus <em>Alicyclobacillus</em> is reflected by two distinct clades; one represented by 14 type strains with a &gt;94.1 % 16S rRNA gene similarity to <em>A. acidocaldarius</em> DSM 446^T, and a second clade (composed of 14 type strains including <em>A. cycloheptanicus</em>) with a similarity of 91–94 %. This distinction fits well with their reported ability to produce alicyclic FAs, also revealed by the detection of two putative biosynthetic gene clusters (BGC) encoding their biosynthetic pathway in their genomes. The first BGC is responsible for the production of cyclohexane carboxylic acid-CoA and comprises five genes encoding proteins acting as an adjusted side branch of the shikimate pathway. The putative second BGC, responsible for production of cycloheptane carboxylic acid-CoA, comprises six genes encoding proteins acting as a side branch of the catabolic phenylacetic acid pathway. All <em>Alicyclobacillus</em> species of the first clade produce <em>ω</em>-cyclohexyl FAs and their genomes possess the corresponding BGC. In the second cluster, some species produce <em>ω</em>-cyclohexyl FAs, some produce <em>ω</em>-cycloheptyl FAs, whilst quite some members are not producing any alicyclic FAs. This corresponds to the presence or absence of the two BGCs in their genomes.

The bacteroidetes strain ABcell3^T was separated in pure culture from colonies formed in soft agar with amorphous cellulose, while the gammaproteobacterial satellite, strain ABcell2^T, was selectively purified using glucomannan instead of cellulose. ABcell3^T was identified as a new-genus lineage in the family <em>Cytophagaceae</em>, and ABcell2^T formed a new species within the genus <em>Marinimicrobium</em> (family <em>Cellvibrionaceae</em>). ABcell3^T is characterized by a complex cell morphogenesis with young cells as long flexible rods with gliding motility turning into cyst-like refractive circles. It is a highly-specialized cellulotroph, growing best with various forms of native celluloses and less actively on xyloglucan and cellobiose. ABcell2^T is a motile vibrio forming yellow pigment. It has a broad-range hydrolytic potential, growing with various glucans (but not cellulose) and sugars. Its function as a saccharolytic scavenger was confirmed by a successful reconstitution of the binary consortium on cellulose. Both bacteria are aerobic, moderately salt-tolerant alkaliphiles, growing optimally at 0.4–0.8 M total Na⁺ as carbonates and pH 9.0–9.5. Functional genome analysis of strain ABcell3^T identified fourteen gene copies for potential cellulases from the GH families 5_1/5_2, 9 and 8. The genome of ABcell2^T also contains four GH9 cellulase genes but none of the others. Instead, multiple copies of different GH5 subfamilies were present with a potential hemicellulose substrate specificity.
