Abstract
Cel.lu.lo.si.ly.ti.ca.ce'ae. N.L. neut. n.
Cellulosilyticum
a bacterial genus; N.L. fem. pl. n.
Cellulosilyticaceae
the
Cellulosilyticum
family.
Slightly curved rod‐shaped cells
. Gram‐positive cell‐wall structure but stain Gram‐negative. Terminal spores formed. Mesophilic, optimum growth temperature is approximately 40°C.
Obligate anaerobic
. No microaerophilic or aerobic growth occurs. Produce acetate, ethanol, and/or formate as the major end products, but not butyric or propionic acid. Hydrolyze cellulose and xylan and ferment cellobiose, but not ferment lactate and pyruvate. The predominant fatty acids are C
16:0
(27.1 %), C
14:0
(9.2 %), and iso‐C
16:0
(6.4%). Phylogenetically distant from the family
Lachnospriaceae
(Clostridum cluster XIVb), a member of the phylum Firmicutes, with less than 87.7% 16S rRNA similarity. Thus far, only one genus
Cellulosilyticum
is described.
DNA G + C content (mol%)
: 33–36.
