Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Bacillaceae, Genus Bacillus, Bacillus funiculus Ajithkumar, Ajithkumar, Iriye
and Sakai 2002. Description is based on a single isolate.
Gram-variable, motile rods (peritrichous flagella), 0.8-2.0 x 4.0-6.0 µm, which form
filamentous trichomes by cellular binding. Centrally, ellipsoidal endospores in
unswollen sporangia; on prolonged incubation heat-resistant, spore-like resting cells,
which outgrow by budding, are formed.
Colonies are opaque, off-white to colorless. Aerobic. No growth in 5% NaCl.
Grows at pH 5-9 (optimum 7-8). Growth temperature 20 to 40 ºC (optimum 30 ºC).
Allantoin, urate or NaCl are not required for growth.
Isolated from activated sewage sludge (from suspended water of a wastewater treatment tank in Fukushima), Japan.
Grows in the presence of lysozyme.
