- Karin S. Moß, Stefan C. Hartmann, Isabell Müller, Christina Fritz, Sven Krügener, Susanne Zibek, Thomas Hirth, Steffen Rupp:
Amantichitinum ursilacus gen. nov., sp. nov., a chitin-degrading bacterium isolated from soil. Int. J. Syst. Evol. Microbiol., 2013, 63,
98-103.
Noncorroding colonies. Colonies on modified Luria-Bertani agar are milky white to
beige, circular, convex and about 1 mm in diameter. Grows between 10 and 35 ºC
and at pH values of 6-9; optimum pH 7. Can grow in the absence of NaCl.
Facultatively anaerobic.
