　Description： Growth onYM agar: After 7 days at 25 ?C, streak culture was light-orange, glistening, soft, and had an entire margin. Growth in YM broth: After 3 days at 25 ?C, cells were oval and ellipsoidal, 3.5-5.5 × 4.5-7.0 μm, single or in pair. Dalmau plate culture on corn meal agar: No branching hyphae or pseudohyphae were formed.

　Note： This species is placed in biological safety level 1. We tested 94 characters of strain 4107 using the Biolog YT MicroPlateTM. Thirty one of these characters were comparable to characteristics described by Nagahama et al. (2003). Among those tests, L-sorbose and lactose stimulate a weak reaction in type strain of R. calyptogenae (Nagahama et al., 2003). However, strain 4107 showed negative reactions at both tests. Sequence (EU669878) of rDNA ITS region of strain 4107 also showed greatest similarity (568/571 bp) with sequence (AB025996) of R. calyptogenae. The strain showed intra-species variations of physiological and genetic characteristics from type strain. Since R. calyptogenae was named, it has been considered as a deep-sea species. Strain 4107 was the first strain to be isolated and identified in Taiwan. Our finding demonstrated that the species can also be found in the surface layer.
