Notice: Cessation of distribution of Leeuwenhoekiella marinoflava JCM 8517T / Start of distribution of JCM 31008T for authentic Leeuwenhoekiella marinoflava

December 14, 2015

Leeuwenhoekiella marinoflava (formerly Cytophaga marinoflava) JCM 8517T was accessioned from NCIMB* (UK) in 1992 and had been distributed since 1996. Recently, a user informed us that JCM 8517T was identified as a Cellulophaga strain by the 16S rRNA gene sequence analysis and we confirmed it. We obtained and confirmed authentic Leeuwenhoekiella marinoflava from LMG** (Belgium) and this strain is available as JCM 31008T. Distribution of JCM 8517T has been stopped.

Since 2011, we have examined DNA sequences of the PCR-amplified rRNA gene of newly deposited strains and compared the sequences with those provided by depositors of the strains to confirm the authenticity of the cultures. But, for the strains deposited before 2011 such as this case, we did not confirm the authenticity by sequencing of the 16S rRNA gene at the time of their deposition. Now, we are checking the authenticity of the strains that have not yet been confirmed by gene sequencing. We appreciate your support and understanding of our activities.

We informed users of JCM 8517T of this matter in detail with our sincere apology, asked for stopping its use and provided information on the replacement.

If you have any question and concern on this matter, please feel free to contact us (
