Abstract
It is proposed that the type strain of Melittangium lichenicola (Thaxter 1892) McCurdy 1971 is ATCC 25946 (=DSM 14877), which was originally designated as a reference strain by McCurdy, and not ATCC 25944(T), as given in the Approved Lists. Swarm appearance, myxospore morphology and 16S rRNA gene sequence data suggest that ATCC 25946 is a representative of the species Melittangium lichenicola, while strain ATCC 25944 is clearly a member of the Myxococcus-Corallococcus clade. A Request for an Opinion to this effect is made to the Judicial Commission of the International Committee on Systematics of Prokaryotes.
Highlights
The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains DSM 14877, ATCC 25944T and ATCC 25946 are AM930267–AM930269
We determined the 16S rRNA gene sequence for the assigned type strain for Melittangium lichenicola, ATCC 25944T, and the sequence was deposited as GenBank accession no
Swarm and cell appearance of DSM 2275 and ATCC 25944 were in accord with the sequencing results; these cultures should be regarded as members of the Myxococcus–Corallococcus clade which have lost the ability to produce fruiting bodies and myxospores
Summary
The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains DSM 14877, ATCC 25944T and ATCC 25946 are AM930267–AM930269. We determined the 16S rRNA gene sequence for the assigned type strain for Melittangium lichenicola, ATCC 25944T, and the sequence was deposited as GenBank accession no. Similar to M94277, reportedly derived from strain ATCC 25946, the sequence clustered with sequences of Corallococcus strains rather than of Melittangium strains.
