Actinoplanes liguriensis sp. nov. and Actinoplanes teichomyceticus sp. nov

The taxonomic status of ‘Actinoplanes liguriae’ A/6353 and ‘Actinoplanes teichomyceticus’ AB8327 was established by using a polyphasic approach. Strains A/6353 and AB8327 form distinct phylogenetic lineages in the 16S rRNA gene tree of members of the genus Actinoplanes and are related moderately and closely to Actinoplanes rectilineatus and Actinoplanes cyaneus, respectively. Morphological, cultural and physiological properties indicated that strains A/6353 and AB8327 represent separate, novel species of the genus Actinoplanes, Actinoplanes liguriensis sp. nov. (type strain A/6353T=FH 2244T=DSM 43865T=ATCC 31048T=BCRC 12121T=CBS 355.75T=IMSNU 22127T=JCM 3250T=KCTC 9536T=KCC A-0250T=NBRC 13997T=NCIMB 12636T=NRRL B-16723T=SANK 62178T) and Actinoplanes teichomyceticus sp. nov. (type strain AB8327T=FH 2149T=DSM 43866T=ATCC 31121T=BCRC 12106T=FERM P-3462T=IMSNU 20043T=IMET 9254T=JCM 3252T=KCC A-0252T=KCTC 9543T=NBRC 13999T=NCIMB 12640T=NRRL B-16726T=SANK 60479T).

Eight new species of the genus Micromonospora, Micromonospora citrea sp. nov., Micromonospora echinaurantiaca sp. nov., Micromonospora echinofusca sp. nov. Micromonospora fulviviridis sp. nov., Micromonospora inyonensis sp. nov., Micromonospora peucetia sp. nov., Micromonospora sagamiensis sp. nov., and Micromonospora viridifaciens sp. nov

A previous phylogenetic study on type strains of the genus Micromonospora and Micromonospora species bearing non-validly published names has pointed towards the species status of several of latter strains. Subsequent studies on morphological, cultural, chemotaxonomic, metabolic, and genomic properties, and on whole cell mass spectrometric analyses by matrix adsorbed laser desorption/ionization time-of-flight (MALDI-TOF) confirmed the species status, leading to the proposal of eight new Micromonospora species: Micromonospora citrea sp. nov., type strain DSM 43903T, Micromonospora echinaurantiaca sp. nov., type strain DSM 43904T, Micromonospora echinofusca sp. nov., type strain DSM 43913T, Micromonospora fulviviridis sp. nov., type strain DSM 43906T, Micromonospora inyonensis sp. nov., type strain DSM 46123T, Micromonospora peucetia sp. nov., type strain DSM 43363T, Micromonospora sagamiensis sp. nov., type strain DSM 43912T and Micromonospora viridifaciens sp. nov., type strain DSM 43909T.

Three new antibiotic producing species of the genus Amycolatopsis, Amycolatopsis balhimycina sp. nov., A. tolypomycina sp. nov., A. vancoresmycina sp. nov., and description of Amycolatopsis keratiniphila subsp. keratiniphila subsp. nov. and A. keratiniphila subsp. nogabecina subsp. nov

Screening of Indian soils for strains producing antibiotics active against methicillin resistant staphylococci resulted in the isolation of the actinomycetes FH 1894T, ST 101170T, and FH 1893T, producing novel glycopeptide antibiotics and a polyenic compound, respectively. Studies of the cellular fatty acids and the absence of mycolic acids as well as the 16S rRNA gene sequence analysis of the producers indicated their membership to the genus Amycolatopsis. Comparison of genomic and metabolic properties of these strains with known species of this genus indicated that they represent new species for which the names Amycolatopsis balhimycina (type strain FH 1894T, DSM 44591T) and Amycolatopsis vancoresmycina (type strain ST 101170T, DSM 44592T) are proposed. The producer of the antibiotic Tolypomycin, strain IFO 14664T, representing the invalid species "Amycolatopsis tolypophorus", was also included in this investigation. As this strain was found to represent a valid species of the genus Amycolatopsis the name Amycolatopsis tolypomycina is proposed for this species, with the type strain IFO 14664T (DSM 44544T). The producer of the antibiotic Nogabecin, strain FH 1893T, was found to be closely related to the type strain of A. keratiniphila DSM 44409T which justifies the description of two subspecies of this species, A. keratiniphila subsp. keratiniphila DSM 44409T and A. keratiniphila subsp. nogabecina DSM 44586T.
