“…This is rather surprising considering their copiotrophic and photoautotroph-associated nature (Evtushenko and Takeuchi 2006). It is more likely that the isolates cultivated here were of subglacial origin, as no representatives of the genus were found in surface ice or anywhere else along the transect.…”

Glacier forelands are excellent sites in which to study microbial succession because conditions change rapidly in the emerging soil. Development of the bacterial community was studied along two transects on lateral moraines of Ecology Glacier, King George Island, by culture-dependent and culture-independent approaches (denaturating gradient gel electrophoresis). Environmental conditions such as cryoturbation and soil composition affected both abundance and phylogenetic diversity of bacterial communities. Microbiocenosis structure along transect 1 (severe cryoturbation) differed markedly from that along transect 2 (minor cryoturbation). Soil physical and chemical factors changed along the chronosequence (time since exposure) and influenced the taxonomic diversity of cultivated bacteria, particularly along transect 2. Arthrobacter spp. played a pioneer role and were present in all soil samples, but were most abundant along transect 1. Cultivated bacteria isolated from transect 2 were taxonomically more diverse than those cultivated from transect 1; those from transect 1 tended to express a broader range of enzyme and assimilation activities. Our data suggest that cryoturbation is a major factor in controlling bacterial community development in postglacial soils, shed light on microbial succession in glacier forelands, and add a new parameter to models that describe succession phenomena.

“…The characteristic cell-wall diamino acid was 2,4-diaminobutyric acid (DAB), which is typical for the genus Agrococcus (Evtushenko & Takeuchi, 2006). In contrast, species of the genus Microbacterium are characterized by the presence of ornithine or lysine as the diagnostic diamino acid (Evtushenko & Takeuchi, 2006). Thus, the cell-wall composition substantiates the affiliation of strain K 114/01 T to the genus Agrococcus.…”

“…The species of the genera Microbacterium, Leifsonia, Curtobacterium, Clavibacter, Frigoribacterium, Agreia and Plantibacter, in particular, colonize the surfaces of various plant species (Evtushenko & Takeuchi, 2006). In contrast, Agrococcus species have not been isolated from plant surfaces.…”

“…The amino acids and peptides in cell-wall hydrolysates of the peptidoglycan of strain K 114/01 T were analysed using two-dimensional ascending TLC on cellulose plates with the solvent system described by Schleifer & Kandler (1972). The characteristic cell-wall diamino acid was 2,4-diaminobutyric acid (DAB), which is typical for the genus Agrococcus (Evtushenko & Takeuchi, 2006). In contrast, species of the genus Microbacterium are characterized by the presence of ornithine or lysine as the diagnostic diamino acid (Evtushenko & Takeuchi, 2006).…”

The taxonomic position of a group of actinobacterial strains isolated from the phyllosphere of potato plants was investigated by using a polyphasic approach. Although the similarity values for their 16S rRNA gene sequences suggested an intermediate position between Microbacterium and Agrococcus, the phylogenetic tree demonstrated a clear clustering of the representative strain, K 114/01 T , within the genus Agrococcus. The presence of 2,4-diaminobutyric acid as the diagnostic diamino acid in the cell-wall peptidoglycan of strain K 114/01 T substantiated the affiliation to the genus Agrococcus. An analysis performed using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry revealed highly similar spectral patterns for the isolated strains, which, together with their conformity regarding a multitude of phenotypic features, supported their affiliation to the same species. Differences in several physiological features, peptidoglycan and menaquinone composition and whole-cell fatty acid profiles enabled discrimination of the phyllosphere isolates with respect to recognized Agrococcus species. As the 16S rRNA gene sequence similarity values were below 97 %, the strains isolated from the phyllosphere of potato plants represent a novel species of the genus Agrococcus, for which the name Agrococcus versicolor sp. nov. is proposed. The type strain is K 114/01 T (5DSM 19812 T 5LMG 24386 T ).

“…The genera of the family can be readily differentiated on the basis of chemotaxonomic characters, such as diagnostic diamino acids of the cell-wall peptidoglycan (ornithine, lysine, 2,4-diaminobutyric acid), peptidoglycan type, major menaquinones and cellular fatty acid composition. Members of the family occur in diverse environments, including seawater and marine mud (Evtushenko & Takeuchi, 2003;Han et al, 2003). In this paper, we describe an actinomycete isolated from seaweed, which represents a novel species of a new genus within the family Microbacteriaceae.…”

Labedella gwakjiensis gen. nov., sp. nov., a novel actinomycete of the family Microbacteriaceae Soon Dong LeeCorrespondence Soon Dong Lee sdlee@cheju.ac.kr Department of Science Education, Cheju National University, Jeju 690-756, Republic of Korea A Gram-positive, non-motile, non-mycelium-forming, rod-shaped actinomycete, designated KSW2-17 T , was isolated from dried seaweed collected from beach sand along the coast of Jeju, Republic of Korea. The organism had ornithine as the diagnostic cell-wall diamino acid, MK-10 and MK-11 as the major menaquinones, and phosphatidylglycerol and diphosphatidylglycerol as polar lipids. The fatty acid profile included predominantly iso-and anteiso-branched acids and a minor amount of tuberculostearic acid (10-methyl C 18 : 0 ). The DNA G+C content was 68.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the seaweed isolate formed a distinct clade within the radiation of the family Microbacteriaceae and had highest sequence similarity (96.1-96.3 %) to members of the genera Cryobacterium, Frigoribacterium and Rathayibacter. On the basis of phenotypic and genotypic evidence, strain KSW2-17 T is considered to represent a novel species of a new genus, for which the name Labedella gwakjiensis gen. nov., sp. nov. is proposed. The type strain is KSW2-17 T (5JCM 14008 T 5KCTC 19176 T ).
