The taxonomic status of 14 strains of members of the genus Acinetobacter isolated from floral nectar of wild Mediterranean insect-pollinated plants, which did not belong to any previously described species within this genus, was investigated following a polyphasic approach. Confirmation that these strains formed two separate lineages within the genus Acinetobacter was obtained from comparative ...
Nineteen new Corynebacterium species or taxa described since 1995 have been associated with human disease. We report the characteristics of 72 strains identified as or most closely resembling 14 of these newer, medically relevant Corynebacterium species or taxa, as well as describe in brief an isolate of Corynebacterium bovis, a rare pathogen for humans. The bacteria studied in this report were...
A novel actinomycete, strain S10(T), was isolated from rhizosphere soil of wild Vitis vinifera in Thinghir, Ouarzazate Province, Southern Morocco. The taxonomic status of this strain was established using a polyphasic approach. Strain S10(T) had white-grey aerial mycelium with long, spiral spore chains bearing smooth surfaced spores and produced a yellow diffusible pigment. Chemotaxonomic analy...
A soil isolate, strain CC-AB07T, was characterized using a polyphasic approach. This organism had chemotaxonomic and morphological properties consistent with its classification in the genus Gordonia. 16S rRNA gene sequence analysis showed that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Gordonia, its closest neighbours being...
An actinomycete strain, ID05-A0528(T), was isolated using the SDS-yeast extract pre-treatment method from soil under mahogany (Swietenia mahogani) trees in West Timor, Indonesia, and was examined by using a polyphasic taxonomic approach. Chemotaxonomic and phylogenetic characterizations demonstrated that the novel strain belongs to the genus Dietzia. 16S rRNA gene sequencing studies showed that...
Fourteen mycobacterial strains isolated from pulmonary samples of independent patients in the state of Pará (Brazil), and three strains isolated in Italy, were characterized using a polyphasic approach. Thorough genetic investigation, including whole-genome sequencing, demonstrated that the strains belong to the M. simiae complex, being most closely related to Mycobacterium interjectum. For 14 ...
Several toxigenic trichothecene-producing and nonproducing Fusarium species are involved in Fusarium head blight, which reduces both crop yield and quality in cereals. Climate change has altered crop production in many countries, and this in turn influences the pathogen populations. E.g. in northern areas a risk will be new toxigenic Fusarium species spreading to the north due to higher tempera...
Fourteen strains were isolated from nitrogen-fixing nodules on the roots of plants of the genus Mimosa growing in Taiwan, Brazil and Venezuela. On the basis of 16S rRNA gene sequence similarities, all of the strains were previously shown to be closely related to each other and to belong to the genus Burkholderia. A polyphasic approach, including DNA-DNA reassociation, whole-cell protein analysi...
A polyphasic approach was applied to characterize 35 G. diazotrophicus isolates obtained from sugarcane varieties cultivated in Brazil. The isolates were analyzed by phenotypic (use of different carbon sources) and genotypic tests (ARDRA and RISA-RFLP techniques). Variability among the isolates was observed in relation to the carbon source use preference. Glucose and sucrose were used by all is...
For several years, our laboratory has isolated numerous bacterial strains from soils and wastewater contaminated with toxic compounds in order to find useful bacteria that can degrade phenolic compounds such as phenol, chlorophenol, and nitrophenol. By enrichment, many phenolic compound-degrading bacteria have been isolated (Bae et al., 1996a, b; Baek et al., 2001; Yoon et al., 1999, 2000). Fur...
