A Gram-positive, spore-forming, aerobic, filamentous bacterium, strain JFMB-ATE(T), was isolated in 2008 during environmental screening of a plastic surface in grade C in a contract manufacturing organization in southern Germany. The isolate grew at temperatures of 25-50 °C and at pH 5.0-8.5, forming ivory-coloured colonies with sparse white aerial mycelia.(More)
An actinomycete strain, HM7(T), was isolated from sandy soil from the banks of the Arvand River, Khoramshahr, Iran. In a study conducted using a polyphasic taxonomic approach, it was found that this strain represented a novel species in the genus Nocardiopsis. Strain HM7(T) had long, branched substrate mycelia and the aerial mycelium completely fragmented(More)
A novel actinomycete, strain OFN S31(T), was isolated from a complex biofilm in the Altamira Cave, Spain. A polyphasic study was carried out to clarify the taxonomic position of this strain. Phylogenetic analysis with 16S rRNA gene sequences of representatives of the genera Corynebacterium, Dietzia, Gordonia, Millisia, Mycobacterium, Nocardia, Rhodococcus,(More)
A novel Gram-positive, multiloculated thalli-forming, aerobic, actinobacterial strain, CF9/1/1(T), was isolated in 2007 during environmental screening for xerophilic fungi in arid desert soil from the Sahara desert, Chad. The isolate grew best at a temperature range of 20-35 °C and at pH 6.0-8.5 and with 0-4% (w/v) NaCl, forming black-coloured and irregular(More)
A novel Gram-reaction-positive actinobacterial strain, designated CF5/3(T), was isolated from a sand sample obtained in the Sahara Desert, Chad. The greenish-black-pigmented isolate was aerobic and exhibited optimal growth from 25-40 °C at pH 6.0-10.0 with 0-1% (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described(More)
Three novel Gram-positive, aerobic, actinobacterial strains, CF5/2(T), CF5/1 and CF7/1, were isolated in 2007 during environmental screening of arid desert soil in the Sahara desert, Chad. Results from riboprinting, MALDI-TOF protein spectra and 16S rRNA sequence analysis confirmed that all three strains belonged to the same species. Phylogenetic analysis(More)
A novel Gram-positive, aerobic, actinobacterial strain, CF6/1T, was isolated in 2007 during environmental screening of arid desert soil in the Sahara near to Ourba, Chad. The isolate was found to grow best in a temperature range of 20–37 °C and at pH 6.0–8.5 and showed no NaCl tolerance, forming black-coloured and nearly circular colonies on GYM agar.(More)
A novel Gram-strain positive, aerobic, actinobacterial strain, designated CF11/1T, was isolated from a sand sample obtained in the Sahara Desert, Chad. The black-pigmented isolate was aerobic and exhibited optimal growth from 25 to 35 °C at pH 6.0–8.0 and with 0–8 % (w/v) NaCl, indicating that it is a halotolerant mesophile. Chemotaxonomic and molecular(More)
Five nocardioform isolates from human clinical sources were evaluated. Analysis of the nearly full-length 16S rRNA gene showed 99.9-100 % similarity among the strains. The results of a comparative phylogenetic analysis of the 16S rRNA gene sequences indicated that the isolates belonged to the genus Nocardia. Phenotypic and molecular analyses were performed(More)
Members of the genus Nocardia are responsible for cutaneous, pulmonary and disseminated human infections. From 2003 to 2008, four nocardioform strains (W8027, W8681, W9071 and W9241(T)) were isolated from patients in the state of Florida, USA. Ribosomal gene sequencing analysis suggested that a novel species of the genus Nocardia had been isolated. These(More)
