“…Aliquots of 100 ll from each dilution were plated in duplicate on modified ISP4 agar (4 g/l soluble starch, 0.3 g/l casein, 2 g/l KNO 3 , 0.5 g/l MgSO 4 Á7H 2 O, 0.02 g/l CaCO 3 , 0.01 g/l FeSO 4 Á7H 2 O and 25 g/l agar) and starch nitrate agar plates containing 0.01% pimafucin, 10 lg/ml acridione, 5 lg/ml oxytetracycline and 0.5 lg/ml polymyxin B (Al-Zarban et al 2002;Shirling and Gottlieb 1966). After incubation at 26°C for 1 week actinomycete colonies were picked off the plates, inoculated onto ISP4 agar slopes and incubated at 26°C for 1 month.…”

Siderophore production by actinomycetes isolates from two soil sites in Western Australia

et al. 2011

The actinomycetes are metabolically flexible soil micro-organisms capable of producing a range of compounds of interest, including siderophores. Siderophore production by actinomycetes sampled from two distinct and separate geographical sites in Western Australia were investigated and found to be generally similar in the total percentage of siderophore producers found. The only notable difference was the proportion of isolates producing catechol siderophores with only 3% found in site 1 (from the north-west of Western Australia and reportedly containing 40% magnetite) and 17% in site 2 (a commercial stone fruit orchard in the hills east of Perth with a soil base ranging from sandy loam to laterite). Further detailed characterization of isolates of interest identified a Streptomyces that produced extracellularly excreted enterobactin, the characteristic Enterobacteriaceae siderophore, and also revealed some of the conditions required for enterobactin production. Carriage of the entF gene, which codes for the synthetase responsible for the final assembly of the tri-cyclic structure of enterobactin, was confirmed by PCR in this isolate. Another separate Streptomyces produced a compound that matched the UV/VIS spectra of heterobactin, a siderophore previously only described in Rhodococcus and Nocardia.

“…However, differences in biomarker fatty acid concentrations must be interpreted with caution: different microbial species of the same genera can contain different amounts of specific biomarker fatty acids in their cell membranes and a single species can possess different percentages of a biomarker when grown on different carbon substrates (Dowling et al 1986). Additionally, certain fatty acids can be biomarkers for more than one group of organisms; for example 10Me16:0 is found in both sulfate reducing bacteria and actinomycete membranes (Dowling et al 1986(Dowling et al , 1988Al-Zarban et al 2002).…”

Two Invasive Plants Alter Soil Microbial Community Composition in Serpentine Grasslands

et al. 2006

Plant invasions pose a serious threat to native ecosystem structure and function. However, little is known about the potential role that rhizosphere soil microbial communities play in facilitating or resisting the spread of invasive species into native plant communities. The objective of this study was to compare the microbial communities of invasive and native plant rhizospheres in serpentine soils. We compared rhizosphere microbial communities, of two invasive species, Centaurea solstitialis (yellow starthistle) and Aegilops triuncialis (barb goatgrass), with those of five native species that may be competitively affected by these invasive species in the field (Lotus wrangelianus, Hemizonia congesta, Holocarpha virgata, Plantago erecta, and Lasthenia californica).

“…The genus Saccharomonospora, proposed by Nonomura and Ohara (1971), included actinomycetes producing predominately single spores on aerial hyphae, having type IV cell wall contained meso-diaminopimelic acid, arabinose and galactose as diagnostic whole-cell sugars, a type PII phospholipids pattern (phosphatidyl ethanolamine), and currently contains eight described species: Saccharomonospora azurea, S. caesia, S. cyanea, S. glauca, S. halophila, S. paurometabolica, S. viridis and S. xinjiangensis; only S. halophila, S. marina and S. paurometabolica are halophilic (Nonomura and Ohara 1971;Hu 1987;GreinerMai et al 1988;Hu et al 1988;Jin et al 1998;Al-Zarban et al 2002;Li et al 2003, Liu et al 2010). Another halophilic species, "Actinopolyspora iraqiensis" (Ruan et al 1994) was recently proposed to be reclassified as Saccharomonospora iraqiensis by S.K.…”

Taxonomy and antimicrobial activities of two novel halophilic Saccharomonospora strains isolated in Algerian Sahara soils

et al. 2010

View full text Add to dashboard Cite

Two novel halophilic actinomycetes, strains AH35 and AH10, isolated from saline soils obtained from the Algerian Sahara, were subjected to polyphasic taxonomic characterization. The strains showed good growth in medium containing 7, 10 and 15% NaCl with growth at temperatures of 28-42°C. The organism produced light grey-green aerial mycelium with reddish-brown or yellowbrown diffusible pigment. Micromorphology and chemotaxonomic characteristics were consistent with its assignment to the genus Saccharomonospora. Analysis of 16S rDNA gene sequences showed that AH35 and AH10 formed a robust clade with "Actinopolyspora iraqiensis", Saccharomonospora halophila and Saccharomonospora paurometabolica. However, a number of phenotypic characteristics readily distinguished strains AH35 and AH10 from these three species. The two strains showed antibacterial activity against Gram-negative bacteria such as Klebsiella pneumoniae, Salmonella enterica, Pseudomonas syringae and Agrobacterium tumefaciens.
