...; there is no visible septation or sporation, and branching is rare ( Figs. 1B–D ). Actinomycetes (order Actinomycetales) are prokaryotes belonging to a phylum of gram-positive bacteria, Actinobacteria ( Holt, 1994 ; Madigan et al., 1997 ). As chemoheterotrophs found mainly in soils, they play an important role...

...-feldspar from soils were dominated by Actinobacteria, and within this phylum the Actinomycetales were dominant. Scanning electron microscopy studies of feldspars from soils with known periods of exposure show clear corrosion of K-feldspar and the occurrence ( Fig. 4 ) within the cavities thus formed...

... ). Actinomycetes are now classified within Actinomycetales, the largest of five orders comprising the phylum Actinobacteria, which is sister to low G-C, Gram-positive bacteria ( Embley and Stackebrandt, 1994 ; Stackebrandt et al., 1997 ; Zhi et al., 2009 ). Actinomycete colonies grow via the production of dense...

... occurs in the gram positive bacterial group Actinomycetales ( Krügel et al. 1999 ; Phadwal 2005 ), and a genome library search for genes involved in isorenieratene biosynthesis suggests that cyanobacteria may have this capacity as well (Woodward Fischer, personal communication). In general...
