“…from various soil samples. Hayakawa et al (1995b) also found that vanillin is successful as a chemoattractant for isolating Catenuloplanes spp. from soil; the use of vanillin also enables the isolation of members of the recently discovered genus Virgosporangium (Tamura et al, 2001).…”

“…The genus Actinoplanes, another zoosporic actinomycete genus, was first described by Couch in 1950 (2). Selective methods, such as pollen or keratin baiting techniques (3,5,11,16,22), chemotactic methods (5,10,13,(23)(24), and centrifugation methods (18,21,27), have been developed to isolate zoosporic actinomycetes that are difficult to isolate by conventional dilution plate methods.…”

A simplified enrichment method in which centrifugation is used for selective isolation of Sporichthya strains from soil is described. Gellan gum plus 2 mM CaCl2 stimulated growth ofSporichthya polymorpha KCC A0089 so that this organism was readily recognized on an isolation plate. High yields of motile spores were obtained by using a flooding solution containing 0.1% skim milk in 10 mM MOPS (morpholinepropanesulfonic acid) (pH 8.0) and then incubating the preparation at 27°C for 60 min and centrifuging it at 1,000 × g for 10 min. Dry heat treatment at 80°C for 60 min increased the ratio of Sporichthya colonies to nonfilamentous bacteria on a gellan gum plate. Since S. polymorpha was sensitive to 14 antibiotics, including nalidixic acid, addition of these antibiotics was not suitable for isolatingSporichthya strains. Our isolates were identified asSporichthya strains on the basis of their morphological and chemotaxonomic characteristics. By combining the techniques described above, we isolated a number of Sporichthya strains from 21 soil samples, which were collected in Belgium, France, India, Japan, Papua New Guinea, Spain, Taiwan, the United Kingdom, and the United States. Sporichthya strains are widely distributed in the world. To our knowledge, this is the first time thatSporichthya strains have been isolated from locations other than the United States or Japan.

Dac.ty.lo.spo.ran'gi.um. Gr. n. daktylos finger; Gr. n. spora a seed, and in biology a spore; Gr. neut. n. angeion (L. translit. angium ) vessel; N.L. neut. n. Dactylosporangium an organism with finger‐shaped, spore‐containing vessels (sporangia). Actinobacteria / Actinobacteria / Micromonosporales / Micromonosporaceae / Dactylosporangium Finger‐shaped to claviform sporangia (0.6–1.4 × 2.5–6.0 µm) are formed on short sporangiophores on the substrate mycelium . They develop singly or in clusters above the surface of the substrate. Each sporangium contains a single row of normally three to four spores . The spores are oblong , ellipsoidal , ovoid , or slightly pyriform (0.4–1.3 × 0.5–1.8 µm) and motile by means of a polarly inserted tuft of flagella. True aerial mycelium is not formed. Hyphae of the substrate mycelium are 0.5–1.0 µm in diameter, branched, and rarely septate. Large single spores, globose bodies (1.7–2.8 µm in diameter) are formed on short branches on substrate mycelium. Organisms are Gram‐stain‐positive and not acid‐fast. The peptidoglycan of the cell walls contains meso ‐ diaminopimelic acid ( meso ‐ DAP ) and glycine , with xylose and arabinose as characteristic sugars of whole‐cell hydrolysates. Colonies grow on various agar media. They are compact, somewhat tough and leathery, and mostly flat or sometimes elevated with a smooth to slightly wrinkled surface. The color of the substrate mycelium is pale orange to deep orange , rose or wine‐colored to brown . Aerobic, chemo‐organotrophic, with optimum growth between 25 and 37°C and at pH 6.0–7.0. DNA G + C content ( mol %): 71–73 ( T m ). Type species : Dactylosporangium aurantiacum Thiemann, Pagani and Beretta 1967, 43 AL .
