| streptomyces africanus sp. nov., a novel streptomycete with blue aerial mycelium. | an actinomycete with blue aerial mycelium and yellow substrate mycelium was isolated from a suburban soil sample collected in cape town, south africa and named strain cpjvr-ht. the colour of the substrate mycelium was not sensitive to changes in ph. the organism produced spiny spores in spirales spore chains. chemical taxonomy indicated that it is a member of the genus streptomyces. strain cpjvr-ht grew at 45 degrees c and did not produce melanin or any diffusible pigments. it exhibited weak ant ... | 2004 | 15388706 |
| streptomyces speibonae sp. nov., a novel streptomycete with blue substrate mycelium isolated from south african soil. | an actinomycete with blue substrate mycelium was isolated from a soil sample in cape town, south africa, and designated strain pk-blue(t). the colour of the substrate mycelium was not sensitive to changes in ph. the organism produced hairy spores in spirales-type spore chains. chemical taxonomy indicated that it belonged to the genus streptomyces. strain pk-blue(t) produced no diffusible pigments other than melanin, grew at 45 degrees c, did not degrade adenine and exhibited no antibacterial act ... | 2003 | 12807203 |
| actinomadura rudentiformis sp. nov., isolated from soil. | as part of an antibiotic-screening programme, the actinomycete strain hmc1(t) was isolated from soil collected from the banks of the gamka river in the swartberg nature reserve, western cape province, south africa. the isolate produced branching vegetative mycelia, which entwined to form rope-like structures. it exhibited antibiosis against enterococcus faecium vana (a vancomycin-resistant clinical strain) and mycobacterium aurum a+. organic solvent extracts of the culture filtrate and mycelial ... | 2007 | 17220439 |
| actinomadura napierensis sp. nov., isolated from soil in south africa. | an actinomycete, strain b60(t), was isolated from a soil sample in napier, western cape province of south africa. based on 16s rrna gene sequence analysis and chemotaxonomy, strain b60(t) was identified as a member of the genus actinomadura. strain b60(t) produced an antibiotic with activity against escherichia coli, enterococcus faecium and mycobacterium aurum, but not against mycobacterium tuberculosis. significant differences in morphological and physiological characteristics indicate that st ... | 2005 | 15774647 |
