Hunting for cultivable Micromonospora strains in soils of the Atacama Desert
Author
Abstract
Innovative procedures were used to selectively isolate small numbers of Micromonospora
strains from extreme hyper-arid and high altitude
Atacama Desert soils. Micromonosporae were recognised on isolation plates by their ability to produce
filamentous microcolonies that were strongly
attached to the agar. Most of the isolates formed
characteristic orange colonies that lacked aerial
hyphae and turned black on spore formation, whereas
those from the high altitude soil were dry, blue-green
and covered by white aerial hyphae. The isolates
were assigned to seven multi- and eleven singlemembered groups based on BOX-PCR profiles.
Representatives of the groups were assigned to either
multi-membered clades that also contained marker strains or formed distinct phyletic lines in the
Micromonospora 16S rRNA gene tree; many of the
isolates were considered to be putatively novel
species of Micromonospora. Most of the isolates
from the high altitude soils showed activity against
wild type strains of Bacillus subtilis and Pseudomonas fluorescens while those from the
rhizosphere of Parastrephia quadrangulares and
from the Lomas Bayas hyper-arid soil showed
resistance to UV radiation.
