Specific detection and real-time PCR quantification of potentially mycophagous bacteria belonging to the genus Collimonas in different soil ecosystems.

ABSTRACT: The bacterial genus Collimonas has the remarkable characteristic that it grows at the expense of living fungal hyphae under laboratory conditions. Here, we report the first field inventory of the occurrence and abundance of Collimonas in soils (n = 45) with naturally different fungal densities, which was performed in order to test the null hypothesis that there is a relationship between the presence of Collimonas and fungal biomass. Estimates of fungal densities were based on ergosterol measurements. Each soil was also characterized in terms of its physical and chemical properties and vegetation and management types. Culturable Collimonas was identified in plate-spread soil samples by its ability to clear colloidal chitin, in combination with a Collimonas-specific restriction fragment leng
