A number of Micromonospora strains isolated from the water column, sediment, and cellulose baits placed in freshwater lakes were shown to be able to degrade cellulose in lake water without any addition of nutrients. A selective isolation method was also developed to demonstrate that CFU arose from both spores and hyphae that inhabit the lake environment. Gyrase B gene sequencing performed on the isolates identified a number of new centers of variation within Micromonospora, but the most actively cellulolytic strains were recovered in a single cluster that equated with the type species of the genus, M. chalcea.
