  • Title: The microbial colonization of some woods of small dimensions buried in soil.
    Author: Sharp RF.
    Journal: Can J Microbiol; 1975 Jun; 21(6):784-93. PubMed ID: 238728.
    Abstract:
    Several species of wood veneer, including some in a green undried state, were buried in various soils, and at intervals the colonists were isolated and identified. In addition, veneers were deteriorated for different periods of time, sterilized, and then reburied in the same soil. Isolates were obtained before sterilization and compared with those found afterwards. In each case the colonization involved a small number of microfungi and, because similar species were repeatedly isolated, an absence of succession under laboratory conditions was indicated. Deteriorating cubes of weed were periodically assayed for their glucose content, pH of exudates, and the release of microbial cellulase and amylase. A lack of any consistent change in colonist activity, with respect to these factors, again indicated an absence of stages during decay. The colonization pattern was contrasted with successions described in previous studies and the simplest explanation was given for the differences found.
