Microcolony cultivation on a soil substrate membrane system selects for previously uncultured soil bacteria.
Traditional microbiological methods of cultivation recover less than 1% of the total bacterial species, and the culturable portion of bacteria is not representative of the total phylogenetic diversity. Classical cultivation strategies are now known to supply excessive nutrients to a system and therefore select for fast-growing bacteria that are capable of colony or biofilm formation. New approa...
متن کاملA lysimeter station for contaminated soil studies
A lysimeter station has been set up by AMRA for the study of the reactive transport of contaminants in soil at the field-scale. It consists of eight lysimeters that can operate individually and simultaneously. Each lysimeter is a steel cylinder (diameter 1.14m, height 2m) filled with an undisturbed soil monolith, whose upper surface is directly exposed to the external environmental agents. A se...
متن کاملCultivation of globally distributed soil bacteria from phylogenetic lineages previously only detected in cultivation-independent surveys.
The culturability of microorganisms in a 10 cm core of an Australian pasture soil was investigated using a minimal agar medium with xylan as the growth substrate. Culturability decreased with increasing depth, from a maximum of 19% of the total microscopically countable cells in the 0-2 cm section to 2.4% in the 8-10 cm section. Seventy-one isolates from the core were identified by comparative ...
متن کاملLong-term rice cultivation stabilizes soil organic carbon and promotes soil microbial activity in a salt marsh derived soil chronosequence
Soil organic carbon (SOC) sequestration with enhanced stable carbon storage has been widely accepted as a very important ecosystem property. Yet, the link between carbon stability and bio-activity for ecosystem functioning with OC accumulation in field soils has not been characterized. We assessed the changes in microbial activity versus carbon stability along a paddy soil chronosequence shifti...
متن کاملCultivation Studies on Wart Suspensions of Verruca
The recent report by Bivins (1) on the successful cultivation of the wart agent on the chorioallantoic membrane (CAM) of embryonated hen's eggs and the report by Strauss, Bunting and Melnick (2) on the electron microscopy of elementary virus bodies in wart tissue prompted the undertaking of similar and extended experiments in this laboratory. Felsher (3) had ground up 3 warts in saline and had ...
