D C Coleman et al.
Flows of biomass and respiratory carbon were studied in a series of propylene-oxide sterilized soil microcosms. One-half of the microcosms received three pulsed additions of 200 ppm glucose-carbon to mimic rhizosphere carbon inputs. Biotic ...
Trophic interactions in soils as they affect energy and nutrient dynamics. III. Biotic interactions of bacteria, amoebae, and nematodes [0.03%]
土壤中影响能量和营养素动态的营养级相互作用。第三部分:细菌、变形虫和线虫的生物互作关系
R V Anderson,E T Elliott,J F McClellan et al.
R V Anderson et al.
Bacteria (Pseudomonas), amoebae (Acanthamoeba), and nematodes (Mesodiplogaster) were raised in soil microcosms with and without glucose additions. Nematode and amoebal grazing on bacteria significantly reduced bacterial populations by the e...

D C Coleman et al.
The dynamics of nutrient transformations at the soil-root interface are complex but amenable to controlled experimental study. Using a conceptual model we introduce a series of papers which ascertain the role of microfloral-faunal trophic i...
Interactions between freshwater bacteria andAnkistrodesmus braunii in batch and continuous culture [0.03%]

Batch and continuous cultures ofAnkistrodesmus braunii were established in an inorganic medium with growth rate limited by P. In batch culture, inoculation of lake water bacterial isolates ofPseudomonas sp. andFlavobacterium sp. showed that...
Effects of ingesting mercury-containing bacteria on mercury tolerance and growth rates of ciliates [0.03%]
摄入含汞细菌对纤毛虫的耐汞性和生长速率的影响

The environmental and microbiological factors that can influence heavy metal toxicity are discussed with a view to understanding the mechanisms of microbial metal tolerance. It is apparent that metal toxicity can be heavily influenced by en...
Comparison ofin Situ andin Vitro survival ofCandida albicans in seawater [0.03%]
