Bacterial Tracking of Motile Algae Assisted by Algal Cell’s Vorticity Field
Microbial Ecology - Tập 58 - Trang 63-74 - 2008
Previously published experimental work by other authors has shown that certain motile marine bacteria are able to track free-swimming algae by executing a zigzag path and steering toward the algae at each turn. Here, we propose that the apparent steering behaviour could be a hydrodynamic effect, whereby an algal cell’s vorticity and strain-rate fields rotate a pursuing bacterial cell in the approp...... hiện toàn bộ
Composition of the Phyllospheric Microbial Populations on Vegetable Plants with Different Glucosinolate and Carotenoid Compositions
Microbial Ecology - Tập 56 - Trang 364-372 - 2008
The plant phyllosphere is intensely colonized by a complex and highly diverse microbial population and shows pronounced plant-species-specific differences. The mechanisms and influencing factors determining whether and in which density microorganisms colonize plant phyllosphere tissues are not yet fully understood. One of the key influencing factors is thought to be phytochemical concentration and...... hiện toàn bộ

Aggregates of Resident Bacteria Facilitate Survival of Immigrant Bacteria on Leaf Surfaces
Microbial Ecology - Tập 49 - Trang 343-352 - 2005
The fate of immigrant bacterial cells on leaves under stressful conditions was determined as a function of the anatomical features and the local spatial density of resident cells at their landing site. Pantoea agglomerans 299R was established on bean leaves and the survival of immigrant cells of Pseudomonas fluorescens A506 and Pseudomonas syringae B728a, as well as P. agglomerans itself, was dete...... hiện toàn bộ
Evaluation of media and techniques to enumerate heterotrophic microbes from karst and sand aquifer springs
Microbial Ecology - Tập 31 - Trang 115-124 - 1996
Several media and techniques were compared for their efficiency to enumerate viable heterotrophs from both a karst and sand aquifer spring. A medium designed to enumerate bacteria from nutrient-poor waters (HCFU) as well as R2A medium proved superior to tryptic soy agar; however, the difference was always less than one order of magnitude. Membrane filtration resulted in lower counts of microbes th...... hiện toàn bộ
Initial Phylogenetic Relatedness of Saprotrophic Fungal Communities Affects Subsequent Litter Decomposition Rates
Microbial Ecology - Tập 69 - Trang 748-757 - 2014
Ecosystem-level consequences of biodiversity loss of macroorganisms are well understood, while the repercussions of species extirpation in microbial systems are not. We manipulated species richness and phylogenetic relatedness of saprotrophic fungi in situ in a boreal forest to address this issue. Litter decomposition rates (as total mass loss) after 2 months were significantly higher in the least...... hiện toàn bộ
A Survey on Plant Viruses in Natural Brassicaceae Communities Using RNA-Seq
Microbial Ecology - - 2018
Studies on plant viruses are biased towards crop diseases and little is known about viruses in natural vegetation. We conducted extensive surveys of plant viruses in wild Brassicaceae plants occurring in three local plant communities in central Japan. We applied RNA-Seq with selective depletion of rRNA, which allowed us to detect infections of all genome-reported viruses simultaneously. Infections...... hiện toàn bộ
Exopolysaccharide production and attachment strength of bacteria and diatoms on substrates with different surface tensions
Microbial Ecology - Tập 32 - Trang 23-33 - 1996
Attachment strength and exopolysaccharide (EPS) production of Pseudomonas sp. (bacteria) and the diatom Amphora coffaeformis were studied on six different substrata with surface tensions between 19 and 64.5 mN m−1. Test panels of the materials were exposed to bacterial cultures between 3 and 120 hours, and to diatom cultures between 48 and 72 hours. Exopolysaccharide production by surface-associat...... hiện toàn bộ
