Limitation of Bacteria by Micro-Predators in Soil

, 1948
EIGHTY-SEVEN strains of very varied bacteria, comprising common and rare strains from soil, pigmented and non-pigmented ‘‘miscellaneous strains, and a number of plant pathogens, were tested on eight micro-predators belonging to four different groups ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Rapid Transfer of Plant Photosynthates to Soil Bacteria via Ectomycorrhizal Hyphae and Its Interaction With Nitrogen Availability

Frontiers in Microbiology, 2019
Plant roots release recent photosynthates into the rhizosphere, accelerating decomposition of organic matter by saprotrophic soil microbes (“rhizosphere priming effect”) which consequently increases nutrient availability for plants. However, about 90% of

Reduction of Ferric Compounds by Soil Bacteria [PDF]

Journal of General Microbiology, 1954
SUMMARY: Reduction of ferric lactate by washed cell suspensions of Bacillus circulans, B. megaterium and Aerobacter aerogenes takes place in the presence of suitable hydrogen donors. Ferric hydroxide is reduced when αα'-dipyridyl is present in the cell + substrate system.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Legacy Effects on the Recovery of Soil Bacterial Communities from Extreme Temperature Perturbation

Frontiers in Microbiology, 2017
The type and frequency of disturbances experienced by soil microbiomes is expected to increase given predicted global climate change scenarios and intensified anthropogenic pressures on ecosystems. While the direct effect of multiple disturbances to soil

Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Long-term Fertilization Structures Bacterial and Archaeal Communities along Soil Depth Gradient in a Paddy Soil

Frontiers in Microbiology, 2017
Soil microbes provide important ecosystem services. Though the effects of changes in nutrient availability due to fertilization on the soil microbial communities in the topsoil (tilled layer, 0–20 cm) have been extensively explored, the effects on ...

Metagenomic Sequencing Reveals that the Assembly of Functional Genes and Taxa Varied Highly and Lacked Redundancy in the Earthworm Gut Compared with Soil under Vanadium Stress

mSystems, 2022
Exploring the ecological mechanism of microbial community assembly in soil and the earthworm gut in a vanadium polluted environment could help us understand the effects of vanadium stress on microbial diversity maintenance and function, as well as the ...

Hysterangium mats and associated bacteria under eucalyptus gomphocephala in south-western Australia [PDF]

, 2012
Eucalyptus gomphocephala (tuart) is an ecologically and culturally important woodland and forest tree native to south-western Australia. Unfortunately, tuart has been markedly declining in recent decades, and the mortality rate is as high as 90% in some ...
