Synergistic interactions in the microbial world [PDF]

Antonie van Leeuwenhoek, 2002
After several decades of microbiological research has focused on pure cultures, synergistic effects between different types of microorganisms find increasing interest. Interspecies interactions between prokaryotic cells have been studied into depth mainly with respect to syntrophic cooperations involved in methanogenic degradation of electron-rich ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A novel strain isolated from methane seeps in the Kattegat belongs to the planctomycetal species Novipirellula methanifontis sp. nov.

Scientific Reports
Here, we present the bacterial isolate SH528T, a planctomycetal strain from the collection of Heinz Schlesner (Kiel University), a pioneer in the research on budding bacteria. Genomic and physiological features of the novel strain are characterized along

Bacterial Adaptation during Chronic Respiratory Infections

Pathogens, 2015
Chronic lung infections are associated with increased morbidity and mortality for individuals with underlying respiratory conditions such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD). The process of chronic colonisation allows

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Microbial community development in a dynamic gut model is reproducible, colon region specific, and selective for Bacteroidetes and Clostridium cluster IX

, 2010
Dynamic, multicompartment in vitro gastrointestinal simulators are often used to monitor gut microbial dynamics and activity. These reactors need to harbor a microbial community that is stable upon inoculation, colon region specific, and relevant to in ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Microbial control of root-pathogenic fungi and oomycetes

, 2015
The rhizosphere is a complex and dynamic environment in which microbes introduced to control root pathogens must establish and maintain populations of sufficient size and activity to antagonize pathogens directly or by manipulating the host plant’s own ...

Characterisation of Kothea flammea gen. nov., sp. nov., a planctomycete of the family Pirellulaceae isolated from Fjord Schlei in the Baltic Sea

Scientific Reports
The flame-like reddish to orange-pigmented planctomycetal strain SH139T was isolated from brackish water obtained from Fjord Schlei in Northern Germany as part of an isolation effort led by Heinz Schlesner at Kiel University between the 1980s and early ...
