Active Microbial Sulfur Disproportionation in the Mesoproterozoic [PDF]
Science, 2005 The environmental expression of sulfur compound disproportionation has been placed between 640 and 1050 million years ago (Ma) and linked to increases in atmospheric oxygen. These arguments have their basis in temporal changes in the magnitude of 34 S/ 32 S fractionations between sulfate and ...

Immunosuppressive activity of a microbial product
Folia Pharmacologica Japonica, 1997 Microbial products have amazing diversity and complexity in their chemical structures as well as in their biological activities. The successful discovery and development of FK506 (Tacrolimus) adds a new example showing that microbial products are agents with potential therapeutic benefits.

Influence of interfaces on microbial activity
Microbiological Reviews, 1990 Bacterial adhesion in natural and artificial systems has been critically reviewed to investigate the influences exerted by the presence of interfaces. Numerous investigations have demonstrated that, in the presence of a solid phase, the activity of bacterial cultures is changed. Reviewing relevant literature, two problems were encountered. One is of an

Stability of Aggregates Made by Earthworms in Soils with Organic Additives
Agronomy, 2021 Earthworm activity is a key factor in creating soil aggregates, but introduced organic matter and abiotic factors are also equally important. The purpose of this study was to investigate the stability of aggregates made by earthworms in soils with ...

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.

Impact of soil biochemical properties on yield and sustainability of integrated crop-livestock production systems without mineral fertilization [PDF]
Revista Brasileira de Ciência do SoloSustainable agricultural systems, such as integrated crop-livestock systems under no-tillage, represent effective strategies for improving the soil microbiota, promoting nutrient cycling, and leading to gains in crop yield.

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.

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.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
