Tuning the motility and directionality of self-propelled colloids [PDF]

open access: yes, 2017
Microorganisms are able to overcome the thermal randomness of their surroundings by harvesting energy to navigate in viscous fluid environments. In a similar manner, synthetic colloidal microswimmers are capable of mimicking complex biolocomotion by ...

Comparing off‐flavor trends in freshwater recirculating aquaculture systems with microbially mature or immature biofilters while growing Atlantic salmon Salmo salar

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Geosmin (GSM) and 2‐methylisoborneol (MIB) cause objectionable off‐flavors in fish produced in recirculating aquaculture systems (RAS). Remediation solutions have not been developed; therefore, a study was conducted to determine if microbial maturity limits off‐flavor production. Triplicate RAS with newly established nitrification (“immature”)

Mechanically-driven spreading of bacterial populations

open access: yes, 2015
The effect of mechanical interactions between cells in the spreading of bacterial populations was investigated in one-dimensional space. A continuum-mechanics approach, comprising cell migration, proliferation, and exclusion processes, was employed to ...

Diffusion, subdiffusion, and trapping of active particles in heterogeneous media [PDF]

open access: yes, 2013
We study the transport properties of a system of active particles moving at constant speed in an heterogeneous two-dimensional space. The spatial heterogeneity is modeled by a random distribution of obstacles, which the active particles avoid.

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Diversity of Myxobacteria—We Only See the Tip of the Iceberg

open access: yesMicroorganisms, 2018
The discovery of new antibiotics is mandatory with regard to the increasing number of resistant pathogens. One approach is the search for new antibiotic producers in nature.

Myxobacterial Genomics and Post-Genomics: A Review of Genome Biology, Genome Sequences and Related ‘Omics Studies

open access: yesMicroorganisms, 2021
Myxobacteria are fascinating and complex microbes. They prey upon other members of the soil microbiome by secreting antimicrobial proteins and metabolites, and will undergo multicellular development if starved.

Draft Genome of a Type 4 Pilus Defective Myxococcus xanthus Strain, DZF1 [PDF]

open access: yes, 2014
Myxococcus xanthus is a member of the Myxococcales order within the deltaproteobacterial subdivision. Here, we report the whole-genome shotgun sequence of the type IV pilus (T4P) defective strain DZF1, which includes many genes found in strain DZ2 but ...

Stereoselective Syntheses of Cyclic Microsclerodermin Derivatives

open access: yesChemistry – A European Journal, Volume 31, Issue 60, October 27, 2025.
Six different cyclic microsclerodermin derivatives are obtained from l‐xylose and d‐arabinose via stereoselective Sakurai allylations and photochemical Arndt‐Eistert homologations. Abstract Starting from l‐xylose and d‐arabinose, six different cyclic microscleroderma derivatives were successfully obtained.

Swarm behavior of self-propelled rods and swimming flagella [PDF]

open access: yes, 2010
Systems of self-propelled particles are known for their tendency to aggregate and to display swarm behavior. We investigate two model systems, self-propelled rods interacting via volume exclusion, and sinusoidally-beating flagella embedded in a fluid ...
