New Deoxyenhygrolides from Plesiocystis pacifica Provide Insights into Butenolide Core Biosynthesis

Marine Drugs, 2022
Marine myxobacteria present a virtually unexploited reservoir for the discovery of natural products with diverse biological functions and novel chemical scaffolds. We report here the isolation and structure elucidation of eight new deoxyenhygrolides (1–8)

Harnessing Gram-negative bacteria for novel anti-Gram-negative antibiotics. [PDF]

Microb Biotechnol
In this mini‐review, we highlight prominent examples of novel anti‐Gram negative natural products produced by isolated Gram‐negative bacteria that are currently in pre‐clinical development. Furthermore, we will provide insights into the considerations and strategies behind the discovery of these agents and their putative applications.

Identification of a solo acylhomoserine lactone synthase from the myxobacterium Archangium gephyra

Scientific Reports, 2021
Considered a key taxon in soil and marine microbial communities, myxobacteria exist as coordinated swarms that utilize a combination of lytic enzymes and specialized metabolites to facilitate predation of microbes.

On the mysterious propulsion of Synechococcus. [PDF]

PLoS ONE, 2012
We propose a model for the self-propulsion of the marine bacterium Synechococcus utilizing a continuous looped helical track analogous to that found in Myxobacteria [1].

Distribution and ecology of the generalist lactic acid bacterium Carnobacterium maltaromaticum in different freshwater habitats: Metabolic and antagonistic abilities

Environmental Microbiology, Volume 25, Issue 12, Page 3556-3576, December 2023., 2023
The lactic acid bacterium C. maltaromaticum was widely distributed in low concentrations in Danish freshwater environments except for locations with pH < 5. Isolates displayed a versatile metabolism and a relatively high frequency of mostly low‐intensity antagonism within the species, but unrelated to phylogeny or location. Although C.

Tartrolon sensing and detoxification by the Listeria monocytogenes timABR resistance operon

Molecular Microbiology, Volume 120, Issue 5, Page 629-644, November 2023., 2023
The natural reservoir of the human pathogen Listeria monocytogenes is the environment. We here describe the L. monocytogenes timABR genes as a novel resistance cassette providing resistance against tartrolon B, an antibiotic produced by environmental competitors. Abstract Listeria monocytogenes is a foodborne bacterium that naturally occurs in the soil.

Diatom adhesive trail proteins acquired by horizontal gene transfer from bacteria serve as primers for marine biofilm formation

New Phytologist, Volume 240, Issue 2, Page 770-783, October 2023., 2023
Summary Biofilm‐forming benthic diatoms are key primary producers in coastal habitats, where they frequently dominate sunlit intertidal substrata. The development of gliding motility in raphid diatoms was a key molecular adaptation that contributed to their evolutionary success.

A novel xylanase from a myxobacterium triggers a plant immune response in Nicotiana benthamiana. [PDF]

Mol Plant Pathol
CcXyn, a novel xylanase from the myxobacterium Cystobacter sp. 0969, induces hypersensitive response (HR) and activates defence mechanisms by interacting with the NbRXEGL1 receptor on the cell membrane of Nicotiana benthamiana. Abstract Xylanases derived from fungi, including phytopathogenic and nonpathogenic fungi, are commonly known to trigger plant ...
