Comparative analysis of canonical and noncanonical rhodopsins in Amphidinium carterae and Karlodinium veneficum

Journal of Phycology, Volume 62, Issue 2, Page 360-376, April 2026.
Abstract Rhodopsins are ancient and versatile light‐sensitive proteins, widely distributed across microbial life. In dinoflagellates, however, their diversity and function remain poorly understood, owing to the lineage's extreme genomic divergence. Here, we surveyed the rhodopsin complements of two dinoflagellates, Amphidinium carterae and Karlodinium ...

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures

, 2018
We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.

Functional stability and community dynamics during spring and autumn seasons over 3 years in Camargue microbial mats [PDF]

, 2018
Microbial mats are complex biofilms in which the major element cycles are represented at a millimeter scale. In this study, community variability within microbial mats from the Camargue wetlands (Rhone Delta, southern France) were analyzed over 3 years ...

From Lake Victoria to the Tap: Antibiotic Resistance and Pathogenic Contamination of Kisumu City Water Supply and Wastewater Network

Tropical Medicine &International Health, Volume 31, Issue 4, Page 547-559, April 2026.
ABSTRACT Waterborne diseases and antimicrobial resistance (AMR) pose mounting public health threats across sub‐Saharan Africa, particularly in rapidly urbanising regions dependent on untreated or poorly treated surface waters. This study applied shotgun metagenomic sequencing to characterise microbial communities, virulence factors and antibiotic ...

Survival strategies of microorganisms in extreme saline environments [PDF]

, 1986
Halophilic representatives are found in all main lines of evolutionary descendence of microbes: in archaebacteria, Gram-negative and Gram-positive eubacteria, and also in eucaryotes.

Halobacteria carotenoid extraction

, 2020
I've been reading into bacteriochlorophyll a utilizing alphaproteobacteria recently, prompted by the question of selecting among wildtype microbes and studying their evolution long-term. Chances are, whatever the sample I'll be able to screen from the East River would be carotenoid producing aerobic photoheterotroph, likely from the upper sediment ...

High‐Resolution Community Profiling of Active Bacteria and Eukaryotes in Replant‐Diseased Blueberry Farm Soils From New Jersey, USA

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Long read bacterial and eukaryotic ribosomal operon sequencing combined with stable isotope probing (SIP) allowed the differentiation of microbiomes in low‐ and high‐yield blueberry farm soils. This report may ultimately be used to improve productivity and potentially detect the responsible pathogenic agent(s) or other deleterious microbes.

Genetically encoded reporters for hyperpolarized xenon magnetic resonance imaging [PDF]

, 2014
Magnetic resonance imaging (MRI) enables high-resolution non-invasive observation of the anatomy and function of intact organisms. However, previous MRI reporters of key biological processes tied to gene expression have been limited by the inherently low

Experimental antibiotic treatment identifies potential pathogens of white band disease in the endangered Caribbean coral Acropora cervicornis [PDF]

, 2014
Coral diseases have been increasingly reported over the past few decades and are a major contributor to coral decline worldwide. The Caribbean, in particular, has been noted as a hotspot for coral disease, and the aptly named white syndromes have caused ...
