Sulfide-dependent Photoautotrophy in the Filamentous Anoxygenic Phototrophic Bacterium, Chloroflexus aggregans.

Microbes and environments, 2019
Chloroflexus aggregans is a thermophilic filamentous anoxygenic phototrophic bacterium frequently found in microbial mats in natural hot springs. C. aggregans often thrives with cyanobacteria that engage in photosynthesis to provide it with an organic substrate; however, it sometimes appears as the dominant phototroph in microbial mats without ...

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

A unique sessile loricate euglenid, Lepocinclis loricata sp. nov. (Euglenophyta, Phacaceae), from South Africa: Evolutionary implications

Journal of Phycology, Volume 62, Issue 3, Page 846-854, June 2026.
Abstract In this paper, we describe Lepocinclis loricata sp. nov. (Phacaceae), a sessile loricate euglenid that differs from all known loricate taxa by its unique combination of the presence of a lorica, monad morphology, sessile habit, and phylogenetic position within the Phacaceae. Populations of this species inhabit two turbid, silt‐rich waterbodies,

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

Sedimentology, Volume 73, Issue 4, Page 849-863, June 2026.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.

A Seasonal Record of Bacterial Communities in Micritized Carbonate Sediments of the Eastern Red Sea

Environmental Microbiology, Volume 28, Issue 5, May 2026.
Evidence of intense micritization is observed throughout Al Kharrar lagoon sediments (0–80 cm). Diverse bacterial communities with putative roles in carbonate cycling display depth‐related shifts. Their stable seasonal presence suggests sustained micritization beyond the photic zone, refining our understanding of the potential role of bacteria in early

The Microbiology and Geochemistry of the Shallow‐Water Hydrothermal Vents of the Gulf of Naples, Italy

Environmental Microbiology, Volume 28, Issue 4, April 2026.
This study investigated the interplay between fluid geochemistry and microbial diversity in the shallow‐water hydrothermal vents of the gulf of Naples, Italy. We found that hydrothermal fluid chemistry and the geological settings where the vents are hosted play a key role in shaping microbial distribution.

Analysis of Microalgae Growth in Residual Light: a Diagnostics Tool for Low-Cost Alternative Cultural Media

Chemical Engineering Transactions, 2014
Chapter 1 Most microalgae grow in photoautotrophy and some benefit from mixotrophy and their growth essentially depends on the effective available light intensity.

Hydrologic History Regulates Microbial Biofilm Diversity and Ecosystem Function

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hydrologic history regulates microbial biofilm diversity and ecosystem function. Historical flooding, but not drought, led to broad changes in composition and functional genes. ABSTRACT Aquatic biofilms are an understudied component of northern peatlands and are expected to play a more prominent role in ecosystem processes in areas where aquatic ...

Nitrogen Assimilation of Micropropagated Strawberry Plantlets during the Transition from Heterotrophy to Photoautotrophy [PDF]

HortScience, 1995
A study was conducted to determine the implication of nitrate reductase (NR) and glutamine synthetase (GS) during the transition of micropropagated plantlets from heterotrophy to photoautotrophy to document how nitrogen metabolism interfaces with photosynthetic and anaplerotic CO2 fixation.
